Find maximum element of HashSet in Java
To get the maximum element of HashSet, use the Collections.max() method.
Declare the HashSet −
Set<Integer> hs = new HashSet<Integer>();
Now let us add the elements −
hs.add(29); hs.add(879); hs.add(88); hs.add(788); hs.add(456);
Let us now get the maximum element −
Object obj = Collections.max(hs);
The following is an example to find maximum element of HashSet −
Example
import java.util.*; public class Demo { public static void main(String args[]) { // create hash set Set<Integer> hs = new HashSet<Integer>(); hs.add(29); hs.add(879); hs.add(88); hs.add(788); hs.add(456); System.out.println("Elements in set = "+hs); // finding maximum element Object obj = Collections.max(hs); System.out.println("Maximum Element = "+obj); } }
Output
Elements in set = [788, 88, 456, 29, 879] Maximum Element = 879
