   import java.util.Scanner;
   
   import javax.print.DocFlavor.INPUT_STREAM;
   
   public class work2 {
       String str=null;

       public String getStr() {
           return str;
       }
   
       public void setStr(String str) {
           this.str = str;
       }
   
       public StringBuffer getRe_str() {
           return re_str;
       }
   
       public work2() {
           super();
       }
   
       public String input(){
           System.out.println("请输入内容:");
           //str = "how are you";
           String strs[] = str.split(" ");
           re_str = new StringBuffer();
           for(int i = strs.length-1; i >= 0; i--){
               //测试
               //System.out.println(strs[i]);
               re_str.append(" "+strs[i]);
           }
           System.out.println("输出:"+re_str);
           return re_str.toString();
       }
