NavigableMap is used for convenient navigation methods like lowerKey, floorKey, ceilingKey, and higherKey, along with this popular navigation method. It will take key-value pair as input
We can create a navigable map by using the following syntax:
NavigableMap<key_datatype, value_datatype> data= new TreeMap<key_datatype, value_datatype>();
where
- data is the input data.
- key_datatype refers to the key type element.
- value_datatype refers to the value type element.
synchronizedNavigableMap() Method will return the synchronized, which is a thread-safe navigable map backed by the specified navigable map.
Syntax:
public static <Key,Value> NavigableMap<K,V> synchronizedNavigableMap(NavigableMap<Key,Value> data)
where data is the navigable map which will be wrapped into a synchronized navigable map.
Return Type: The synchronizedNavigableMap() method returns a synchronized view of the specified Navigable Map.
Example 1: Create a synchronized navigable map using string elements
Java
import java.util.*;  public class GFG1 {    // main method    public static void main(String[] args)    {        // create a NavigableMap        NavigableMap<String, String> data            = new TreeMap<String, String>();          // add data values        data.put("1", "java");        data.put("2", "python");        data.put("3", "php");        data.put("4", "html/js");          // create synchronized NavigableMap from the created        // map(data)        Map<String, String> syn            = Collections.synchronizedNavigableMap(data);        System.out.println(syn);    }} |
Output
{1=java, 2=python, 3=php, 4=html/js}
Example 2:
Java
import java.util.*;  public class GFG1 {    // main method    public static void main(String[] args)    {        // create a NavigableMap        NavigableMap<Integer, Integer> data            = new TreeMap<Integer, Integer>();          // add data values        data.put(1, 34);        data.put(2, 45);        data.put(3, 74);        data.put(4, 41);        data.put(5, 4);        data.put(6, 40);          // create synchronized NavigableMap         // from the created map(data)        Map<Integer, Integer> syn            = Collections.synchronizedNavigableMap(data);        System.out.println(syn);    }} |
Output
{1=34, 2=45, 3=74, 4=41, 5=4, 6=40}
