1. Array Mystery
Consider the following method:
public static void arrayMystery(int[] a) {
for (int i = 1; i < a.length; i++) {
a[i] = i + a[i - 1] - a[i];
}
}
Indicate in the right-hand column what values would be stored in the array after the method arrayMystery executes
if the integer array in the left-hand column is passed as a parameter to it.

,2. Reference Semantics Mystery
The following program produces 4 lines of output. Write the output below, as it would appear on the console.
public class BasicPoint {
int x;
int y;
public BasicPoint() {
x = 2;
y = 2;
}
}
public class ReferenceMystery {
public static void main(String[] args) {
int a = 7;
int b = 9;
BasicPoint p1 = new BasicPoint();
BasicPoint p2 = new BasicPoint();
public static void addToXTwice(int a, BasicPoint p1) {
a = a + a;
p1.x = a;
System.out.println(a + " " + p1.x);
}
}

, 3. Inheritance Mystery
Assume that the following classes have been defined:
public class A extends B { public class C {
public void method2() { public String toString() {
System.out.print("a 2 "); return "c";
method1(); }
}
} public void method1() {
System.out.print("c 1 ");
public class B extends C { }
public String toString() {
return "b"; public void method2() {
} System.out.print("c 2 ");
}
public void method2() { }
System.out.print("b 2 ");
super.method2(); public class D extends B {
} public void method1() {
} System.out.print("d 1 ");
method2();
}
}
Given the classes above, what output is produced by the following code?
C[] elements = {new A(), new B(), new C(), new D()};
for (int i = 0; i < elements.length; i++) {
System.out.println(elements[i]);
elements[i].method1();
System.out.println();
elements[i].method2();
System.out.println();
System.out.println();
}
