Java Operators

Operators are used to perform operations on variables and values.

In the example on the right side, we use the + operator to add together two values.

Although the + operator is often used to add together two values, like in the example above, it can also be used to add together a variable and a value, or a variable and another variable.

Java divides the operators into the following groups:

  • Arithmetic operators
  • Assignment operators
  • Comparison operators
  • Logical operators
  • Bitwise operators

Arithmetic Operators

Arithmetic operators are used to performing common mathematical operations.

Assignment Operators

Assignment operators are used to assign values to variables.

Comparison Operators

Comparison operators are used to compare two values. This is important in programming, because it helps us to find answers and make decisions.

Logical Operators

You can also test for true or false values with logical operators.
