Consider the following classes: public class Top{ int x; public Top (int x){ this.x = x + 1; } } public class Middle extends Top{ public Middle (int y) { super(2*y); this.x = x - 1; } } public class Bottom extends Middle{ public Bottom(int z) { super (z+3); } } In a program, if we have Тоp t System.out.println( t.x % 10 ); new Bottom(3); what will be displayed to the screen? Note: x % 10 will be the right-most digit of x when x is a positive integer. For example, 13 % 10 is 3, and 18628 % 10 is 8.

Assume you have the following definition of class A: public class A { private int x; private String s; public A( int a, String b) { x = a; s = b; } } And the following fragment of code: String s1 = "Hello"; A а1 = new A(10, s1); А а2 = new A(10, s1); A a3 = new A(20, s1); Which of the comparisons using equals is true? a2.equals(a3) a1.equals(a3) a1.equals(a2) None of the above.
