Java bitwise OR operator

Bitwise OR Operator is -

  1. The OR operator, |, combines bits such that if either of the bits in the operands is a 1, then the resultant bit is a 1
  2. Binary Operator as it Operates on 2 Operands.
  3. Denoted by – |

Bitwise OR Summary Table :

ABA | B
000
011
101
111

 

Live Example 1 : ORing 42 and 15

class BitwiseOR {
  public static void main(String args[]){

  int num1 = 42;
  int num2 = 15;

  System.out.println("OR Result =" +(num1 | num2));

  }
}
[468×60]

Output :

OR Result = 47

Explanation of Code :

Num1 : 00101010   42
Num2 : 00001111   15
======================
OR   : 00101111   47
  • 42 is represented in Binary format as -> 00101010
  • 15 is represented in Binary format as -> 00001111
  • According to above rule (table) we get 00101111 as final structure.
  • println method will print decimal equivalent of 00101111 and display it on screen.

Live Example 2 : ORing Hex and Integer

class BitwiseOR{
  public static void main(String args[]){

  int num1 = 42;
  int num2 = 0xF;

  System.out.println("OR Result =" +(num1 | num2));

  }
}
  • Code will also gives 47 as a result.
  • 0xF is hexadecimal number.
  • 0xF is first converted into “decimal“.(Decimal Equivalent : 15)
  • Again Same Operation will takes place as that of “Live Example 1“.
Step 1: Converting Hex to Decimal

Num2  : F  (Hex)
      : 15 (Decimal Equivalent)
Step 2: Converting Decimal to Binary

Num1  : 00101010   42
Num2  : 00001111   15
======================
OR    : 00101111   47
