What is the use of the & operator in Java?

The AND operator preserves non-Boolean values and returns them as they are: Even though the && operator can be used with non-Boolean operands, it is still considered a boolean operator since its return value can always be converted to a boolean primitive .

What is the difference between '&' and '&&' in Java?

The key difference between && and & operators is that && supports short-circuit evaluations while & operator does not. Another difference is that && will evaluate the expression exp1, and immediately return a false value if exp1 is false. While & operator always evaluates both expressions (exp1 and exp2) before retiring an answer.
