- *This is a handout from my class that I'm having trouble with I tried YouTube videos and I'm still lost please explain the answers as simply as you can and thank you.* A. Look over the following code fragment, give the output: try { method(); System.out.println("After the method call"); } catch (Exception ex) { System.out.println("Exception in main"); } catch (RuntimeException ex) { System.out.println("RuntimeException in main"); } static void method() throws Exception { System.out.println(1 / 0); } B. Write the code to load an array. Use simple I/O (system.out.print, etc.) to get integer values from the user and load the array (loop?). Your code has the potential to generate 2 exceptions: 1) InputMismatch (research this) and 2) IllegalValueException (assume this exists). If the 1st occurs, change the input to be 99, warn the user and continue. The 2nd exception will occur when the user enters a 0; if this occurs, notify the user that a 0 has been entered, and change the input to…Let's revisit chapter 5 example, but this time, no method can throw any exception out of the method and if an exception was detected then you will have to throw your own custom exception to let the user know what happened. public class Chapter11Demo{ public static void main(java.lang.String[] args) {method1();}private static void method1(){ method2();}private static void method2(){ method3();}private static void method3(){ method4();}private static void method4(){ method5();}private static void method5(){ method6();}private static void method6(){ java.io.File in=new java.io.File("somefile.txt"); java.io.File out=new java.io.File("somefile2.txt"); java.util.Scanner inFile=new java.util.Scanner(in); java.io.FileWriter outFile=new java.io.FileWriter(out); }}A method is implemented to compute a formula that involves dividing a quantity by a variable y. If y is 0, then an ArithmeticException will be thrown. How should you handle this situation? Here are some alternatives: 1. Ignore the problem and let your method throw an ArithmeticException. 2.Test for y==0 before doing the computation and, if found, print an error message and return 0. 3.Surround the computation with a try/catch block and print an error message in the catch block before returning 0. a. Compare these three alternatives. That means talk about how each is the same as or different than the other two. b. Is there a fourth alternative that is better than these three? If there is, give it along with a justification. If there is not, explain why not.
- Write a Java Code for the below: A prime number is a number that is evenly divisible only by itself and 1. For example, the number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 4, and 6. Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Also write main method that displays prime numbers between 1 to 500.Your class StringDoubling has a method doubleString(), which takes a String as an input parameter and returns the doubled copy of that string. Your task: Finish your main method by follow the steps outlined in your main (precisely!) Basically, your program should read in a command-line argument, print it out, and then double it 5 times (printing it out every time). For example, if your command-line value is 0, your program should output the following: 0 00 0000 00000000 0000000000000000 00000000000000000000000000000000 and if your command-line value is a, your program should output the following: a aa aaaa aaaaaaaa aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaFor this problem you will write a method that computes the number of boxes in a pyramid of boxes based on the number of boxes in the base. The boxes in each layer of the pyramid are stacked directly on top of one another (i.e. not offset between two boxes below). For example, below are shown two pyramids, one with base 5 and one with base 6. [] [][] [][][] [][][][] [][][][][] [][][][][][] Implement and test the computePyramidBoxes() method in the PyramidBoxCount class. When testing the computePyramidBoxes() method you should be sure to have at least one test method for each base case and at least one test method for each recursive case in your program.
- Solve In Python Provide Screenshots of Input and Ouput For this lab, you will modify your Lab 7 to make several improvements to the getter/settermethods. Instead of having them return True/False, modify each one to throw an exception ifinvalid data is passed.Modify these methods in the following way:• add_hours()o If the number of hours being added is less than 0, throw an exception• add_sales()o If the amount of sales being added is less than 0, throw an exception• set_employee_number()o The employee number must be an integer. If the given input is not an integer,throw an exception• set_office_number()o If the office number given is less than 100 or greater than 500, throw anexception.• set_name()o If the given name is empty, throw an exceptiono Any of the following characters should be removed from the name: ‘_’, ‘.’, ‘-‘ (Underscore, period, and dash)• set_birthdate()o If the given value for the month is less than 1 or greater than 12, throw anexceptiono If the given value for the…Consider the following test method code fragment, which tests whether a method given invalid input produces the expected exception in response. On which of the following lines should the test return false, indicating that the test has failed? There may be more than one correct answer! try { methodCall(invalidInput); // 1. line after method call } catch (IllegalArgumentException e) { // 2. correct } catch (Exception e) { // 3. incorrect } Group of answer choices 1. line after method call 2. correct 3. incorrectWrite a program that calls methods for each of the following mini problems from its main method. Us a single Scanner for the program declared in the class asprivate Static Scanner keyboard = new Scanner(System.in); Write a method that reads two strings from the user’s keyboard. Display each string, along with its width, on two separate lines. Then create a new string by joining the two strings with a space between them. Display the new string and its length on a new separate line. 2. Write a method that reads a line of text from the keyboard and then displays the line, but with the first occurrence of hate changed to love. For example, a possible sample dialogue might beEnter a line of text.I hate you.I have rephrased that line to read:I love you.You can assume that the word hate occurs in the input. If the word hate occurs more than once in the line, your program will replace only its first occurrence. 3. Write a method that asks the user to enter a favorite color, a favorite…
- Write a java program which asks the user to enter name and age and calls the following methods: a. printName(): Takes name as parameter and prints it 20 times using a while loop. b. printAge(): Takes age as parameter and prints all the numbers from 1 up to age. Please strictly follow this format. Note: any extra or missing space / line will lead to test failure. Name: Andy Age: 10 Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy Andy 1,2,3,4,5,6,7,8,9,10 class Main {public static void main(String[] args) {}}what is the java code for the class and Write one or more tests that check that the method works as specified in all cases? intro: A Fibonacci series is a popular sequence of numbers. The first two numbers of this series are 0 and 1. After this, the next Fibonacci number is obtained by adding the previous two. Thus the Fibonacci sequence is 0,1,1,2,3,5,8,13,... A Fibonacci counter is a machine that counts Fibonacci numbers. Much like a step tracker, it can be started at any count. It can be incremented or decremented by 1 (count falling below 0 is invalid). Given a number ’n’, the nth Fibonacci number can be calculated directly using Binet’s formula: ???(?)=15√((1+5√2)?−(1−5√2)?) what to do: Write a class FibonacciCounter that represents a single Fibonacci counter. This class should contain the following: A constructor that takes the initial count value and initializes the object appropriately. A method that returns a FibonacciCounter object with its count incremented by 1. A…Write a method that will take in a time in 24 hour format (1430) and return the time in 12 hour format (2:30pm). This method should have appropriate exception handling. If an incorrect time is sent as an argument (something out of bounds or 23(#4k in other words garbage), then your method should throw a TimeFormatException which you define. In no case should your method throw an unhandled exception! Show how to test the method to be sure.
