How to override equals method in Java

Question

I am trying to override equals method in Java. I have a class People which basically has 2 data fields name and age. Now I want to ove

Answer 1

@Override
public boolean equals(Object that){
  if(this == that) return true;//if both of them points the same address in memory

  if(!(that instanceof People)) return false; // if "that" is not a People or a childclass

  People thatPeople = (People)that; // than we can cast it to People safely

  return this.name.equals(thatPeople.name) && this.age == thatPeople.age;// if they have the same name and same age, then the 2 objects are equal unless they're pointing to different memory adresses
}
