此C＃代码的Java等价代码是什么？

Question

I am not sure how to implement this C# code into java? Dev is class that has this code.

    public enum ConfigSetupByte0Bitmap
    {
        Config5VReg = 0x80,
        ConfigPMux  = 0x40, 
    }

   public void SetVReg(bool val)
    {
        //vReg = val;
        if (val)
        {
            configSetupByte0 |= (int)Dev.ConfigSetupByte0Bitmap.Config5VReg;
        }
        else
        {
            configSetupByte0 &= ~(int)Dev.ConfigSetupByte0Bitmap.Config5VReg;   
        }
    }

Answer 1

I'm not a C# expert, but I think that this is functionality equivalent:

public void SetVReg(bool val) {
    if (val) {
        configSetupByte0 |= 0x80;
    } else {
        configSetupByte0 &= ~0x80;   
    }
}

The rest is just sugar.

But in SetVReg method, it says cannot cast ConfigSetupByte0Bitmap.Config5VReg to int.

That's right. In Java, enums are object types, and can't be cast to integers. If you want a Java enum with an integer "value" you need to do something line this:

    public enum Foo {
        ONE(1), THREE(3);
        public final value;
        Foo(int value) {
            this.value = value;
        }
    }

    // ...
    System.out.println("THREE is " + THREE.value);

Answer 2

public enum ConfigSetupByte0Bitmap
{
    Config5VReg(0x80),
    ConfigPMux(0x40); 

    public final int value;

    private ConfigSetupByte0Bitmap(final int value)
    {
        this.value = value;
    }
}

public void SetVReg(boolean val)
{
    //vReg = val;
    if (val)
    {
        configSetupByte0 |= ConfigSetupByte0Bitmap.Config5VReg.value;
    }
    else
    {
        configSetupByte0 &= ~ConfigSetupByte0Bitmap.Config5VReg.value;   
    }
}
