inheriting variables

[marilyn murphy]

<font size=+0>class Base{
    int i = 100;
  
    Base(){
      System.out.println(i);
    }
}
  
public class Pri extends Base{
    static int i = 200;
    int i = 100 ; // line 1
  
    public static void main(String argv[]){
Pri p = new Pri();
System.out.println(i);
    }
}

Since this code will not compile if the line marked "line 1" is not commented out due to "i is already defined in Pri", why don't we get the same compile error due to the i Pri inherited from Base?

Hello Marilyn,
There are no errors because the 'i' in the class 'Pri' hides the 'i' in the class 'Base'. If you don't want this you can change the name of the variable to something else. Also I just modified your code. Have a look.

<font size=+0>
class Base{
   int i = 100;
 }
 public class Pri extends Base{
    static int i = 200;
    public Pri(){
      System.out.println(" This is the value of i from Base class - "+ super.i);
      System.out.println(" This is the value of i from Pri class - " + i);
      System.out.println();
    }
   
    public static void main(String args[]){
Pri p = new Pri();
        System.out.println(" Value of i in Pri class is = "+ i);
        System.out.println(" Value of i in Base class is = "+ new Base().i);
    }
 }

So i in Pri hides i in Bases even though one 'i' is static and the other is not?

[R K Singh]

I think yes.. as both have same identifier. yes but static var can be access by class name also and can be used in static methods.
CMIW
even static methods are not overridden but they are hide.

Hello Marilyn,
That is true that i in Pri will hide i in Base even if one is static and other is not. But you need to comment Line 1, as you already had one variable named i in the current scope. You can't declare two variable with the same name in the same scope.
