實驗步驟
（一）敏捷開發與XP
一.敏捷開發與XP實踐-1

①實驗要求：

敏捷開發與XP實踐 http://www.cnblogs.com/rocedu/p/4795776.html, Eclipse的內容替換成IDEA

參考 http://www.cnblogs.com/rocedu/p/6371315.html#SECCODESTANDARD 安裝alibaba 插件，解決代碼中的規范問題。

在IDEA中使用工具（Code->Reformate Code）把下面代碼重新格式化，再研究一下Code菜單，找出一項讓自己感覺最好用的功能。提交截圖，加上自己學號水印。

②實驗代碼：

public class CodeStandard {
public static void main(String [] args){
StringBuffer buffer = new StringBuffer();
buffer.append('S');
buffer.append("tringBuffer");
System.out.println(buffer.charAt(1));
System.out.println(buffer.capacity());
System.out.println(buffer.indexOf("tring"));
System.out.println("buffer = " + buffer.toString());
if(buffer.capacity()<20)
buffer.append("1234567");
for(int i=0; i<buffer.length();i++)
System.out.println(buffer.charAt(i));
}
}

產品代碼：
public class CodeStandard {
public static void main(String[] args) {
StringBuffer buffer = new StringBuffer();
buffer.append('S');
buffer.append("tringBuffer");
System.out.println(buffer.charAt(1));
System.out.println(buffer.capacity());
System.out.println(buffer.indexOf("tring"));
System.out.println("buffer = " + buffer.toString());
if (buffer.capacity() < 20)
buffer.append("1234567");
for (int i = 0; i < buffer.length(); i++)
System.out.println(buffer.charAt(i));
}
}

二.敏捷開發與XP實踐-2

①實驗要求：

在碼云上把自己的學習搭檔加入自己的項目中，確認搭檔的項目加入自己后，下載搭檔實驗二的Complex代碼，加入不少于三個JUnit單元測試用例，測試成功后git add .; git commit -m "自己學號 添加內容"；git push;

提交搭檔項目git log的截圖，包含上面git commit的信息，并加上自己的學號水印信息。

②實驗代碼：

1.搭檔碼云鏈接：https://gitee.com/pyc-1751/chapter_1_of_java.git

2.產品代碼：

public class Complex {
// 定義屬性并生成getter,setter
double RealPart;
double ImagePart;

// 定義構造函數
public Complex(){
}
public Complex(double R,double I){
RealPart=R;
ImagePart=I;
}

//Override Object
public boolean equals(Complex m){
if(m.RealPart==this.RealPart&&m.ImagePart==this.ImagePart){
return true;
}
else{
return false;
}
}
public String toString(){
if (this.RealPart != 0 && this.ImagePart > 0) {
return this.RealPart + " + " + this.ImagePart + "i";
} else if (this.RealPart != 0 && this.ImagePart == 0) {
return String.valueOf(this.RealPart);
} else if (this.RealPart != 0 && this.ImagePart < 0) {
return this.RealPart + " - " + -this.ImagePart + "i";
} else if (this.RealPart == 0 && this.ImagePart != 0) {
return this.ImagePart + "i";
} else {
return "0";
}
}

// 定義公有方法:加減乘除
Complex ComplexAdd(Complex a){
return new Complex(this.RealPart + a.RealPart, this.ImagePart + a.ImagePart);
}
Complex ComplexSub(Complex a){
return new Complex(this.RealPart - a.RealPart, this.ImagePart - a.ImagePart);
}
Complex ComplexMulti(Complex a){
return new Complex(this.RealPart * a.RealPart - this.ImagePart * a.ImagePart,
this.ImagePart * a.RealPart + this.RealPart * a.ImagePart);
}
Complex ComplexDiv(Complex a){
return new Complex((this.ImagePart * a.ImagePart + this.RealPart * a.RealPart) / (a.ImagePart * a.ImagePart + a.RealPart * a.RealPart),
(this.RealPart * a.ImagePart - this.ImagePart * a.RealPart) / (a.ImagePart * a.ImagePart + a.RealPart * a.RealPart));
}

}

測試代碼：
import junit.framework.TestCase;
public class ComplexTest extends TestCase {
Complex a = new Complex(1, 5);
Complex b = new Complex(2, -3);

public void testEquals() {
assertEquals(true, a.equals(a));
assertEquals(false, b.equals(a));
}

public void testToString() {
assertEquals("1.0 + 5.0i", a.toString());
assertEquals("2.0 - 3.0i", b.toString());
}

public void testComplexAdd() {
assertEquals("3.0 + 2.0i",a.ComplexAdd(b).toString());
assertEquals("4.0 - 6.0i",b.ComplexAdd(b).toString());
}

public void testComplexSub() {
assertEquals("-1.0 + 8.0i",a.ComplexSub(b).toString());
assertEquals("0",b.ComplexSub(b).toString());
}

public void testComplexMulti() {
assertEquals("-24.0 + 10.0i",a.ComplexMulti(a).toString());
assertEquals("17.0 + 7.0i",a.ComplexMulti(b).toString());
}

public void testComplexDiv() {
assertEquals("1.0",a.ComplexDiv(a).toString());
}

}
