Question

Java Framework Collection Assign.

Create a class called ArrayListExample

Create a ArrayList object called languageList which accept type of String

Add English, French, Italian and Arabic strings into languageList array object

Print languageList using Iterator object

Sort ArrayList object alphabetically

Print languageList using Iterator object

Solution will produce following:

1. ArrayListExample class
2. ArrayList object called languageList
3. ArrayListExampleTest class with main method

Answer 1

import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
//Create a class called ArrayListExample
public class ArrayListExample {
   public static void main(String[] args) {
//       Create a ArrayList object called languageList which accept type of String
       ArrayList<String> languageList = new ArrayList<String>();
//       Add English, French, Italian and Arabic strings into languageList array object
       languageList.add("English");
       languageList.add("French");
       languageList.add("Italian");
       languageList.add("Arabic");
      
       System.out.print("Before Sort\t:");
       // Looping ArrayList using Iterator
//       Print languageList using Iterator object
Iterator it = languageList.iterator();
while (it.hasNext())
System.out.print(it.next() + " ");
// Sort ArrayList object alphabetically
Collections.sort(languageList);
System.out.println();
System.out.print("After Sort\t:");
// Print languageList using Iterator object
// Looping ArrayList using Iterator
Iterator it2 = languageList.iterator();
while (it2.hasNext())
System.out.print(it2.next() + " ");
  
   }
}
