(1) What is the difference between "step over" and "step in" in a debugger?

(2) How does one allocate a new object in Java? Give an example?

(3) Which statement is true regarding the following code,

Every Alpha object has two member variables, "i" and "j".
Every Beta object has two member variables, "i" and "j".

class Alpha
{
	int i;

	Alpha()
	{
	}
}

class Beta extends Alpha
{
	int j;

	class Beta()
	{
	}
}

(4) What will be the output of this code?

class Test
{
	void inc(int i)
	{
		i++;
	}

	public static void main(String[] args)
	{
		int i = 5;
		inc(i);
		system.out.println(i);
	}
}

(5) What will be the output of this code? (Hint: The answer to this question is not the same as the answer to the previous question.)

class Wrapper
{
	int i = 5;

	void inc()
	{
		i++;
	}
}

class Test
{
	public static void main(String[] args)
	{
		Wrapper w = new Wrapper();
		w.inc();
		system.out.println(w.i);
	}
}
