Java Programs

 Q. Write a program to print first letters of each word in a string if it is a vowel.

 Explanation: Let us consider a string "Ellen is my cousin's friend"

 In the above string 'E' 'i' are first letters of string and it is vowel so it should print the two letters.

Program:  

import java.util.Scanner;

public class Main{

public static void main(String[] args) {

    Scanner sc=new Scanner(System.in);

    String st=sc.nextLine();

    String Words[]=st.split(" ");

    for(int i=0;i<Words.length;i++){

        String s=Words[i];

        s=s.toLowerCase();

     if(s.charAt(0)=='a'|| s.charAt(0)=='e'|| s.charAt(0)=='i'|| s.charAt(0)=='o'|| s.charAt(0)=='u'){

         System.out.println(s.charAt(0));

     }   

    }

}

}
