SortedMap put() method in Java with Examples

Last Updated : 30 Sep, 2019

The put() method of SortedMap interface in Java is used to associate the specified value with the specified key in this map.

Syntax:

V put(K key,
    V value)

Parameters: This method has two arguments:

key: which is the left argument and
value: which is the corresponding value of the key in the map.

Returns: This method returns previous value associated with the key if present, else return -1.

Note: The put() method in SortedMap is inherited from the Map interface in Java.

Below programs illustrate the implementation of int put() method:

Program 1:

// Java code to show the implementation of 
// put method in SortedMap interface 
  
import java.util.*; 
  
public class GfG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
  
        // Initializing a SortedMap 
        SortedMap<Integer, String> map 
            = new TreeMap<>(); 
  
        map.put(1, "One"); 
        map.put(3, "Three"); 
        map.put(5, "Five"); 
        map.put(7, "Seven"); 
        map.put(9, "Ninde"); 
  
        System.out.println(map); 
    } 
} 

Output:

{1=One, 3=Three, 5=Five, 7=Seven, 9=Ninde}

Program 2: Below is the code to show implementation of put().

// Java code to show the implementation of 
// put method in SortedMap interface 
  
import java.util.*; 
  
public class GfG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
  
        // Initializing a SortedMap 
        SortedMap<String, String> map 
            = new TreeMap<>(); 
  
        map.put("1", "One"); 
        map.put("3", "Three"); 
        map.put("5", "Five"); 
        map.put("7", "Seven"); 
        map.put("9", "Ninde"); 
  
        System.out.println(map); 
    } 
} 

Output:

{1=One, 3=Three, 5=Five, 7=Seven, 9=Ninde}
