Java Program to get maximum value with Comparator
First, declare an integer array and add some elements −
Integer arr[] = { 40, 20, 30, 10, 90, 60, 700 };Now, convert the above array to List −
List list = Arrays.asList(arr);
Now, use Comparator and the reverseOrder() method. Using min() will eventually give you the minimum value, but with reverseOrder(), it reverses the result −
Comparator comp = Collections.reverseOrder();
System.out.println("Maximum element = "+Collections.min(list, comp));Example
import java.util.Arrays;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
public class Demo {
@SuppressWarnings("unchecked")
public static void main(String args[]) {
Integer arr[] = { 40, 20, 30, 10, 90, 60, 70 };
List list = Arrays.asList(arr);
Comparator comp = Collections.reverseOrder();
System.out.println("Maximum element = "+Collections.min(list, comp));
}
}Output
Maximum element = 700
