java – 将Enum成员传递给构造函数：“实际和形式参数列表的长度

中央供暖控制：

Radiator类和RadiatorSize类. Radiator有一个size实例变量,它是Class RadiatorSize.我有XSMALL,…… XLARGE用于散热器的尺寸;在RadiatorSize中定义为公共枚举.

所以,我在想,创造一个新的散热器并给它一个MEDIUM尺寸.

size = new RadiatorSize(RadiatorSize.Size.MEDIUM);

Netbeans告诉我这个：

...CentralHeatingsrchardwaremodelRadiator.java:17:
error: constructor RadiatorSize in class RadiatorSize cannot be
applied to given types;

size = new RadiatorSize(RadiatorSize.Size.MEDIUM);
required: no arguments
found: Size
reason: actual and formal argument lists differ in length
1 error

这是违规的课程.

/** Radiator class **/
package hardwaremodel;

import units_constants.RadiatorSize;

public class Radiator {
    private int boilerSequence;
    private RadiatorSize size;
    private double volume; //cubic centimetres

public void Radiator(int blrSqnc) {
    boilerSequence = blrSqnc;
    size = new RadiatorSize(RadiatorSize.Size.MEDIUM); //ERROR HERE
    }
}


/** RadiatorSize class **/
package units_constants;

public class RadiatorSize {
    public enum Size {XSMALL,SMALL,MEDIUM,LARGE,XLARGE};

    private Size size;

    public void RadiatorSize(Size sz) {
        size = sz;
    }
}

现在,Netbeans给了我一个提示,它建议在units_constants.RadiatorSize中创建Constructor RadiatorSize(units_constants.RadiatorSize.Size);当我同意时它会这样做：

public RadiatorSize(Size size) {
    throw new UnsupportedOperationException("Not yet implemented");
}

现在编辑器中现在没有小红圈,但是……！

我很困惑.
