Taking out the first character of each word Arrange the letters of the new word in ascending order
and display the resultant word,
Sample Input: Computer, History, Physics, Biology, Mathematics
New Word: CHPBM
Sample Output: BCHMP

Answer 1

Program:

import java.util.*;

public class MyClass

{

   public static void main(String args[])

   {

       Scanner Sc = new Scanner(System.in);

       String A[] = new String[5];

       char ch[] = new char[5];

       System.out.println("Enter five words in an array : ");

       for(int i = 0 ; i < 5 ; i++)

       {

           A[i] = Sc.next();

           ch[i] = A[i].charAt(0);

       }

       for(int i = 0 ; i < 5 ; i++)

       {

           for(int j = 0 ; j < 5-i-1 ; j++)

           {

               if(Character.compare(ch[j],ch[j+1]) > 0)

               {

                   char temp = ch[j];

                   ch[j] = ch[j+1];

                   ch[j+1] = temp;

               }

           }

       }

       for(int i = 0 ; i < 5 ; i++)

       {

            System.out.print(ch[i]);

       }

   }

}

Output:

Enter five words in an array :

Computer

History

Physics

Biology

Mathematics

BCHMP
