Boolean and bitwise operators for Java

1. Boolean operators

&& logic and;

|| logical OR;

! = does not equal;

Ternary operator:?:; expression is condition? Expression1:expression2 (returns the value of expression1 when the condition is true, otherwise returns the value of expression2);

&& "and" and | | " Or "are evaluated in a short-circuit manner, so the first operation can determine the value of an expression without calculating the second operation.

For example: x!=0&&1/x>x+y//Avoid infinite error when x=0;

2. Bitwise operators

& "and", | ("or"), ^ ("xor"), ~ ("non")

bitwise calculations, such as

0&0=0, 1&0=0, 0&1=0, 1&1=1;

0|0=0, 1|0=1, 0|1=1, 1|1=1;

0^0=0, 1^0=1, 0^1=1, 1^1=0;
