SortedMap values() method in Java with Examples

Last Updated : 26 Nov, 2018

The

values() method

SortedMap interface

in Java is used to create a collection out of the values of the map. It basically returns a Collection view of the values in the Map.

Syntax:

SortedMap.values()

Parameters:

The method does not accept any parameters.

Return Value:

The method is used to return a collection view containing all the values of the map. Below programs are used to illustrate the working of above method:

Program 1:

Mapping String Values to Integer Keys.

Java


 // Java code to illustrate the values() method

import java.util.*;

public class SortedMapDemo {
    public static void main(String[] args)
    {

        // Creating an empty TreeMap
        SortedMap<Integer, String>
            sotree_map = new TreeMap<Integer, String>();

        // Mapping string values to int keys
        sotree_map.put(10, "Geeks");
        sotree_map.put(15, "4");
        sotree_map.put(20, "Geeks");
        sotree_map.put(25, "Welcomes");
        sotree_map.put(30, "You");

        // Displaying the TreeMap
        System.out.println("Initial Mappings are: "
                           + sotree_map);

        // Using values() to get the set view of values
        System.out.println("The collection is: "
                           + sotree_map.values());
    }
}

Output:

Initial Mappings are: {10=Geeks, 15=4, 20=Geeks, 25=Welcomes, 30=You}
The collection is: [Geeks, 4, Geeks, Welcomes, You]

Program 2:

Mapping Integer Values to String Keys.

Java


 // Java code to illustrate the values() method

import java.util.*;

public class SortedMapDemo {
    public static void main(String[] args)
    {

        // Creating an empty TreeMap
        SortedMap<String, Integer>
            sotree_map = new TreeMap<String, Integer>();

        // Mapping int values to string keys
        sotree_map.put("Geeks", 10);
        sotree_map.put("4", 15);
        sotree_map.put("Geeks", 20);
        sotree_map.put("Welcomes", 25);
        sotree_map.put("You", 30);

        // Displaying the TreeMap
        System.out.println("Initial Mappings are: "
                           + sotree_map);

        // Using values() to get the set view of values
        System.out.println("The collection is: "
                           + sotree_map.values());
    }
}

Output:

Initial Mappings are: {4=15, Geeks=20, Welcomes=25, You=30}
The collection is: [15, 20, 25, 30]

Note:

The same operation can be performed with any type of Mappings with variation and combination of different data types.
