Operators in Java

Java Lecture

Java provides a rich set of operators to manipulate variables. We can divide Java operators into the groups.

In this section, you will learn how to use operators and the rules of precedence.

Operators are mainly symbols that is used to perform operations between two or more operands.

e.g: + - * /

We can divide Java operators into the following groups.

Arithmetic Operators
Relational Operators
Bitwise Operators
Logical Operators
Assignment Operators
Misc Operators

The Arithmetic Operators

Arithmetic operators are used in mathematical expressions in the same way that they are used in algebra. The following table lists the arithmetic operators

The Relational Operators

The Bitwise Operators

Bitwise Operators which can be applied to the integer types, long, int, short, char, and byte.

Bitwise operator works on bits and performs bit-by-bit operation.

Assume if a = 60 and b = 13 now in binary format they will be as follows

a = 0011 1100

b = 0000 1101

a&b = 0000 1100

a|b = 0011 1101

a^b = 0011 0001

~a = 1100 0011

The Logical Operators

The Assignment Operators

The Misc Operators

There are few other operators supported by Java Language.

Conditional Operator ( ? : )

Conditional operator is also known as the ternary operator. This operator consists of three operands and is used to evaluate Boolean expressions.

The goal of the operator is to decide, which value should be assigned to the variable. The operator is written as −

variable x = (expression) ? value if true : value if false
