Java Week 3: Q1

This program is related to the generation of Fibonacci numbers.

For example: 0, 1, 1, 2, 3, 5, 8, 13,… is a Fibonacci sequence where 13 is the 8thFibonacci number. A partial code is given and you have to complete the code as per the instruction given as comments.

PROGRAM:

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

Java Week 3: 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.

PROGRAM:

class Point{
  
 double x,y;
  
   void distance(Point p1,Point p2){
   double diff,xx,yy;
    xx=p2.x-p1.x;
    yy=p2.y-p1.y;
    
    diff=Math.sqrt(xx*xx+yy*yy);      //   sqrt((x2-x2)2  +(y2-y1)2)  simply use distance formula
    System.out.print(diff);
    
  }
  
  
}
