2. Iterate ArrayList Elements

Write a Java program to iterate through all elements in an array list..

Pictorial Presentation:

Sample Solution:-

Java Code:

import java.util.*;
  public class Exercise2 {
  public static void main(String[] args) {
  // Creae a list and add some colors to the list
  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");
  // Print the list
  for (String element : list_Strings) {
    System.out.println(element);
    }
 }
}

Sample Output:

Red                                                                    
Green                                                                  
Orange                                                                 
White                                                                  
Black
