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 elemnet 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 elemnet 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); } } } |
Sorted Set: [20, 30, 40] Typesafe view of sorted set: [20, 30, 40]
