I am new to java and was wondering how to override an equals method. I was assigned 'Override the equals-method (from Object) so that it returns true for two objects that are logically equivalent based on the state of all of their instance variables.' I have no idea to go about this. I believe it starts with:

public boolean equals(Object object){
 if (variableA = variable){
      return true;
} else {
      return false;
}
