Class AvoidNoArgumentSuperConstructorCallCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable
    public final class AvoidNoArgumentSuperConstructorCallCheck
extends AbstractCheck

    Checks if call to superclass constructor without arguments is present. Such invocation is redundant because constructor body implicitly begins with a superclass constructor invocation super(); See specification for detailed information.

    To configure the check: 

     <module name="AvoidNoArgumentSuperConstructorCall"/>

    Example of violations 

     class MyClass extends SomeOtherClass {
     MyClass() {
         super(); // violation
     }

     MyClass(int arg) {
         super(arg); // OK, call with argument have to be explicit
     }

     MyClass(long arg) {
         // OK, call is implicit
     }
 }
