In Java, operators are special symbols that perform specific operations on one, two, or three operands, and then return a result.
There are several types of operators in Java:
- Arithmetic operators: These operators perform basic arithmetic operations such as addition, subtraction, multiplication, and division.
- Comparison operators: These operators compare two values and return a boolean value (true or false) based on the result of the comparison. Examples include
!=(not equal to),
>(greater than), and
- Logical operators: These operators perform logical operations such as AND, OR, and NOT.
- Bitwise operators: These operators perform bitwise operations on the individual bits of an integer value.
- Assignment operators: These operators are used to assign values to variables. The most common assignment operator is
=, which assigns a value to a variable.
- Ternary operator: This operator is a shorthand way of writing an if-else statement. It takes three operands and returns a value based on a boolean expression.
- Precedence and associativity: The order in which operators are evaluated is determined by their precedence and associativity. Operators with higher precedence are evaluated before operators with lower precedence, and operators with the same precedence are evaluated based on their associativity (either left-to-right or right-to-left).
It’s important to understand how these operators work in order to write correct and efficient Java code.
