Call super.toString in Subclasses

[Clashsoft]

Classes with a super class should call super.toString() in their own toString implementation.

Example:

class Person {
   String name;

   public String toString() {
      StringBuilder builder = new StringBuilder();
      builder.append(' ').append(this.name);
      return builder.substring(1);
   }
}

class Student extends Person {
   int studID;

   public String toString() {
      StringBuilder builder = new StringBuilder(super.toString()); // <-- super call
      builder.append(' ').append(this.name);
      return builder.toString(); // not using substring(1), since the builder no starts with space
   }
}

Good idea.
