Collections Class synchronizedSortedMap() method

• synchronizedSortedMap() method is available in java.util package.
• synchronizedSortedMap() method is used to return the synchronized view of the given sorted map (sm).
• synchronizedSortedMap() method is a static method, it is accessible with the class name and if we try to access the method with the class object then also we will not get any error.
• synchronizedSortedMap() method does not throw an exception at the time of returning synchronized sorted map.

Syntax:

    public static SortedMap synchronizedSortedMap(SortedMap sm);

Parameter(s):

• SortedMap sm – represents the sorted map to be viewed in synchronized sorted map.

Return value:

The return type of this method is SortedMap, it returns synchronized view of the given sorted map.

Example:

// Java program to demonstrate the example 
// of SortedMap synchronizedSortedMap() method 
// of Collections

import java.util.*;

public class SynchronizedSortedMapOfCollections {
    public static void main(String args[]) {
        // Instantiates a sorted map object
        SortedMap < Integer, String > tm = new TreeMap < Integer, String > ();

        // By using put() method is to add
        // objects in a treemap 
        tm.put(10, "C");
        tm.put(20, "C++");
        tm.put(30, "JAVA");
        tm.put(40, "PHP");
        tm.put(50, "SFDC");

        // Display TreeMap
        System.out.println("TreeMap: " + tm);

        // By using synchronizedSortedMap() method is to
        // represent the treemap in synchronized view
        tm = Collections.synchronizedSortedMap(tm);

        // Display Synchronized SortedMap
        System.out.println("Collections.synchronizedSortedMap(tm): " + tm);
    }
}

Output

TreeMap: {10=C, 20=C++, 30=JAVA, 40=PHP, 50=SFDC}
Collections.synchronizedSortedMap(tm): {10=C, 20=C++, 30=JAVA, 40=PHP, 50=SFDC}
