SortedMap put() method in Java with Examples
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}
