Find minimum element of HashSet in Java
To get the minimum element of HashSet, use the Collections.min() 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 minimum element −
Object obj = Collections.min(hs);
The following is an example to find the minimum 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 minimum element
Object obj = Collections.min(hs);
System.out.println("Minimum Element = "+obj);
}
}Output
Elements in set = [788, 88, 456, 29, 879] Minimum Element = 29
