3. size for data type boolean    coderanch.com

The size of all other primitives in Java are well-defined, but the size of boolean is not. I not aware of any JVM suppliers documenting how they handle booleans. I think it's safe to say that it's most likely between 1 and 32 bits in length, though that probably doesn't help you much. In fact it's probably between 1 and 8 ...

as I understand it - it's not defined, and it doesn't matter. the authors of the JVM are free to make it whatever size they want or need to for whatever reason. They often choose a size that is most efficient on the specific platform their jvm will run on. but more importantly, it doesn't matter. you can't do any byte ...

Yes, you are wrong. It's whatever memory the JVM implementation would allocate for storing a 32-bit int, unless it's a boolean array. And unless, of course, the OP doesn'T refer to "memory size" when he talks about "size in Java". In Java, it would be either four (true) or five (false) letters...

The JVM doesn't have a notion of booleans. booleans are integral values (zero or not). In Sun's typical 32 bit implementations everything except doubles and longs take up four bytes in a class or object. booleans take up one byte in a boolean[]. Note that this is only true in nowadays Sun's Java implementations kind regards, Jos
