convert from boolean to byte in java

Question

I need to set byte value as method parameter. I have boolean variable isGenerated, that determines the logic to be executed within this method. But I can pass directly boolean as byte parameter this is not allowed and can't be cast in java. So the solution I have now looks like this:

myObj.setIsVisible(isGenerated ? (byte)1 : (byte)0);

But it seems odd for me. Maybe some better solution exists to do this?

Answer 1

your solution is correct.

if you like you may avoid one cast by doing it the following way:

myObj.setIsVisible((byte) (isGenerated ? 1 : 0 ));

additionally you should consider one of the following changes to your implementation:

• change your method to something like setVisiblityState(byte state) if you need to consider more than 2 possible states

• change your method to setIsVisible(boolean value) if your method does what it's looking like

Answer 2

You can use this solution. I found it on this very useful page

boolean vIn = true;
byte vOut = (byte)(vIn?1:0);
