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
     }
 }
