Hi Friends,

The following is the code:
package shreejava;
public class A1{
protected int x;
A1(int q){ x=q;}
the above sourcefile is saved as C:\shreejava\
package aaj;
import shreejava.*;
public class C extends A1 {

C(int j){super(j);}
public static void main(String arf[]){
C y = new C(10);
the above sourcefile is saved as C:\aaj\
when i try to compile it using C:\aaj>javac -sourcepath C:\ command,I am getting a compile error "No Constructor matching A1(int) found in class shreejava.A1"
what is wrong in this code?
thanx in advance.

Try this in A1:
package shreejava;
public class A1{
protected int x;
A1(int q){ x=q;}
That should take care of it. Someone correct me if I am wrong, but when you extend a superclass, you need AT LEAST the constructor with no parameters for that superclass.

Because the constructor in A1 has no access level indicated it gets package level access. This means that only classes in the same package can access that constructor.
