A） The brief description that you install junit, hamcrest and eclemma.

a）  install junit、hamcrest：
方式一：导入jar包。
1、鼠标右击项目名，点击‘Properties’一栏；
2、如下图点击‘Add External JARs’；

 

3、选中下载好的junit和hamcrest的jar包，打开即可。

 

方式二，添加junit库：
1、鼠标右击项目名，点击‘Properties’一栏；
2、如下图点击‘Add Library’；

 

3、选中Junit一栏，点击‘Next’；

 

4、选择Junit版本，之后点击‘Finish’。

 

b） install eclemma
1、下载jacoco，链接： http://www.eclemma.org/jacoco/ 根据系统选择适合的版本即可；
2、下载完成后，解压文件，将lib目录下的所有jar包放入eclipse安装目录的‘plugins’文件夹下；

 

3、在eclipse窗口依次点击HelpàEclipse Marktplaceà在‘Find’一栏输入：eclemmaà点击安装即可。

TriangleProblem.java:

package cn.tju.triangleproblem;

public class TriangleProblem {

    public TriangleProblem() {
        // TODO Auto-generated constructor stub
    }

    public String TriangleTypes(int a, int b, int c) {

        if (a + b > c && b + c > a && c + a > b) {
            if (a == b && b == c)
                return "equilateral";
            if (a == b || b == c || c == a)
                return "isosceles";

            return "scalene";
        } else
            return "Error, not a triangle!";

    }
