Java Program to Develop a List Interfaces

by

Aim:

Develop a java Programming was Collections of List Interfaces.

Procedure:

  • Step 1: Open a New Java Application on Netbeans Editor.
  • Step 2: Open Netbeans Ide, Choose File new Project.
  • Step 3: New Open a New Project and Choose a Java Application.
  • Step 4: Create a Java File Performing List Such as Array List and Linked List.
  • Step 5: Run the Index Page and Verify the Result Page.
  • Step 6: Save the Project (Ctrl+s).
  • Step 7: Run the Project (F5).

Program:

import java.util.*;
import java.lang.*;
public class list
{
public static void main(String[] args)
{
 ArrayList<String>a=new ArrayList<String>();
 a.add("java");
 a.add("visual");
 a.add("dbms");
 a.add("multi");
 a.add("visual");
 System.out.println("ArrayList"+a);
 System.out.println("ArrayList"+a.indexOf("java"));
 a.add(2,"CSHARP");
 System.out.println("Arraylist to"+a);
 String b=a.get(2);
 System.out.println("array list"+a.lastIndexOf("visual"));
 System.out.println("array list"+b);
 System.out.println("remove elements"+a.remove(3));
 System.out.println("after removing the element"+a); 
LinkedList<String>list=new LinkedList();
 list.add("W");
 list.add("H");
 list.add("T");
 list.add("E");
 System.out.println("the original content is"+list);
 list.remove("W");
 System.out.println("the remove content is"+list);
 list.addLast("H");
 list.addFirst("A");
 System.out.println("the add first and last content is"+list);
 String b1=list.getFirst();
 String c1=list.getLast();
 System.out.println("the original get first element is="+b1);
 System.out.println("the original get last element is="+c1);
 list.removeFirst();
 list.removeLast();
 System.out.println("the remove first and last element is"+list);
}
public list()
{
}
}
