query 1

class A{
	static int i;	

	int get(){
		return 1;
	}
};

class B extends A{

	int get(){
		return 2;
	}
};

class Q027 extends B{

	public static void main(String ka[]){
		Q027 obj = new Q027();
		System.out.println(obj.get());
	}
}

output:2

i think answer should be 1 as finally class Q027 would have

static int i;	

	int get(){
		return 1;
	}

	int get(){
		return 2;
	}

so 1 should be answer

------------------------------
query 2

public interface IContext
{
public double originX = 0;
}
public interface IShape extends IContext
{
public double originX = 10;
}
public class Draw implements IShape
{
public Draw()
{
double originX = this.originX;
}
}

what value would be assigned to originX ?

double originX = this.originX;  

answer:10.0

can anyone explain how ?

should not there be ambiguous compile-time error

Please KeepItDown!

For the Query 1, the get() method from class A is overridden in class B. And from class B, get() method is inherited to class Q027. And your Query 2 isn't clear!

Please give the source of this example, or it'll be deleted as a dump.

mohitkumar gupta, it would be ambiguous, if you code like below!

public interface IContext
{
public double originX = 0;
}
public interface IShape
{
public double originX = 10;
}
public class Draw implements IShape, IContext
{
public Draw()
{
double originX = this.originX;
}
}

But, in your case, the sub interface hide/shadow the inherited variable, so for the class implementing the sun interface don't have any problem with that variable!
