Analyze the following code: public class Test { public static void main(String[] args) { try { String s= "5.6"; Integer.parseInt(s); // Cause a NumberFormatException } } catch (Exception ex) { System.out.println("NumberFormatException"); int i = 0; int y = 2/i; } catch (RuntimeException ex) { } } System.out.println("RuntimeException"); The program displays Number FormatException. The program displays RuntimeException. The program displays NumberFormatException followed by RuntimeException. The program has a compile error.

TASK 5. Methods Overloading. Review Methods, Implement the following code, test it with different input, make sure it runs without errors.
Use mathematical induction to show that when n ≥ 2 is an exact power of 2, the solution of the recurrence 2 = {²T (m/2) T(n) = if n = 2, 2T (n/2) +n ifn > 2 is T(n) = n lgn.
Fix all errors to make the code compile and complete. //MainValidatorA3 public class MainA3 { public static void main(String[] args) { System.out.println("Welcome to the Validation Tester application"); // Int Test System.out.println("Int Test"); ValidatorNumeric intValidator = new ValidatorNumeric("Enter an integer between -100 and 100: ", -100, 100); int num = intValidator.getIntWithinRange(); System.out.println("You entered: " + num + "\n"); // Double Test System.out.println("Double Test"); ValidatorNumeric doubleValidator = new ValidatorNumeric("Enter a double value: "); double dbl = doubleValidator.getDoubleWithinRange(); System.out.println("You entered: " + dbl + "\n"); // Required String Test System.out.println("Required String Test:"); ValidatorString stringValidator = new ValidatorString("Enter a required string: "); String requiredString =…
Complete the convert() method that casts the parameter from a double to an integer and returns the result.Note that the main() method prints out the returned value of the convert() method. Ex: If the double value is 19.9, then the output is: 19 Ex: If the double value is 3.1, then the output is: 3 code: public class LabProgram { public static int convert(double d){ /* Type your code here */ } public static void main(String[] args) { System.out.println(convert(19.9)); System.out.println(convert(3.1)); }}
public class main { public static void main(String [] args) { Dog dog1=new Dog(“Spark”,2),dog2=new Dog(“Sammy”,3); swap(dog1, dog2); System.out.println(“dog1 is ”+ dog1); System.out.println(“dog2 is ”+ dog2); } public static void swap(Dog a, Dog b) { String nameA = a.getName(); String nameB = b.getName(); a.setName(nameB); b.setName(nameA); } What is the output of the main()?
If feasible, specific descriptions of multiplexors and demultiplexors should be included. How crucial is it to understand the functions of data bits and the selection bit?
Java Questions - (Has 2 Parts). Based on each code, which answer out of the choices "A, B, C, D, E" is correct. Each question has one correct answer. Thank you. Part 1 - Given the following code, the output is __. class Sample{ public static void main (String[] args){ try{ System.out.println(5/0);}catch(ArithmeticException e){ System.out.print("Divide by zero????");}finally{ System.out.println("5/0"); } }} A. Divide by zero????B. 5/0C. Divide by zero????5/0D. 5/0Divide by zero????E. "5/0" Part 2 - Given the following code, the output is __. try{ Integer number = new Integer("1"); System.out.println("An Integer instance.");}catch (Exception e){ System.out.println("An Exception.");} A. An Integer instance.B. An Exception.C. 1D. Error: ExceptionE. None of the options
TASK 3. Console Input and Output. Review Scanner class and its methods, Implement the following code, make sure it runs without errors. 1 package 1lessons; 3 import java.util.Scanner; 4 5 public class ReportSum3 { public static void main(String args[]) { Scanner sc = new Scanner(System. in); 60 7 8 // Prompt the user to enter the first integer System.out.println("Enter the value for 'a' and press Enter: "); int a = sc.nextInt(); // Prompt the user to enter the second integer System.out.println("Enter the value for 'b' and press Enter: "); int b = sc.nextInt(); 10 11 12 13 14 15 16 17 18 19 20 21 22 } //Close the Scanner. It's a good practice to release the resource that was acquired sc.close(); // Display the result System.out.printf( "Provided Integers: %4d and %4d, the total is %5d\n", a, b, (a + b)); } To simplify the task, we came out with the idea to use Methods. Implement a method to add two integers.
