- 2) Two integers are said to be relatively prime if their greatest common divisor (GCD) is one. For example 12 and 13 are relatively prime, but 12 and 14 are not. a. Write a method called relativelyPrime that accepts two integer parameters A and B. The method should output if A, and B are relatively prime or nat. Use the following method header: public static void relativelyPrime(int A, int B) b. Write a test program (main) to test the method by asking the user to input two positive integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are relatively prime or not. Sample Run 1: Enter Two positive integers X and Y: 12 13 12 and 13 are relatively prime Sample Run 2: Enter Two positive integers X and Y: 12 14 12 and 14 are not relatively primeMethod Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.Please find the errors in the following program & explain why are they considered errors: 3 4 class Point2{ 5 6 8 9- 10 11 12- 13 14 15 - 16 17 18 19 20 21 } public : } float x,y; Point2(float iX, float iY):x(ix),y(iY){} static Point2 operator-(float shift) const { return Point2(x-shift, y-shift); } static void operator+=(float shift) const { x += shift; y+=shift; } int main() { Point2 p1(3,2); Point2 p2 1-p1; p2+ = 5; =
- Problem: Construct a program that simulates the major Bank Transactions: Deposit, Withdraw and Inquire. Your program should use methods for the 3 transactions and another method for the login transaction. Below is the initial structure of the your code: public class BankTransaction { static void DisplayMenu() { /*this method displays the menu of the transactions*/ } static void withdraw(float amount) { /*this method should deduct the amount withdrawn from the current balance*/ } static void deposit(float amount) { /*this method should add the amount deposited to the current balance*/ } static float inquire() { /*this method should return the current balance*/ } static boolean CorrectPinNUmber() { /*this method should ask user to input the pin number. returns TRUE if the pin number is valid*/ It } public static void main(String a[]) { } } Design your main program to test these methods. You can design your own user interface.42) Look at the following method: public static int test2 (int x, int y) if (x < y) { return -5; } else { return (test2 (x - y, y + 5) + 6) ; } } What is returned for test2 (10, 20)? A) -5 B) 1 C) 6 D) 10 43) This term is used for methods that directly call themselves. A) Simple recursion C) Absolute recursion B) Direct recursion D) Native recursion 44) If the base case in a recursive method is never reached: A) The result will always be off by one. C) The method will call itself indefinitely. B) The method will call itself only once. D) The method will never call itself. 45) A(n) is an object that is generated in memory as the result of an error or an unexpected event. A) exception C) default exception handler B) exception handler D) error message 46) All of the exceptions that you will handle are instances of classes that extend this class. A) Exception C) IOException B) RunTimeException D) Error 47) All exceptions are instances of dasses that extend this class. A) Throwable C)…Analyze the following code: public class Test ( //main function double radius; final double PI= 3.15169; double area = radius radius " Pl; System.out.println("Area is"+ area); Select one: a. The program has a compile error because a constant Pl is defined inside a method. O b. The program compiles and runs fine. O c. The program has compile errors because the variable radius is not initialized. O d. The program has no compile errors but will get a runtime error because radius is not initialized.

- Problem 1: Complete the isExactReverse() method in Reverse.java as follows: The method takes two Strings x and y as parameters and returns a boolean. The method determines if the String x is the exact reverse of the String y. If x is the exact reverse of y, the method returns true, otherwise, the method returns false. Other than uncommenting the code, do not modify the main method in Reverse.java. Sample runs provided below. Argument String x "ba" "desserts" "apple" "regal" "war" "pal" Argument String y "a" "stressed" "apple" "lager" "raw" "slap" Return Value false true false true true falsec) Write a public static method getFirstD() with the following: o The method accepts 2 arguments: the first argument is an array of int, and the second is a value of int. The method returns a value of int type. o The method finds and returns the last element in the array which is divisible by the second argument, e.g. 8 is divisible by 4, but 9 is not divisible by 4. I The method returns your student ID number, if no divisible number is found in the array. Use a while loop to access the array elements. *NO more than 6 statement lines are allowed in the method body. YRIGH21. Consider the following method: public static void sketch(int x1, int y1, int x2, int y2, int n) ( if (n <= 0) O else ( } drawLine(x1, y1, x2, y2); Assume that the screen looks like a Cartesian coordinate system with the origin at the center, and that drawLine connects (x1,y1) to (x2,y2). Assume also that x1, y1, x2, and y2 are never too large or too small to cause errors. Which picture best represents the sketch drawn by the method call int xm (x1 + x2 + y1 - y2) / 2; int ym (y1 + y2 + x2-x1) / 2; sketch(x1, y1, xm, ym, n - 1); sketch (xm, ym, x2, y2, n - 1); sketch(a, 0, -a, 0, 2) where a is a positive integer?
