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.
import java.util.*;
public class SortedMapDemo {
public static void main(String[] args)
{
SortedMap<Integer, String>
sotree_map = new TreeMap<Integer, String>();
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");
System.out.println("Initial Mappings are: "
+ sotree_map);
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.
import java.util.*;
public class SortedMapDemo {
public static void main(String[] args)
{
SortedMap<String, Integer>
sotree_map = new TreeMap<String, Integer>();
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);
System.out.println("Initial Mappings are: "
+ sotree_map);
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.
