Java ArrayList

This is a library that implements Generics as an List

Example

import java.util.ArrayList
 
public class Driver {
	public static void main(String[] args){
		ArrayList<String> mylist = new ArrayList<String>();
		mylist.add("abc"); // adding "abc"
		System.out.println(mylist.contains("abc")); //true
	}
}

Methods

.contains()

This will use the datatypes, Java .equals() method to check, so make sure to overwrite this for custom classes.
