    public class MethodLengthCheck

extends Check

Checks for long methods.

Rationale: If a method becomes very long it is hard to understand. Therefore long methods should usually be refactored into several individual methods that focus on a specific task.

The default maximum method length is 150 lines. To change the maximum number of lines, set property max.

An example of how to configure the check is:

     <module name="MethodLength"/>

An example of how to configure the check so that it accepts methods with at most 60 lines is:

     <module name="MethodLength">
        <property name="max" value="60"/>
     </module>
