The & operator produces true only if both its operands evaluate to true. If either x or y evaluates to false, x & y produces false (even if another operand evaluates to null). Otherwise, the result … See more The unary prefix ! operator computes logical negation of its operand. That is, it produces true, if the operand evaluates to false, and false, if the operand evaluates to true: The unary postfix ! operator is the null-forgiving operator. See more The ^ operator computes the logical exclusive OR, also known as the logical XOR, of its operands. The result of x ^ y is true if x evaluates to true and y evaluates to false, or x evaluates to false and y evaluates to true. … See more The & operator computes the logical AND of its operands.
