Write a Java program to create an array list, add some colors (strings) and print out the collection.

Pictorial Presentation:

Sample Solution:-

Java Code:

import java.util.*;
public class Exercise1 {
  public static void main(String[] args) {
  List<String> list_Strings = new ArrayList<String>();
  list_Strings.add("Red");
  list_Strings.add("Green");
  list_Strings.add("Orange");
  list_Strings.add("White");
  list_Strings.add("Black");
  System.out.println(list_Strings);
 }
