The synchronizedSortedSet() method of java.util.Collections class is used to return a synchronized (thread-safe) sorted set backed by the specified sorted set. In order to guarantee serial access, it is critical that all access to the backing sorted set is accomplished through the returned sorted set (or its views).
Syntax:
public static <T> SortedSet<T> synchronizedSortedSet(SortedSet<T> s)
Parameters: This method takes the sorted set as a parameter to be “wrapped” in a synchronized sorted set.
Return Value: This method returns a synchronized view of the specified sorted set.
Below are the examples to illustrate the synchronizedSortedSet() method
Example 1:
// Java program to demonstrate // synchronizedSortedSet() method // for <String> Value import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating object of SortedSet<String> SortedSet<String> set = new TreeSet<String>(); // populate the set set.add( "A" ); set.add( "B" ); set.add( "C" ); set.add( "D" ); // printing the Collection System.out.println( "Sorted Set : " + set); // create a synchronized sorted set SortedSet<String> sorset = Collections .synchronizedSortedSet(set); // printing the set System.out.println( "Sorted set is : " + sorset); } catch (IllegalArgumentException e) { System.out.println( "Exception thrown : " + e); } } } |
Sorted Set : [A, B, C, D] Sorted set is : [A, B, C, D]
Example 2:
// Java program to demonstrate // synchronizedSortedSet() method // for <Integer> Value import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating object of SortedSet<String> SortedSet<Integer> set = new TreeSet<Integer>(); // populate the set set.add( 10 ); set.add( 20 ); set.add( 30 ); set.add( 40 ); // printing the Collection System.out.println( "Sorted Set : " + set); // create a synchronized sorted set SortedSet<Integer> sorset = Collections .synchronizedSortedSet(set); // printing the set System.out.println( "Sorted set is : " + sorset); } catch (IllegalArgumentException e) { System.out.println( "Exception thrown : " + e); } } } |
Sorted Set : [10, 20, 30, 40] Sorted set is : [10, 20, 30, 40]
