This is a debugging question -

The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly.

This is the code I am struggling with -

// Prompt user for value to start

// Value must be between 1 and 20 inclusive

// At command line, count down to blastoff

// With a brief pause between each displayed value

import java.util.*;

public class DebugSix3

{

public static void main(String[] args)

{

Scanner input = new Scanner(System.in);

String userNumString;

int userNum, val;

final int MIN = 1;

final int MAX = 20;

System.out.println("Enter a number between " + MIN + " and " + MAX + " inclusive");

userNumString = input.next();

userNum = Interger.parseInt(userNumString);

while(userNum < MIN || userNum = MAX)

{

System.out.println("Number out of range" +

"\nEnter a number between " + MIN + " and " + MAX + " inclusive");

userNumString = input.next();

userNum = Integer.parse(userNumString);

}

for(val = userNum; val < 0; --val)

{

System.out.print(val + " ");

for(int x = 0; x < 100000; ++x)

for(int y = 0; y < 10000; ++y);

// Adjust these numbers for faster or slower performance

}

System.out.println("Blastoff!");

}
