In each of the following questions, first use NetBeans IDE to run the code (if there is an error fix it) then take a screenshot of the output and paste it under (A). In (B), justify the output you obtained in (A). - 9. Given the following: public class WorkingSheet { public static void main(String[] args) { B myB = new B(); A myA = new B(); System.out.print(myB instanceof A); System.out.print(myB instanceof C); System.out.print(myA...
The following code is a Java code for insertion sort. I would like this code to be modified by not allowing more than 10 numbers of integer elements (if the user enters 11 or a higher number, an error should appear) and also finding the range of the elements after sorting. /* * Java Program to Implement Insertion Sort */ import java.util.Scanner; /* Class InsertionSort */ public class InsertionSortTwo { /* Insertion Sort function */ public static void sort( int...

Creating a calculator for my CS1 class and my code was able to run but it crashes near the end. As far as I know, the error means that it's retrieving "null" from the variable but I haven't seen that kind of error from this kind of situation. I would appreciate any help. I'm just starting up in Java so I apologize if this is a silly question. Thank you! ``` ----jGRASP exec: java CS1Calculator ------------ Welcome to the CS1...
