Bitwise OR : Bitwise Operators in Java Programming

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 :

A	B	A | B
0	0	0
0	1	1
1	0	1
1	1	1

 

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));
  }
}

[468x60]

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
