重载一个方法,仅仅调用了超类的相同方法,没有执行其他操作,是无用并且误导的。

如下代码演示了这个规则:

public void doSomething() {                     // Non-Compliant
  super.doSomething();
}

@Override
public boolean isLegal(Action action) {         // Non-Compliant
  return super.isLegal(action);
}

@Override
public boolean isLegal(Action action) {         // Compliant - not simply forwarding the call
  return super.isLegal(new Action(/* ... */));
}

@Id
@Override
public int getId() {                            // Compliant - there is annotation different from @Override
  return super.getId();
}
