Boolean vs boolean in Java

Question

There are discussions around Integer vs int in Java. The default value of the former is null while in the latter it's 0. How about Boolean vs boolean?

A variable in my application can have 0/1 values. I would like to use boolean/Boolean and prefer not to use int. Can I use Boolean/boolean instead?

Answer 1

Yes you can use Boolean/boolean instead.

First one is Object and second one is primitive type.

• On first one, you will get more methods which will be useful.

• _{Second one is cheap considering memory expense} The second will save you a lot more memory, so go for it

Now choose your way.
