Java Program To Calculate Power of a Number using pow() function


Java Program To Calculate Power of a Number using pow() function

In this Java Program, we calculate the power of the number using while loop.

The Power (exponent) of the numbers says how many times to use the number in a multiplication. It is written in a small number right and above the base number. 

E.g. the little 3 says to use 10 two times in a multiplication.

                     103 = 10 * 10 * 10 = 1000 

Logic :  result = Math.pow(number, p);

Step 1 : Create the variables named as number and p and store 10 in number and 3 in p.

Step 2 : Create variable result, Use the Math.pow() function to calculate the power of the number and store the result in the variable named result.

Step 3 : Display the result by using the System.out.print.

Program :

public class Power2 
    {
        public static void main(String[] args)
        {
            int number = 10, p =3;
            double result = Math.pow(number, p);
            System.out.println(number+"^"+p+"="+result);
        }
}

Output:

10^3 = 1000

Java Program To Calculate Power of a Number Using While Loop


Java Program To Calculate Power of a Number Using While Loop

In this Java Program, we calculate the power of the number using while loop.

The Power (exponent) of the numbers says how many times to use the number in a multiplication. It is written in a small number right and above the base number.

E.g. the little 2 says to use 5 two times in a multiplication.

                       52  = 5 * 5 = 25 

 Logic :    while(i!=0)
            {
                result *= number;
                --i;
            }

Step 1 : Create variable number and store the number 5 in it, similarly create variable p and store 2 in it.

Step 2 : Create variable result and store 1 in it.

Step 3 : Initialize i to p.

Step 4 : Apply the while loop

Step 5 : Do the multiplication and store the number into the variable result.

Step 6 : Decrement the i

Step 7 : Display the result by using System.out.print.
 
Program :

public class Power 
    {
        public static void main(String[] args)
        {
            int number = 5, p = 2;
            long result = 1;
            
            int i = p;
            while(i!=0)
            {
                result *= number;
                --i;
            }
            System.out.println(number+"^"+p+ "="+result);
                   
        }
    
}

Output:

2^5 = 32

Java Program To Find Quotient and Remainder


Java Program To Find Quotient and Remainder

In this Java Program, we find the Quotient and Remainder of the given two numbers.

The Quotient is the quantity produced by the division of the two numbers while the Remainder is the integer left over after dividing one integer by another.
             
E.g.                  7       👈 Quotient 
                     ___
                  2 | 15
                   -  14
                    ____
                         1       👈 Remainder
                               

In the above example, we take two numbers num 1 = 15 and num 2 = 2, where num 1 is the dividend and num 2 is the divisor.  When num 1 is divided by the num 2 we get the quotient as 7 and remainder as 1.

Logic : quotient = num 1 / num 2
          : remainder = num 1 % num 2

Step 1 : Create variables num1 and num2 and store the numbers 15 in num1 and 2 in num2.

Step 2 : Create variable quotient and apply the logic and store the result into the variable quotient.

Step 3 : Create variable remainder and apply the logic and store the result into the variable remainder.

Step 4 : Display the result by using the System.out.print.

Program :

public class QuotientRemainder 
    {
        public static void main(String[] args)
        {
            int num1 = 15, num2 = 2;
            int quotient = num1 / num2;
            int remainder = num1 % num2;
            System.out.println("Quotient is:" +quotient);
            System.out.println("Remainder is:" +remainder);
        }
    
}

Output:

Quotient is : 7
Remainder is : 1

Java Program To Calculate Simple Interest


Java Program To Calculate Simple Interest

In this Java Program, we calculate Simple Interest.

The interest calculated on the principal amount of the loan is called as simple interest. It is determined by calculating the daily interest rate by the principal by the number of days that elapse between payments.

                                         Simple Interest = (P * R * T) / 100

P = Principal amount
R = Rate per annum
T = Time in years

Let's say a man deposit 2000 INR in a bank account at an interest rate of 6% per annum for 3 years, calculate the simple interest at the end of 3 years.

Simple Interest = 2000 * 6 * 3 / 100 = 360 INR

Logic : sinterest = (p * r * t) / 100

Step 1 : Import java.util.Scanner

Step 2 : Create variables p, r, t, sinterest.

Step 3 : Ask the user to enter the principal by using the Scanner 

Step 4 : Store the user entered principal in the variable named p

Step 5 : Ask the user to enter the rate of interest by using the Scanner 

Step 6 : Store the user entered rate of interest in the variable named r

Step 7 : Ask the user to enter the time period by using the Scanner 

Step 8 : Store the user entered time period in the variable named t

Step 9 : Close the Scanner to avoid memory leak

Step 10 : Calculate the simple interest by using the logic and store it in the variable named sinterest.

Step 11 : Display the result using System.out.print.

Program :

import java.util.Scanner;

public class SimpleInterest
    {
        public static void main(String[] args)
        {
            float p, r, t, sinterest;
            Scanner sc = new Scanner(System.in);
            System.out.print("Enter the Principal:");
            p = sc.nextFloat();
            System.out.print("Enter the Rate of interest:");
            r = sc.nextFloat();
            System.out.print("Enter the Time period:");
            t = sc.nextFloat();
            sc.close();
            sinterest = (p * r * t) / 100;
            System.out.print("Simple Interest is:"+sinterest);
                
        }
    
}

Output:

Enter the Principal : 2000
Enter the Rate of interest : 6
Enter the Time period : 3
Simple Interest is : 360.0

Java Program To Calculate Compound Interest


Java Program To Calculate Compound Interest

In this Java Program, we calculate the Compound Interest.

