    安装 junit,hamcrest and eclemma

    • 安装 junit

    右键要测试的类 --> new --> JUnit Test Case ,就可以自动导入Junit,开始测试了。

    • 安装 hamcrest

    在新建的项目上:右键->properties->Java Build Path->Libraries->Add External JARs->选择 hamcrest-all-1.3.jar->OK。

    • 安装 eclemma

    菜单栏 -> Help -> Install New Software -> Add -> Local->选择下载的eclemma-2.3.3->确定->OK->Select All->Next->Finish。

    Write a java program

    • Judgeinter.java

    	 * @return 等边三角形;等腰三角形;普通三角形;不构成三角形
    	 */
    	String get_re();
    
    }
    
    • Judge.java
