What is stored in a boolean variable in Java ? (as per the memory, bit patterns)

Question

I googled it and I found that it is virtual machine dependent. But still in what ways ?

Not at that level, a more abstract answer would be fine.Boolean variable is of 2 bytes in some VM, so a justification of that would be more than enough. Thank you. — JDoe

The Java spec makes no guarantees about anything like this. What JVM are you interested in? Hotspot? — Michael

In C, I used to create my own boolean types typedef int bool by defining 1 as true and 0 as false. So I think here is the same and it changes depending on the arch. — Yahya

boolean type will be converted to int

There are no Java Virtual Machine instructions solely dedicated to operations on boolean values. Instead, expressions in the Java programming language that operate on boolean values are compiled to use values of the Java Virtual Machine int data type.
