Write a program in java to accept a string and count the number of the Vowels present in the string

import java.util.*;
class stringexample
{
    public static void main(String args[])
    {
        Scanner sc= new Scanner(System.in);
        String n;
        char ch;
        int c=0;
        System.out.println("Enter the String");
        n=sc.next();
        for(int i=0;i<n.length();i++)
        {
        ch=n.charAt(i);
        if(ch=='A'||ch=='a'||ch=='E'||ch=='e'||ch=='I'||ch=='i'||ch=='O'||ch=='o'||ch=='U'
        ||ch=='u')
        c++;
        }
        System.out.println("Vowels="+c);
       
    }
}
