r = p | q; /* Binary representation 61 = 0011 1101 */
System.out.println("p | q = " + r );
r = p ^ q; /* Binary representation 49 = 0011 0001 */
System.out.println("p ^ q = " + r );
r = ~p; /* Binary representation -61 = 1100 0011 */
System.out.println("~p = " + r );
r = p << 2; /* Binary representation 240 = 1111 0000 */
System.out.println("p << 2 = " + r );
r = p >> 2; /* Binary representation 15 = 1111 */
System.out.println("p >> 2 = " + r );
r = p >>> 2; /* Binary representation 15 = 0000 1111 */
System.out.println("p >>> 2 = " + r );
}
}
This would produce the following result:
p & q = 12
p | q = 61
p ^ q = 49
~p = -61
p << 2 = 240
p >> 15
p >>> 15
Operators Precedence and Associativity
.
Every operator has a precedence and associativity associated with it. Precedence of oper-
ators is used in determining the sequence of operators for evaluating an expression in case
expression has a number of operators. In an expression, the operators having higher pre-
cedence are evaluated first.
Associativity is the concept for determining the evaluation order of operators when there
are multiple operators with same precedence then associative determines either to be eval-
uated from left to right or right to left.
