为"无名的粉"写一个类：class WuMingFen 要求： 1.有三个属性：面码:String theMa 粉的份量(两)：int quantity 是否带汤：boolean likeSoup 2.写一个构造方法，以便于简化初始化过程，如： WuMingFen f1 = new WuMingFen("牛肉",3,true); 3.重载构造方法，使得初始化过程可以多样化： WuMingFen f2 = new WuMingFen("牛肉",2); 4.如何使得下列语句构造出来的粉对

class WuMingFen {
private String theMa; // 面码
private int quantity; // 粉的份量(两)
private boolean likeSoup; // 是否带汤

// 构造方法，初始化属性
public WuMingFen(String theMa, int quantity, boolean likeSoup) {
this.theMa = theMa;
this.quantity = quantity;
this.likeSoup = likeSoup;
}

// 重载构造方法，部分属性有默认值
public WuMingFen(String theMa, int quantity) {
this(theMa, quantity, false); // 默认不带汤
}

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;
}
}

// 构造出来的粉对象
WuMingFen f1 = new WuMingFen("牛肉", 3, true);
WuMingFen f2 = new WuMingFen("牛肉", 2); // 默认不带汤的粉对象
