Java Switch

This lesson is part of Java · All levels

Summary

The switch is a branching alternative when checking one variable against many fixed values. Modern Java supports switch expression with arrows -> and default pieces that are no longer mandatory to use break. This approach makes code more concise and avoids unintended fall-throughs.

Key points

The switch is suitable for comparing one variable with many constant values.
Use arrows -> on the switch expression so you don't have to write break
The default block runs when there is no case that matches
The classic version uses cases, semicolons, and break to stop executions
