Reports declarations of equal() with a single parameter. Normally, this is a typo and equals() is actually intended.

A quick-fix is suggested to rename the method to equals.

Example:


  class Main {
    public boolean equal(Object obj) {
      return true;
    }
  }

After the quick-fix is applied:


  class Main {
    public boolean equals(Object obj) {
      return true;
    }
  }
