Program to reverse a given sentence in java

Write a program to reverse a sentence in Java

For example if you have a sentence "Quick brown fox jumped over a lazy dog",

your output should be "dog lazy a over jumped fox brown Quick"

package com.prasune.coding; import java.util.Stack; import java.util.StringTokenizer; public class ReverseSentence {       public static void main(String[] args) {             System.out.println(getReverseString("Quick brown fox jumped over a lazy dog"));       }       public static String getReverseString(String str){         StringTokenizer tokenizer = new StringTokenizer(str);         Stack<String> stack = new Stack<String>();         String reversedString = "";         while(tokenizer.hasMoreTokens()){           stack.push(tokenizer.nextToken());         }         while(!stack.empty()){               reversedString = reversedString + stack.pop() + " ";         }         return reversedString.trim();       } }
