Answer 1

Haritha Vuppula index is not a static variable so you can't access directly with class. Call by object myApp.

And in constructor you need to write.

this.index = index;

If you will not do output will be 1
-----------------------------
class Super1 {
public int index = 1;
}

class App extends Super1{

public App(int index) {
this.index = index;
}

public static void main(String args[]) {
App myApp = new App(10);
System.out.println(myApp.index);
}
}
