java 面向对象编程练习题，急求答案~ 用MyEclipse编写
练习题】10.构造方法与重载、包

编写Addition类，该类中应包含一组实现两数相加运算的重载方法。

实现加法运算的方法，应接受两个参数（即加数和被加数），方法将两个参数进行加法运算后，返回相加结果。考虑可能针对不同的数据类型进行计算，重载一组方法，包括整型、长整型、浮点型、双精度浮点型、还有字符串。

在main方法中创建Addition类的实例，分别调用重载方法测试其效果。

应将Addition类打入到包中，以自己名字的拼音为包命名。

Answer 1

public class WuMingFen {

private String theMa ;
private int quantity ;
private boolean likeSoup ;

public static void main(String[] args) {
WuMingFen f3 = new WuMingFen();
f3.setLikeSoup(true);
f3.setTheMa("酸辣面");
f3.setQuantity(2);
check(f3);

}

private static void check(WuMingFen fen){

System.out.println("这是："+fen.getTheMa());
System.out.println("分量："+fen.getQuantity());
if(fen.isLikeSoup()){
System.out.println("带汤");
}else{
System.out.println("不带");
}

}
public WuMingFen(String theMa, int quantity) {
this.theMa = theMa;
this.quantity = quantity;
}
public WuMingFen() {

}
public WuMingFen(String theMa, int quantity, boolean likeSoup) {
super();
this.theMa = theMa;
this.quantity = quantity;
this.likeSoup = likeSoup;
}
public String getTheMa() {
return theMa;
}

public void setTheMa(String theMa) {
this.theMa = theMa;
}

public int getQuantity() {
return quantity;
}

public void setQuantity(int quantity) {
this.quantity = quantity;
}

public boolean isLikeSoup() {
return likeSoup;
}

public void setLikeSoup(boolean likeSoup) {
this.likeSoup = likeSoup;
}
@Override
public String toString() {
return "WuMingFen [theMa=" + theMa + ", quantity=" + quantity
+ ", likeSoup=" + likeSoup + "]";
