![]() ![]() Output: ArrayList can now surely store upto 500 elements. ("ArrayList can now surely store upto 500 elements.") ensure that the ArrayList can hold upto 5000 elements using ensureCapacity() method MinCapacity, this method takes the desired minimum capacity as a parameter. It ensures that it can hold at least the number of elements specified by the minimum capacity argument. The ensureCapacity(int minCapacity) method is used to increase the capacity of ArrayList. You can read it with an example from here. toArray(T a) method : It is also used to convert the list to array but it takes parameter of array type. You can read it with an example from here.Ģ1. toArray() method: This method is used to convert ArrayList to Array. subList(int fromIndex, int toIndex) method: The subList() method returns a portion from the ArrayList that start from fromIndex and ends to toIndex. It takes only one argument that is a reference of Comparator. sort(Comparator c): By use of ArrayList.sort(Comparator c), we can sort the ArrayList. listIterator(int index): The listIterator(int index) method is used to return a list iterator over the elements in ArrayList starting at the specified position in the ArrayList. You can read it with an example from here.ġ7. listIterator(): The listIterator () method is used to return a list iterator over the elements in the ArrayList. You can read it with an example from here.ġ6. spliterator(): The spliterator() method returns an object Spliterator. You can read it with an example from here.ġ5. iterator(): The iterator() method is used to iterate the elements of an ArrayList. set(int index, E element): The set(int index, E element) method is used to replace the element at a particular index in the ArrayList with the specified element. How to replace element in an ArrayList?ġ3. lastIndexOf(Object o): The lastIndexOf(Object o) method is used to get the last index of the specified object. You can read it with an example from here.ġ2. index(object o): The index(object o) method is used to get the index of the specified object. ![]() How to get index of object in ArrayList java?ġ1. iterator(): The iterator() method is used to return an iterator over the elements in the ArrayList. You can read it with an example from here.ġ0. get(int index): The get(int index) method is used to get the element at the specified index in the ArrayList. ![]() How to access elements from an ArrayList?ĩ. removeIf(Predicate filter): The removeIf(Predicate filter) method is used to remove all elements from the ArrayList based on the predicate’s condition. You can read it with an example from here.Ĩ. remove(Collection c): The remove(Collection c) method is used to remove all the elements of the specified collection from the ArrayList. You can read it with an example from here.ħ. remove(int index): The remove(int index) method is used to remove the element at the specified index in the ArrayList. You can read it with an example from here.Ħ. remove(Object o): The remove(Object o) method is used to remove the first occurrence of the element from the ArrayList. How to remove elements from an ArrayList?ĥ. addAll(int index, Collection c): The addAll(int index, Collection c) is used to add the collection of elements at specified position in the ArrayList. You can read it with an example from here.Ĥ. addAll(Collection c): The addAll(Collection c) is used to add the collection of elements to the end of the ArrayList. You can read it with an example from here.ģ. add(int index, E e): The add(int index, E e) method is used to add the specified element at a specific position in the ArrayList. You can read it with an example from here.Ģ. add(E e): The add(E e) method is used to add the specified element e in the ArrayList. In this post, we will cover all the methods of ArrayList in java, and let’s see the java ArrayList methods with example. ![]() The ArrayList class provides a lot of Java ArrayList methods to operate the data of ArrayList. We have read how to create and initialize the ArrayList in java. ![]()
