Structure of the Problem Requirements
In this problem we will learn how to store any value in ArrayList in Java. ArrayList is same like Arrays in programming but a little bit mature then Arrays :). ArrayList exist in java.util.ArrayList class . we declare an object of this class and then pass the different value to it to store them . This is very simple example which will be more clear when you practice it and see the output at the end of the program.

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class Array_List {
public static void main (String [] args )
{
int size = 0;
Scanner input = new Scanner (System.in);
ArrayList <Integer> num = new ArrayList <Integer> ();
for (int i= 0; i<5;i++)
{
System.out.println(" Enter Your Number ");
num.add(input.nextInt());
}
System.out.println(" Your Array list contain : ");
System.out.println(num);
}
}
