In Java, the values() method of the TreeMap class is present inside java.util package which is used to create a collection out of the values of the map. It basically returns a Collection view of the values in the TreeMap.
--> java.util package
--> TreeMap class
--> values() Method
Syntax:
Tree_Map.values()
Return Type: A collection view containing all the values of the map.
Now we will be proposing different sets to illustrate values() method as listed:
Example 1: Mapping String Values to Integer Keys
Java
// Java Program to illustrate values() Method
// of TreeMap class
// Importing required classes
import java.util.*;
// Main class
public class GFG {
// Main driver method
public static void main(String[] args)
{
// Creating an empty TreeMap by
// declaring object of integer, string pairs
TreeMap<Integer, String> tree_map
= new TreeMap<Integer, String>();
// Mapping string values to int keys
// using put() method
tree_map.put(10, "Geeks");
tree_map.put(15, "4");
tree_map.put(20, "Geeks");
tree_map.put(25, "Welcomes");
tree_map.put(30, "You");
// Printing the elements of TreeMap
System.out.println("Initial Mappings are: "
+ tree_map);
// Getting the set view of values
// using values() method
System.out.println("The collection is: "
+ tree_map.values());
}
}
Initial Mappings are: {10=Geeks, 15=4, 20=Geeks, 25=Welcomes, 30=You}
The collection is: [Geeks, 4, Geeks, Welcomes, You]
Example 2: Mapping Integer Values to String Keys.
Java
// Java Program to Illustrate values() method
// of TreeMap class
// Importing required classes
import java.util.*;
// Main class
public class GFG {
// Main driver method
public static void main(String[] args)
{
// Creating an empty TreeMap by
// declaring object of string, integer pairs
TreeMap<String, Integer> tree_map
= new TreeMap<String, Integer>();
// Mapping int values to string keys
// using put() method
tree_map.put("Geeks", 10);
tree_map.put("4", 15);
tree_map.put("Geeks", 20);
tree_map.put("Welcomes", 25);
tree_map.put("You", 30);
// Printing the elements of TreeMap
System.out.println("Initial Mappings are: "
+ tree_map);
// Getting the set view of values
// using values() method
System.out.println("The collection is: "
+ tree_map.values());
}
}
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.
