List.contains Method

Visual Studio 2005

Checks if a List object contains a specific element.

Package: java.util

Assembly: vjslib (in vjslib.dll)

public abstract boolean contains(
    java.lang.Object e);



The element searched for in the List object.

true if the element was found; false otherwise.

In this example, you create and initialize a linked list object, and then you check to see if the list contains a specified element.

// list-cont1.jsl
// List.contains example

import java.util.*;

public class MyClass
    public static void main(String[] args)
        // Create a linked list object:
        LinkedList lList =  new LinkedList();

        // Add some elements:
        lList.add("My Node");
        lList.add("Your Node");
        lList.add(new Integer(55));

        // Check if "My Node" is in the list:
        if(lList.contains("My Node"))
                       "The object \"My Node\" is in the list.");

The object "My Node" is in the list.
