Example of Java Arraylist to Array
import java.util.ArrayList;
public class List1 {
public static void main(String[] args) {
int ar[]={444,222,333,111};
ArrayList list=new ArrayList();
list.add(ar[0]);
list.add(ar[1]);
list.add(ar[2]);
list.add(ar[3]);
Object obj[]=list.toArray();
for(Object x:obj)
{
System.out.println((Integer)x-1);
}
}
}
Output

221
332
