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:
import java.util.*;
public class GfG {
public static void main(String[] args)
{
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().
import java.util.*;
public class GfG {
public static void main(String[] args)
{
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}
