SortedMap values() method in Java with Examples

Last Updated : 26 Nov, 2018

The values() method of 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.
