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("JavaTpoint");
		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, JavaTpoint, JavaTraining, SSSIT]

Example 2

import java.util.*;
public class CollectionsCheckedSortedSetExample2 {
	public static void main(String[] args) {
		TreeSet<Integer> 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<Integer> 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<Integer> 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]
