Parameter name differs from parameter in overridden or overloaded method

Reports parameters whose names differ from the corresponding parameters of the methods they override or overload. While legal in Java, such inconsistent names may be confusing and decrease the documentation benefits of good naming practices.

Example:

  class Person {
    Person(String fullName) {}
  }
  class Child extends Person {
    Child(String name) { super(name); }
  }

After the quick-fix is applied:

  class Person {
    Person(String fullName) {}
  }
  class Child extends Person {
    Child(String fullName) { super(fullName); }
  }
