Get Synchronized Map from Java TreeMap example

This java example shows how to get a synchronized Map from Java TreeMap using synchronizedMap method of Collections class.

import java.util.Collections;
import java.util.Map;
import java.util.TreeMap;

public class GetSynchronizedMapFromTreeMapExample {

 public static void main(String[] args) {

  // create TreeMap object

  TreeMap treeMap = new TreeMap();

  /**
   * Java TreeMap is NOT synchronized. To get synchronized
   * Map from TreeMap use static void synchronizedMap(Map map)
   * method of Collections class.
   **/

  Map map = Collections.synchronizedMap(treeMap);

  /**
   * Use this map object to prevent any unsynchronized access
   * to original TreeMap object.
   **/
