Reverse Words and Letters in String

The following example illustrates reversing words and letters in a string. This is in fact a Google interview question and now it's solved in Java.

// import for java.util.Scanner class

import java.util.*;

class GoogleReverseString

{

        public static void main(String args[])

        {



        // Create Scanner object for taking input from cmd

        Scanner s=new Scanner(System.in);





        // Read input from the user

        String st=s.nextLine();



        

        // Create StringBuffer object for st

        StringBuffer sb=new StringBuffer(st);





        // Print the reversed string

        System.out.println("Reversed String is "+sb.reverse());



        // Split the word with a space

        String[] w=sb.toString().split(" ");



        String temp="";

        

          for(int i=w.length-1;i>=0;i--)

          {

          temp+=w[i]+" ";

          }



        // Trim extra space & print

        System.out.println(temp.trim());

 

        }

}
