Java_ Study the next day (iii) [Logical operator (&) (|) (^) (! ）]

• Basic usage of logical operators

Class Demo {

public static void Main (string[] args) {

&,|,^,!

int a = 10;

int B = 20;

int c = 30;

Logic with & and False if it encounters false

System.out.println (a B & B c);//true & true = True

System.out.println (a B & B > c);//true & false = False

System.out.println (a) B & B C);//false & true = False

System.out.println (A > B & B > c);//false & false = False

Logic | Or or encounters true if True

System.out.println (A > B | b > c);//true & true = True

System.out.println (A > B | b > c);//true & false = True

System.out.println (A > B | b > c);//false & true = True

System.out.println (A > B | b > c);//false & false = False

Logical xor ^ on both sides of the same false, the difference is true

System.out.println (A > b ^ B > c);//true ^ true = False

System.out.println (A > b ^ B > c);//true ^ false = True

System.out.println (A > b ^ B > c);//false ^ true = True

System.out.println (A > b ^ B > c);//false ^ false = False

Logical Non! is equivalent to taking counter

SYSTEM.OUT.PRINTLN (! true);

SYSTEM.OUT.PRINTLN (!! true);
