java - 如何在Java中使用不同参数的构造函数之间交替？

我有一个包含2个构造函数的类，一个构造函数接受一个对象（鱼），另一个构造函数接受一个称为鱼的对象数组（鱼）。有一个向篮子里添加鱼的功能：

public Basket(int weight, Fish fishes) {
    singleFish = true;
}

public Basket(int weight, Fish[] fishes) {
    singleFish = false;
}


public boolean addFishes(Fish fish) {
    //here I want to make it so that when I add a fish to a basket,
    //it no longer uses the top constructor.
}

假设一个篮子以1条鱼开头，我如何才能使它取一条鱼并在取一条鱼后使用第二个构造函数？
非常感谢你。

最佳答案

public Basket(int weight, Fish fish) {
    this(weight, new Fish[] {fish};
    singleFish = true;
}

public Basket(int weight, Fish[] fishes) {
    singleFish = fishes.length == 1;
}

或者在这里，您只需要一个带有可变参数的构造函数（Fish...实际上是Fish[]类型）：

private final Fish[] fishes;
private final boolean singleFish;

public Basket(int weight, Fish... fishes) {
    this.fishes = fishes;
    singleFish = fishes.length == 1;
}

new Basket(45, hering, sardine, riba);
new Basket(75, shark);
