Take a look at the following classes...

public class A  {
	public String declaration1;
	public String declaration2 = "This is ClassA:declaration2";
	public int int1;
	public int int2;

	public A()  {
		declaration1 = "This is ClassA:declaration1";
		declaration2 = "This is ClassA:declaration2, renamed";
	}

	public A(int int1, int int2)  {
		this.int1 = int1;
		this.int2 = int2;
	}

	public int getInt1()  {
		return int1;
	}

	public int getInt2()  {
		return int2;
	}
}

public class B extends A  {
	public String declaration1;
	public String declaration2 = "This is ClassB:declaration2";
	public int int1;
	public int int2;

	public B()  {
		declaration1 = "This is ClassB:declaration1";
	}

	public B(int int1, int int2)  {
		super(int1,int2);
		this.int1 = int1 + 1;
		this.int2 = int2 + 1;
	}

	public int getInt1()  {
		return int1;
	}
}

public class Main  {
	public static void main(String args[])  {
		A A1 = new B(2,3);
		A A2 = new B();
		System.out.println("---Testing A1---");
		System.out.println(A1.declaration2);
		System.out.println(A1.int1);
		System.out.println(A1.getInt1());
		System.out.println(A1.int2);
		System.out.println(A1.getInt2());
		System.out.println();
		
		System.out.println(A2.declaration1);
		System.out.println(((B)A2).declaration2);
	}
}

Your job is to figure out what main() prints out.  This will test your knowledge of what you learned in section for this week.
