What is Java Operator Precedence |
|
|
Java operator precedence is how Java determines which operator to evaluate first.
In this chart, operator precedence is displayed from highest precedence to lowest precedence.

Notes:
- Expressions inside parentheses are evaluated first
- Nested parentheses are evaluated from the innermost parentheses to the outermost parenthesis.
- Operators in the same row in the chart have equal precedence.
