 Q Write a program to reverse each word in an inputted string.

Example: Hello Students becomes olleH stnedutS 

SOLUTION:

import java.lang.String;

import java.lang.StringBuffer;

import java.util.Scanner;

class q4

{

    public static void main(String args[])

    {

         String str;

         String str1 = new String();

         StringBuffer temp;

         int count = 0,i,j,k = 0;

         int b,e;

         Scanner sc = new Scanner(System.in);

         System.out.println("Enter a String: ");

         str = sc.nextLine();

         str = str.trim();

         for(i=0;i<str.length();++i)

         {

             if(str.charAt(i) == ' ')

                ++count;

         }

         if(count == 0)

        {

            temp = new StringBuffer(str);

            temp.reverse();

            System.out.println(temp);

            System.exit(0);

        }

         b = 0;

         for(i=0;i<str.length();i++)

         {

             if(str.charAt(i) == ' ')

             {  ++k;

                e = i;

                temp = new StringBuffer(str.substring(b,e));

                temp.reverse();

                str1 = str1.concat(String.valueOf(temp));

                str1 = str1.concat(" ");

                b = e + 1;

                if(k == count)

                {   temp = new StringBuffer(str.substring(b));

                    temp.reverse();

                    str1 = str1.concat(String.valueOf(temp));

                    break;

                }

             }

         }  System.out.println(str1);

    }

}

OUTPUT:
