Java Collections checkedSortedSet() Method

The checkedSortedSet() is an inbuilt method of Java Collections class. This method is used to get a dynamically typesafe view of the specified sorted set.

Syntax

Following is the declaration of checkedSortedSet() method:

Parameter

Parameter	Description	Required/Optional
s	It is the sorted set for which a dynamically typesafe view is to be returned.	Required
type	It is the type of element that s is permitted to hold.	Required

Returns

The checkedSortedSet() method automatically returns a dynamically typesafe view of the specified Sorted Set in the ascending order.

Exceptions

ClassCastException

Compatibility Version

Java 1.5 and above

Example 1

  import java.util.*;  public class CollectionsCheckedSortedSetExample1 {  public static void main(String[] args) {  TreeSet<String> set = new TreeSet<String>();  //Insert values in the Set  set.add(“TutorAspire”);  set.add(“Hindi100”);  set.add(“SSSIT”);  set.add(“JavaTraining”);        //Get type safe view of the Set                System.out.println(“Type safe view of the Sorted Set is: “+Collections.checkedSortedSet(set,String.class));        }  }  

Test it Now

Output:

Type safe view of the Set is: [Hindi100, TutorAspire , JavaTraining, SSSIT]

Example 2

  import java.util.*;  public class CollectionsCheckedSortedSetExample2 {  public static void main(String[] args) {  TreeSet set = new TreeSet<>();  //Insert values in the Set  set.add(1100);  set.add(100);  set.add(500);  set.add(200);        //Get type safe view of the Set    SortedSet TypeSafeSet;  TypeSafeSet = Collections.checkedSortedSet(set,Integer.class);        System.out.println(“The view of the Sorted Set is: “+TypeSafeSet);        }  }  

Test it Now

Output:

The view of the Sorted Set is: [100, 200, 500, 1100]

Example 3

  import java.util.*;  public class CollectionsCheckedSortedSetExample3 {  public static void main(String[] args) {  SortedSet set = new TreeSet<>();              set = Collections.checkedSortedSet(set, Integer.class);              set.add(1100);              set.add(5000);                     set.add(800);              System.out.println(“Dynamic type safe view of Sorted Set is: “+set);              Set set2 = set;              set2.add(“SSSIT.COM”);              System.out.println(set2);        }  }  

Test it Now

Output:

Dynamic type safe view of Sorted Set is: [800, 1100, 5000]  Exception in thread "main" java.lang.ClassCastException: Attempt to insert class java.lang.String element into collection with element type class java.lang.Integer  at java.base/java.util.Collections$CheckedCollection.typeCheck(Collections.java:3038)  at java.base/java.util.Collections$CheckedCollection.add(Collections.java:3081)  at myPackage.CollectionCheckedSortedSetExample3.main(CollectionCheckedSortedSetExample3.java:12)
