Answers Code

In this shot, we will discuss how to use the SortedMap.values() method in Java.

The SortedMap.values() method is present in the SortedMap interface inside the java.util package.

The SortedMap.values() method is used to obtain the set of values present in the key-value pairs in the SortedMap.

Parameter

The SortedMap.values() method doesn’t take any parameters.

Return

The SortedMap.values() method returns:

  • Set: Set of values present in the key-value pairs in the SortedMap.

Code

Let’s look at the code snippet.

import java.util.*;
class Main
{
public static void main(String[] args)
{
SortedMap<Integer, String> s = new TreeMap<Integer,String>();
s.put(2,"Welcome");
s.put(12,"to");
s.put(31,"the");
s.put(18,"world");
s.put(25,"of");
s.put(36,"java");
System.out.println("SortedMap mappings are: "+ s);
System.out.println("The values present in the SortedMap are " + s.values());
}
}
Using SortedMap.values() method in Java

Explanation

  • In line 1, we imported the required package.
  • In line 2, we made a Main class.
  • In line 4, we made a main function.
  • In line 6, we declared a SortedMap consisting of Integer type keys and String type values.
  • From lines 8 to 13, we inserted values in the Hashtable by using the TreeMap.put() method.
  • In line 15, we displayed the mappings present in the SortedMap.
  • In line 17, we used the SortedMap.values() method to obtain the set of values present in the key-value pairs in the SortedMap and displayed it.

In this way, we can use the SortedMap.values() method in Java.
