Description of triangle problem:

Function triangle takes three integers a,b,c which are length of triangle sides; calculates whether the triangle is equilateral, isosceles, or scalene. 

簡單地判斷一個三角形的形狀

軟體結構如下：

Triangle的內容：

判斷三角形的形狀的代碼如下：

public String type(Triangle tri){        if(isTriangle(tri)){                        if(isIsosceles(tri)){                return "isoscele";            }            if(isScalene(tri)){                return "equilateral";            }            return "scalene";        }        return "not a triangle";    }

TriangleTest的內容如下：

package cn.tjuscs.st;import org.junit.Before;import org.junit.Test;import org.junit.runner.RunWith;import org.junit.runners.Parameterized;import java.util.Arrays;import java.util.Collection;import static org.junit.Assert.assertEquals;@RunWith(Parameterized.class)public class TriangleTest {        private Triangle tri;    private int input1;    private int input2;    private int input3;    private String expected;        public TriangleTest(int input1, int input2, int input3, String expected){        this.input1 = input1;        this.input2 = input2;        this.input3 = input3;        this.expected = expected;    }        @Before    public void setUp(){        tri = new Triangle(input1, input2, input3);    }        @Parameterized.Parameters    public static Collection<Object[]> getData(){        return Arrays.asList(new Object[][]{                {2,2,2,"equilateral"},                {2,4,3,"scalene"},                {2,3,3,"isoscele"},                {2,9,2,"not a triangle"}        });    }        @Test    public void testTriangle() throws Exception{        assertEquals(this.expected, tri.type(tri));    }    }
