安裝過程：在bulid path上選擇junit，然後選擇Junit 4，其中自帶Junit和hamcrest，然後在eclipse Marketplace中安裝eclemma，最後重新開機eclipse。
Triangle.java:
package cn.tju.scs;
public class Triangle {
private int one;
private int two;
private int three;
public static boolean isLegal(int len1, int len2, int len3){
if(len1 <= 0 || len2 <= 0 || len3 <= 0)
return false;
if(len1 + len2 > len3 && len2 + len3 > len1 && len1 + len3 > len2)
return true;
return false;
}
public Triangle(int side_1, int side_2, int side_3){
if(isLegal(side_1, side_2, side_3)){
one = side_1;
two = side_2;
three = side_3;
}
else
System.out.println("不合法！");
}
public boolean isEquilatera(){
if(one == two && one == three)
System.out.print("等邊！ ");
else
System.out.print("非等邊！ ");
return (one == two && one == three);
}
public boolean isIsosceles(){

System.out.print("等腰！ ");

System.out.println(tri.isEquilatera());
System.out.println(tri.isIsosceles());
