Java Program To Count Vowels and Consonants in a String
In this Java Program, we count the vowels and consonants in a string.
The alphabet contains 26 letters, among them A, E, I, O, U (small and upper case) are known as vowels while the remaining 21 letters are known as consonants.
Logic : String str = "Itengineer8995";
int vcount = 0, ccount = 0;
str = str.toLowerCase();
for(int i = 0; i < str.length(); i++)
{
char ch = str.charAt(i);
if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u')
{
vcount++;
}
else if((ch >= 'a' && ch <= 'z'))
{
ccount++;
}
}
Step 1 : Create variable str and store the string in it.
Step 2 : Create and initialize variable vcount to 0 and ccount to 0.
Step 3 : Convert all the chars to lowercase by using toLowerCase method of the String class and store it in the variable str.
Step 4 : Apply for loop where i is equal to 0, i should be less than length of the string and increment i.
Step 5 : Create variable char ch and store the string at char position i.
Step 6 : apply if else if statement. If ch is equal to a or ch is equal to e or ch is equal to i or ch is equal to o or ch is equal to u then increment the vcount. else if ch is greater than or equal to a and ch is less than or equal to z then increment ccount.
Step 7 : Print number of vowels and consonants.
Program :
public class VowelConsonant2
{
public static void main(String[] args)
{
String str = "Itengineer8995";
int vcount = 0, ccount = 0;
//converting all the chars to lowercase
str = str.toLowerCase();
for(int i = 0; i < str.length(); i++)
{
char ch = str.charAt(i);
if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u')
{
vcount++;
}
else if((ch >= 'a' && ch <= 'z'))
{
ccount++;
}
}
System.out.println("Number of Vowels :" +vcount);
System.out.println("Number of Consonants :" +ccount);
}
Output :
Number of Vowels :5
Number of Consonants :5
