com.puppycrawl.tools.checkstyle.checks.coding.DefaultComesLastCheck

All Implemented Interfaces:

Configurable, Contextualizable

public class DefaultComesLastCheck
extends AbstractCheck

Check that the default is after all the cases in a switch statement.

Rationale: Java allows default anywhere within the switch statement. But if it comes after the last case then it is more readable.

An example of how to configure the check is:

 <module name="DefaultComesLast"/>
