The last() method of SortedSet interface in Java is used to return the last i.e., the highest element currently in this set.
Syntax:
E last()
Where, E is the type of element maintained by this Set.
Parameters: This function does not accepts any parameter.
Return Value: It returns the last or the highest element currently in the set.
Exceptions: It throws NoSuchElementException, if the set is empty.
Below programs illustrate the above method:
Program 1:
// A Java program to demonstrate
// working of SortedSet
import java.util.SortedSet;
import java.util.TreeSet;
public class Main {
public static void main(String[] args)
{
// Create a TreeSet and inserting elements
SortedSet<Integer> s = new TreeSet<>();
// Adding Element to SortedSet
s.add(1);
s.add(5);
s.add(2);
s.add(3);
s.add(9);
// Returning the lowest element from set
System.out.print("Greatest element in set is : "
+ s.last());
}
}
Greatest element in set is : 9
Program 2:
// Program to illustrate the last()
// method of SortedSet interface
import java.util.SortedSet;
import java.util.TreeSet;
public class GFG {
public static void main(String args[])
{
// Create an empty SortedSet
SortedSet<Integer> s = new TreeSet<>();
// Trying to access element from
// empty set
try {
s.last();
}
catch (Exception e) {
// throws NoSuchElementException
System.out.println("Exception: " + e);
}
}
}
Exception: java.util.NoSuchElementException
