Java Algorithms-Symbols &

& and Operators

And the operator is denoted by the symbol "&", which uses the following rules:
Two operands have a bit of 1 and the result is 1, otherwise the result is 0

For example, the following program segment.

 Public class data13{publicstaticvoid  main (string[] args) {int a=129 ; int b=128; System.out.println ("A and B" with the result is: "+ (a&b));}}

Run results
A and B with the result is: 128
The following analysis of this program:

The value of "a" is 129, converted to binary is 10000001, and the value of "B" is 128, converted to binary is 10000000. According to the operator's operation Law, only two bits are 1, the result is 1, you can know the result is 10000000, that is, 128.
