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}
