The checkedSortedSet() method of java.util.Collections class is used to return a dynamically typesafe view of the specified sorted set.
The returned sorted set will be serializable if the specified sorted set is serializable.
Since null is considered to be a value of any reference type, the returned sorted set permits insertion of null elements whenever the backing sorted set does.
Syntax:
public static SortedSet checkedSortedSet(SortedSet s, Class type)
Parameters: This method takes the following argument as a parameter:
- s – the sorted set for which a dynamically typesafe view is to be returned
- type – the type of element that s is permitted to hold
Return Value: This method returns a dynamically typesafe view of the specified sorted set.
Below are the examples to illustrate the checkedSortedSet() method
Example 1:
// Java program to demonstrate // checkedSortedSet() method // for String value import java.util.*;
public class GFG1 {
public static void main(String[] argv)
throws Exception
{
try {
// creating object of SortedMap<String>
SortedSet<String> sset = new TreeSet<String>();
// Adding element to smap
sset.add( "Ram" );
sset.add( "Gopal" );
sset.add( "Verma" );
// printing the sorted set
System.out.println( "Sorted Set: " + sset);
// create typesafe view of the specified set
// using checkedSortedSet() method
SortedSet<String>
tsset = Collections
.checkedSortedSet(sset, String. class );
// printing the typesafe view of specified set
System.out.println( "Typesafe view of sorted set: \n"
+ tsset);
}
catch (IllegalArgumentException e) {
System.out.println( "Exception thrown : " + e);
}
}

Sorted Set: [Gopal, Ram, Verma] Typesafe view of sorted set: [Gopal, Ram, Verma]
Example 2:
// Java program to demonstrate // checkedSortedSet() method // for Integer value import java.util.*;
public class GFG1 {
public static void main(String[] argv) throws Exception
{
try {
// creating object of SortedSet<Integer>
SortedSet<Integer> sset = new TreeSet<Integer>();
// Adding element to smap
sset.add( 20 );
sset.add( 30 );
sset.add( 40 );
// printing the sorted set
System.out.println( "Sorted Set: " + sset);
// create typesafe view of the specified set
// using checkedSortedSet() method
SortedSet<Integer> tsset = Collections.checkedSortedSet(sset, Integer. class );
// printing the typesafe view of specified set
System.out.println( "Typesafe view of sorted set: \n"
+ tsset);
}
catch (IllegalArgumentException e) {
System.out.println( "Exception thrown : " + e);
}
}
