Write an input verification loop that ensures that the user enters a positive integer as input. You may assume that a Scanner object called scan has already been created. use Java.

The following code is in Java: // Assume inputFile references a Scanner object. try {    input = inputFile.nextInt(); } finally {    inputFile.close(); } catch (InputMismatchException e) {    System.out.println(e.getMessage()); }   1)What is the issue with this code?2) How can it be fixed?

Complete the following program to implement the user interface of the preceding exercise. For simplicity, only the units cm, m, and in are supported. Hint: The value of factor1 or factor2 should be the conversion factor from the selected unit to cm. Ex: If the selected unit is in, factor1 is 2.54 because 1 in = 2.54 cm."in java"

Hi I am having some difficulties with this problem, I am not sure why my code is giving an incorrect output.   Here is the provided code: import java.util.Scanner;  public class DrawHalfArrow {   public static void main(String[] args) {      Scanner scnr = new Scanner(System.in);      int arrowBaseHeight;      int arrowBaseWidth;      int arrowHeadWidth;            System.out.println("Enter arrow base height:");      arrowBaseHeight = scnr.nextInt();            System.out.println("Enter arrow base width:");      arrowBaseWidth = scnr.nextInt();            System.out.println("Enter arrow head width:");      arrowHeadWidth = scnr.nextInt();      System.out.println("");            // Draw arrow base (height = 3, width = 2)      System.out.println("**");      System.out.println("**");      System.out.println("**");            // Draw arrow head (width = 4)      System.out.println("****");      System.out.println("***");      System.out.println("**");      System.out.println("*");   }}…
