Do you mean variables/indexes in a string array? or number of characters in a string variable?

do you mean length of string?? import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner sc=new Scanner(System.in); String str=sc.nextLine(); System.out.printf("Length is %s",str.length()); } }

import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner sc=new Scanner(System.in); int Vcount=0; int ConCount=0; System.out.println("enter string"); String str=sc.nextLine(); for(int i=0;i<str.length();i++){ if(str.charAt(i)=='a'|| str.charAt(i)=='e'|| str.charAt(i)=='i'||str.charAt(i)=='o'||str.charAt(i)=='u'){ Vcount++; } else { ConCount++; } } System.out.println("vowels are "+Vcount); System.out.println("Coms are "+ConCount); System.out.println("code by ManikanthVanka"); } }

for(int i = 0; i < str.length(); i++) if(str.charAt(i) == 'a') numVowels++; Use an if in the for loop for each vowel or use the same if by using the OR operator ||. Very quick and easy.
