The following program demonstrates the use of the shift operators:
The output of the preceding program is as follows:
Enter a number
4
Using different shift operators, we get the following result:
1. >> 2 : 1
2. << 3 : 32
3. >>> 4 : 0
7.3 PRECEDENCE OF OPERATORS
The precedence of operators determines the order in which the operators are going to be executed in an expression.
The following table shows the precedence of operators in Java, the higher an operator appears in the table, the higher its
precedence.
S.No. Operators Precedence
1 postfix unary cal++, cal--
2 unary including prefix, logical NOT ++cal, --cal, +cal, -cal, ~, !
3 multiplication, division and modulus *, /, %
4 addition and subtraction +, -
5 Shift <<, >>, >>>
6 Relational <, >, <=, >=
7 equality, non-equality ==, !=
8 bitwise AND &
