I am stuck at this problem for a week.
I tried to declare an array outside the main method
public class XXX {
public static Array [] newarray = new newarray [20];{
newarray [0] = new Array ("1","1");
//declaring array up to 20
}
public static void main(String args[]){
System.out.println(newarray[0]);} // i cannot
retrieve the array in main method.
The output shows the newarray[0] = null. What did i do wrong here?
P.S.: assuming Array.java has appropriate constructor, setter and
getter.

I cannot help unless there is an actual program. This text is not a program.
