Using unmodifiable list Java 9

package test;package test;
import java.util.Collections;import java.util.Iterator;import java.util.List;
public class listtest {
public static void main(String[] args) { // TODO Auto-generated method stub
List im=List.of(“one”,”two”,”three”); List imlist=Collections.unmodifiableList(im); imlist.add(“four”); Iterator itr=imlist.iterator(); while(itr.hasNext()) { System.out.println(itr.next()); } }
}

In this case if you try to add new number in list this will result in java.lang.UnsupportedOperationException
