字符串中单词逆序的实现

import java.util.Stack;

public class StackTest {
 public static void main(String argv[]) {
  Stack<String> stack = new Stack<String>();
  for(String s : "I have a round peach".split(" ")) {
   stack.push(s);//按字符串原顺序压栈

  }
  while(!stack.empty()) {
   System.out.print(stack.pop() + " ");//弹栈并输出

  }
 }
}
