The && operator also known as conditional-AND operator or short circuit AND. This operator exhibit “short-circuiting” behavior, which means that the second operand is evaluated only if needed.
The && operator evaluate only boolean values. For an AND (&&) expression to be true, both operands must be true. If the first operand resolves false, then the && operator will not evaluate the second operand, because it already know the complete expression will return false.
package org.kodejava.basic;
public class ConditionalANDDemo {
public static void main(String[] args) {
// second operand (2<3) is not evaluated, because the first
// operand return false the result of complete expression
// can't be true
boolean a = (5 < 3) && (2 < 3);
// first operand return true, second operand is evaluated
// to check the result of the second expression if second
// operand resolves to true, the complete expression return
// false, otherwise return false
boolean b = (1 == 1) && (2 < 3);
boolean c = (1 == 1) && (5 < 3);
System.out.println("result a: " + a);
System.out.println("result b: " + b);
System.out.println("result c: " + c);
}
}
The result of the code snippet:
result a: false
result b: true
result c: false
