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());
  
         }
 }
