Create an ArrayList object.
Add elements to Arraylist
create object of method asObject obj = Collections.min(arrayList);
import java.util.ArrayList;
import java.util.Collections;
public class MinimumArrayListExample {
public static void main(String[] args) {
ArrayList arrayList = new ArrayList();
arrayList.add(new Integer("2356"));
arrayList.add(new Integer("5694"));
arrayList.add(new Integer("1025"));
arrayList.add(new Integer("3241"));
arrayList.add(new Integer("8924"));
Object obj = Collections.min(arrayList);
System.out.println("The Minimum Element of Java ArrayList is : " + obj);
}
}
