1. work2类

    package com.Phantom;
   
    import java.util.Scanner;
   
    import javax.print.DocFlavor.INPUT_STREAM;
   
    public class work2 {
   
        String str=null;
   
        StringBuffer re_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();
   
        }
   
    }

2. testing类

    package com.Phantom;
   
    import static org.junit.Assert.*;
   
    import junit.framework.TestCase;
   
    import org.junit.After;
   
    import org.junit.Before;
   
    import org.junit.Test;
   
    public class testing extends TestCase {
   
        private work2 w;
   
        @Before
   
        public void setUp() throws Exception {
   
            super.setUp();
   
            w=new work2();
   
        }
   
        @After
   
        public void tearDown() throws Exception {
   
            System.out.println("w.getStr()>>>"+w.getStr());
   
            System.out.println("w.getRe_str()>>>"+w.getRe_str());
   
        }
   
        @Test
   
        public void test() {
   
        //    fail("Not yet implemented");
   
            w.setStr("as sa");
   
            w.input();
   
            assertTrue(w.getRe_str().toString()=="sa as");}
   
    }
