Why boolean in Java takes only true or false? Why not 1 or 0 also?

Question

Is there any reason why Java booleans take only true or false why not 1 or 0 also?

Answer 1

Java, unlike languages like C and C++, treats boolean as a completely separate data type which has 2 distinct values: true and false. The values 1 and 0 are of type int and are not implicitly convertible to boolean.
