For some reason I have to maintain a Java 1.3 project. I use some Boolean but it seems that to give them default values I have to box them like this

Boolean disableAllTheThings = new Boolean(false);

Is there a way to have this automatically with a constant somewhere such as

Boolean disableAllTheThings = FALSE_CONSTANT;

It is not that important it just feels weird to box Booleans.

有帮助吗?

解决方案

There is no boxing in your example, but you create an unnecessary object. How about using the constant provided by the Boolean class (link to 1.3 API) instead:

Boolean disableAllThings = Boolean.FALSE;

其他提示

I think you're looking for Boolean.FALSE (and Boolean.TRUE). They were around since the beginning of Java, and they certainly were there in Java 1.3.1.
