Java Utility Library

Java LinkedHashMap - values() Method

The java.util.LinkedHashMap.values() method returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa.

Syntax

public Collection<V> values()

Here, V is the type of value maintained by the container.

Parameters

No parameter is required.

Return Value

Returns a view of the values contained in this map.

Exception

Example:

In the example below, the java.util.LinkedHashMap.values() method returns a view of the values contained in the given LinkedHashMap.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a linkedhashmap
    LinkedHashMap<Integer, String> MyMap = new LinkedHashMap<Integer, String>();

    //populating the map
    MyMap.put(101, "John");
    MyMap.put(102, "Marry");
    MyMap.put(103, "Kim");
    MyMap.put(104, "Jo");
    MyMap.put(105, "Sam");

    //printing the content of the map
    System.out.println("MyMap contains: " + MyMap);

    //creating a Collection view
    Collection<String> ValueView = MyMap.values();

    //printing the Collection view
    System.out.println("ValueView contains: " + ValueView);
  }
}

The output of the above code will be:

MyMap contains: {101=John, 102=Marry, 103=Kim, 104=Jo, 105=Sam}
ValueView contains: [John, Marry, Kim, Jo, Sam]
