Example 1

  import java.util.*;  public class CollectionsUnmodifiableSortedSetExample1 {  public static void main(String[] args) {        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 Unmodifiable sorted set        SortedSet<String> set2 = Collections.unmodifiableSortedSet(set);        System.out.println(“Unmodifiable Sorted set is :”+set2);        set.add(“Google”);        System.out.println(“Unmodifiable Sorted set after modify is:”+set2);        }  }

Output:

Unmodifiable Sorted set is :[Facebook, Instagram, Twitter, Whatsapp]  Unmodifiable Sorted set after modify is:[Facebook, Google, Instagram, Twitter, Whatsapp]

Example 2

  import java.util.*;  public class CollectionsUnmodifiableSortedSetExample2 {  public static void main(String[] args) {  SortedSet<Integer> set = new TreeSet<>();              Collections.addAll(set, 1, 9, 7);              System.out.println(“Original Set: ” + set);              SortedSet<Integer> set2 = Collections.unmodifiableSortedSet(set);              System.out.println(“Unmodifiable Sorted Set: ” + set2);              //Modifying the original Set              set.add(10);              System.out.println(“Unmodifiable Sorted Set: ” + set2);        }  }  

Test it Now

Output:

Original Set: [1, 7, 9]  Unmodifiable Sorted Set: [1, 7, 9]  Unmodifiable Sorted Set: [1, 7, 9, 10]

Example 3

  import java.util.*;  public class CollectionsUnmodifiableSortedSetExample3 {  public static void main(String[] args) {  SortedSet<Integer> set = new TreeSet<>();              Collections.addAll(set, 1, 4, 7);              System.out.println(“Original Set: ” + set);              SortedSet<Integer> set2 = Collections.unmodifiableSortedSet(set);              set2.add(10);        }  }  

Test it Now

Output:

Original Set: [1, 4, 7]  Exception in thread "main" java.lang.UnsupportedOperationException  at java.base/java.util.Collections$UnmodifiableCollection.add(Collections.java:1056)  at myPackage.CollectionsUnmodifiableSortedSetExample3.main(CollectionsUnmodifiableSortedSetExample3.java:9)
