Access modifiers and packages

[Satyajeet Kadam]

I am new to java. I am learnning access modifers and acess control. Thisis my error


package cert;
public class Base
{
int i;
public int j;
protected int k;
private int l;
}
package stuff;
import cert.*;
public class Child extends Base
{
Base obj=new Base();
obj.j=11;
public static void main(String[] args)
{ System.out.println("Hello World!");
}
}
Child.java:7: <identifier> expected
obj.j=11;
^ Child.java:7: package obj does not exist
obj.j=11;

Since, j is public varable in base class. So it is legal to access
in child class even though it is another package

you cannot reference obj outside a method.

Change your code to the following:

public class Child extends Base
{
Base obj=new Base();
public Child() {
    obj.j=11;
}
public static void main(String[] args) { 
    System.out.println("Hello World!");
}
}
Child

obj.j=11;

Keep the above statement in any method in the constructor or method, it works.

As Jeremy said you cannot reference non static variables outside a method or constructor.
