ArrayList size can change during running time ArrayList can be defined as: ArrayList a = new ArrayList(); ArrayList can be defined as: ArrayList cList = new ArrayList(); Number of objects of an ArrayList x can be obtain using. x.length(); To replace the second object in ArrayList x, we can use: x.dd(1, obj2) To remove the last object of ArrayList x, we can use: x.remove(x.size()-1); If the objects type (for example Point) override the equals method, then the ArrayList of Points pList.contains(pl) will return true if there is a Point object in the ArrayList that has same values of pl
