Java Collections synchronizedSortedSet() Method

The synchronizedSortedSet() method of Java Collections class is used to get a synchronized (thread-safe) sorted set backed by the specified sorted set.

Syntax

Following is the declaration of synchronizedSortedSet() method:

Parameter

Parameter	Description	Required/Optional
s	It is the sorted set which will be wrapped in a synchronized sorted set.	Required

Returns

The synchronizedSortedSet() method returns a synchronized view of the specified Sorted Set.

Example 1

  import java.util.*;  public class CollectionsSynchronizedSortedSetExample1 {  public static void main(String[] args) {  //Create set        SortedSet<String> set = new TreeSet<String>();        //Add values in the set        set.add(“Facebook”);        set.add(“Twitter”);        set.add(“Whatsapp”);        set.add(“Instagram”);        //Create a synchronized sorted set        Set<String> synset = Collections.synchronizedSortedSet(set);        System.out.println(“Synchronized Sorted set is :”+synset);      }  }  

Test it Now

Output:

Synchronized Sorted set is :[Facebook, Instagram, Twitter, Whatsapp]

Example 2

  import java.util.*;  public class CollectionsSynchronizedSortedSetExample2 {  public static void main(String[] args) {  SortedSet<Integer> set = Collections.synchronizedSortedSet(new TreeSet<>());  set.add(101);  set.add(104);  set.add(103);  set.add(102);  set.add(105);  System.out.println(“Set after Synchronized sorted set-“);  //Using iterator must be synchronized manually  synchronized (set) {      Iterator<Integer> iterator = set.iterator();       while (iterator.hasNext()) {            Integer num = iterator.next();            System.out.println(num);          }      }            }  }  

Test it Now

Output:

Set after Synchronized sorted set-  101  102  103  104  105
