Q1.This program is related to the generation of Fibonacci numbers.

For example: zero,1, 1,2, 3,5, 8, 13,… may be a sequence wherever thirteen is that the eighth Fibonacci number.

A partial code is given and you have got to finish the code as per the instruction given below.

if (n==1)
return 0;
else if(n==2)
return 1;
return fib(n – 1) + fib(n – 2);

Q2. Define a class Point with two fields x and y each of type double. Also, define a method distance(Point p1, Point p2) to calculate the distance between points p1 and p2 and return the value in double.

Complete the code segment given below. Use Math.sqrt( ) to calculate the square root.

class Point{
double x;
double y;

public static void distance(Point p1,Point p2){
double d;
d=Math.sqrt((p2.x-p1.x)*(p2.x-p1.x) + (p2.y-p1.y)*(p2.y-p1.y));

Q3. A class Shape is defined with two overloading constructors in it. Another class Test1 is partially defined which inherits the class Shape. The class Test1 should include two overloading constructors as appropriate for some object instantiation shown in main() method. You should define the constructors using the super class constructors. Also, override the method calculate( ) in Test1 to calculate the volume of a Shape.

double height;
Test1(double length,double h) {


Test1(double length,double breadth,double h) {


double calculate() {
return length*breadth*height;

Q4. This program to exercise the call of static and non-static methods. A partial code is given defining two methods, namely sum( ) and multiply ( ). You have to call these methods to find the sum and product of two numbers. Complete the code segment as instructed.  


QuestionScope st = new QuestionScope();
int result1=st.sum(n1,n2);
int result2=QuestionScope.multiply(n1,n2);


Q5. Complete the code segment to swap two numbers using call by object reference.

static void swap(Question obj) {

int temp;
