About Booleans

A Boolean variable has one of two values: true or false. The words true and false are also reserved words, are case insensitive, and are called Boolean literals.

These variables not the same as the strings true and false nor are they the same as any numeric value like 1 or 0. Booleans are not numbers or strings. They are simply Booleans.

Note	The Boolean class is spelled with an initial capital letter, but the Java boolean data type is all lowercase.