The addition of interest to the principal sum of loan or deposit or in other words interest on interest is called as Compound Interest.

                                                P (1 + R/n) (nt) - P

Here, P = Principal Amount
      R = annual interest rate
      t = time the money is invested or borrowed for.
      n = number of times the interest is compounded per unit t


Let's say an amount of  $2,000 is deposited into a bank account as a fixed deposit at an annual interest rate of 8 %, compound monthly, the compound interest after 5 years would be:

P  = 2000
R = 8/100 = 0.08 (decimal)
n = 12
t =  5

Let's put these values into the formula

Compound Interest : 2000 (1 + 0.08 / 12)(12 * 5) - 2000 = $979.69

So, the compound interest after 5 years is $979.69

Logic : double amount = p * Math.pow(1 + (r / n), n * t);
             double cinterest = amount - p;

Step 1 : Create class CompoundInterest

Step 2 : Create method calculate and initialize variables p, t, r and n.

Step 3 : Apply the logic 

Step 4 : Call the object of the CompoundInterest Class in the main method. 

Program :

public class CompoundInterest 
    {
        public void calculate(int p, int t, double r, int n)
        {
            double amount = p * Math.pow(1 + (r / n), n * t);
            double cinterest = amount - p;
            System.out.println("Compound Interest after " + t + "years:" + cinterest);
            System.out.println("Amount after " + t + "years:" + amount);
        }
        
        public static void main (String[] args)
        {
            CompoundInterest obj = new CompoundInterest();
            obj.calculate(2000, 5, .08, 12);
        }
    
}

Output:

Compound Interest after 5 years : 979.6914
Amount after 5 years : 2972.69141660321

Java Program To Check Leap Year


Java Program To Check Leap Year

In this Java Program, we check whether the year entered by the user is a leap year or not.

The year which is exactly divisible by 4 is a Leap Year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400.

For e.g. the years 1700, 1800 and 1900 are not leap years, but the years 1600 and 2000 are leap years.

Logic :    if(year % 4 == 0)
                {
                    if(year % 100 == 0)
                    {
                        if(year % 400 == 0)
                            isLeap = false;
                    }
                    else

                }
                else {
                    isLeap = false;
                }

Step 1 : Import java.util.Scanner

Step 2 : Create a variable named year.

Step 3 : Ask the user to enter the year by using System.out.println method.

Step 4 : Store the user entered year in the variable year.

Step 5 : Close the Scanner to avoid memory leak.

import java.util.Scanner;

public class LeapYear 
        {
            public static void main(String[] args)
            {
                int year;
                Scanner sc = new Scanner(System.in);
                System.out.println("Enter any Year:");
                year = sc.nextInt();
                sc.close();
                boolean isLeap = false;
                
                if(year % 4 == 0)
                {
                    if(year % 100 == 0)
                    {
                        if(year % 400 == 0)
                            isLeap = false;
                    }
                    else
                        isLeap = true;
                }
                else {
                    isLeap = false;
                }
                if(isLeap == true)
                    System.out.println(year +"is a Leap Year");

Java Program to add two complex numbers


Java Program to add two complex numbers


In this Java Program, we perform addition of two complex numbers.


Complex numbers generally consists of two parts, real number and imaginary number. In this program, we add real number together and imaginary numbers together. The imaginary number has a letter i written after the number. Eg. 2i, 5i etc.


                                    2 + 5i  + 4 + 3i = 6 + 8i


Step 1 : Create two variables named real and img to store both the numbers.


Step 2 : Create a Constructor to initialize the complex number. For e. g. when we create an instance of this class like this ComplexNumber temp = new ComplexNumber(0, 0); it actually creates a complex number 0 + 0i.


Step 3 : Declare a method sum() to add the two numbers by adding their real and imaginary parts together.


Step 4 : Create a temporary complex number to hold the sum of the two numbers.


Step 5 : Return the output complex number.


Step 6 : Display the result by using System.out.printf.


Program :


public class AddTwoComplexNumbers

    {

        //for real and imaginary parts of complex numbers

        double real, img;

     

        //constructor to initialize the complex number

        AddTwoComplexNumbers(double r, double i)

        {

            this.real = r;

            this.img = i;

        }

     

        public static AddTwoComplexNumbers sum(AddTwoComplexNumbers a1, AddTwoComplexNumbers a2)

        {

            //creating a temporary complex number to hold the sum of two numbers

            AddTwoComplexNumbers temp = new AddTwoComplexNumbers(0,0);

         

            temp.real = a1.real + a2.real;

            temp.img = a1.img + a2.img;

         

            //returning the output complex number

            return temp;

        }

     

        public static void main(String [] args)

        {

            AddTwoComplexNumbers a1 = new AddTwoComplexNumbers(5.5,4);

            AddTwoComplexNumbers a2 = new AddTwoComplexNumbers(1.2,3.5);

            AddTwoComplexNumbers temp = sum(a1,a2);

            System.out.printf("Sum is:"+temp.real+" + "+temp.img+"i");

        }

Step 8 : Perform the addition of the two numbers entered by the user with the help of  "+" operator and store the result in the variable named as sum.


Step 9 : Display the result by using the System.out.println method. 


Program :

 

import java.util.Scanner;


public class AddTwoNumbers2

    {

        public static void main(String[] args)

        {

            int num1, num2, sum;

            Scanner sc = new Scanner(System.in);

            System.out.println("Enter First Number:");

            num1 = sc.nextInt();

         

            System.out.println("Enter Second Number:");

            num2 = sc.nextInt();

         

            sc.close();

            sum = num1 + num2;

            System.out.println("Sum of these numbers:"+sum);

         

        }
