Java Operators

Operators are symbols that used to perform operations on variables and values.

Java provides a rich set of operators that can be divided into the following types:

• Arithmetic Operators

• Relational Operators

• Bitwise Operators

• Logical Operators

• Assignment Operators

• Misc Operators

Arithmetic operators

These are used to performing common mathematical operations on variables and data.

Example: Arithmetic Operators

Note for the division operator: If the division operator is used with two integers, then the resulting quotient will also be an integer. And, if one of the operands is a floating-point number, the result will also be in floating-point.

Example: / with floating-point number

Relational (Comparison) Operators

These are used to check the relationship between two operands.

Example: Comparison Operators

Note: Relational operators are used in decision making and loops.

Bitwise Operators

These can be applied to the integer types, long, int, short, char, and byte.

Example: Bitwise Operators

Logical Operators

These are used to determine the logic between variables or values

Example: Logical оperators

Assignment Operators

These are used to assign values to variables

Example: Assignment оperators

Misc Operators

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

Instance of Operator

This operator is used only for object reference variables. The operator checks whether the object is of a particular type (class type or interface type). instance of operator is written as − (Object reference variable) instance of (class/interface type)

If the object referred by the variable on the left side of the operator passes the IS-A check for the class/interface type on the right side, then the result will be true.
