Let's create a simple example of ArrayList class define with empty ArrayList of String and add elements later.Tags: base64 | byte array | java string | java.io | string Kotlin ArrayList Example 1- empty ArrayList It does nothing in this ArrayList implementation. It is used to returns a string representation of the object. It is used to return new array of type Array with the elements of this collection. It is used to replaces the element from the specified position from current list with the specified element. Its remove the range of elements starting from startIndex to endIndex in which endIndex is not includes. Open fun removeRange(startIndex: Int, endIndex: Int) It is used to remove the specific index element from the list.
