Operator Precedence
The operators that work on booleans have a "precedence order."
This is defines an order of operations similar to mathematics, where multiplication and division happen before addition and subtraction.
For booleans !
always happens first. This is followed by &&
and then by ||
.
boolean a = true;
boolean b = false
boolean c = false;
// just as 2 + 5 * 3 "evaluates" 5 * 3 before adding 2
// first, !b is true
// second, a && true is true
// third true || c is true.
boolean result = a && !b || c;
Also like mathematics, parentheses can be used to control this order.
// Even though || has a lower precedence than &&, we evaluate
// !b || c first because of the parentheses.
boolean result = a && (!b || c);
