Alright, join or login here.This video shows an example of ArrayList in Java. We first see how to use an ArrayList with a for each loop and then use a JOptionPane.showInputDialog() to take user input to enter a bunch of numbers. We store these numbers in an ArrayList capable of storing only Integer values and then find the minimum, maximum and average of these numbers. We finally display the results to the user using the JOptionPane.showMessageDialog() method.
