- I have empty array,
- I create 2 variables that contains identical objects,
- I put a content of first variable to my array, using .add() method,
- I check if my array contains object from second variable or not, object that is identical as object from first variable,
I check it using .contains(Object o) method,
- Result is false.
- Why?
public boolean check() {
ArrayList<City> citiesList = new ArrayList<City>();
City city1 = new City("Warsaw");
City city2 = new City("Warsaw");
citiesList.add(city1);
return (citiesList.contains(city2));
}
