Differences between "|" and "|" in Java, and between java

Differences between "|" and "|" in Java, and between java

Example:

1 int a = 5; 2 int B = 10; 3 4 if (a> 4 | B ++> 10) {5 System. out. println ("a:" + a + "\ nb:" + B); 6}

Running result: a: 5
B: 11

 

1 int a = 5; 2 int B = 10; 3 if (a> 4 | B ++> 10) {4 System. out. println ("a:" + a + "\ nb:" + B); 5}

Running result: a: 5
B: 10

 

What are the differences between "|" and "|?

--"| ":If the operand after calculation on the left is true, the operation is not executed on the right. true is returned;

"|": Both operands are calculated.

That is to say, "|" does not have a short circuit.

Note: The difference between "&" and "&" is similar.& The first and second operands are always calculated, and & the first operand is calculated. If the left operand is false, false is returned, and the right operand is not calculated.
