When Java evaluates a conjunction ( && ), does it eval exp2 if exp1 is false?

Question

I\'m wondering if it\'s guaranteed that in a Java program, the boolean expression on the right of a conjunction (exp2 above) will NOT be evaluated as long as the expression

Answer 1

From the Java Language Specification, 15.23 Conditional-And Operator &&:

The && operator is like & (§15.22.2), but evaluates its right-hand operand only if the value of its left-hand operand is true.

So the language spec guarantees that the right-hand side of your expression will not be evaluated if the left hand side is false.
