“构造函数不能应用于给定类型”当构造函数具有继承性时 [英] "Constructor cannot be applied to given types" when constructors have inheritance

问题描述

这是我的基类：

abstract public class CPU extends GameObject {
    protected float shiftX;
    protected float shiftY;

    public CPU(float x, float y) {
        super(x, y);
    }

这是其子类之一：

public class Beam extends CPU {
    public Beam(float x, float y, float shiftX, float shiftY, int beamMode) {
        try {
            image = ImageIO.read(new File("/home/tab/Pictures/Beam"+beamMode+".gif"));
        } catch (Exception e) {
            e.printStackTrace();
        }
        this.x = x;
        this.y = y;
        this.shiftX = shiftX;
        this.shiftY = shiftY;
    }

New构造函数突出显示，并显示：

The New constructor is highlighted and it says:

Constructor CPU in class CPU cannot be applied to given types:
required: float, float
found: no arguments

如何解决？

推荐答案

由于错误试图告诉您，您需要将参数传递给基类的构造函数。

As the error is trying to tell you, you need to pass parameters to your base class' constructor.

添加 super（ x，y）;
