Question

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. You also will use a file named DebugEmployeeIDException.java with the DebugTwelve4.java file.

Code I was given-

public class DebugEmployeeIDException extends Exception

{

public DebugEmployeeIDException()

{

super(s);

}

// An employee ID can't be more than 999

// Keep executing until user enters four valid employee IDs

// This program throws a FixDebugEmployeeIDException

import java.util.*;

public class DebugTwelve4

{

public static void main(String[] args)

{

Scanner input = new Scanner(System.in);

String inStr, outString = "";

final int MAX = 999;

int[] emps = new int[4];

for(x = 0; x < emps.length; ++x)

{

System.out.println("Enter employee ID number");

inStr = input.next();

throw

{

emps[x] = Integer.parseInt(inStr);

if(emps[x] > MAX)

{

throw(new FixDebugEmployeeIDException("Number too high " + emp[x]));

}

catch(NumberFormatException error)

{

--x;

System.out.println(inStr + "\nNonnumeric ID");

}

catc(FixDebugEmployeeIDException error)

{

--x;

System.out.println(");

}

for(int x = 0; x < emps.length; ++x)

{

outString = outString + empss[x] + " ";

}

System.out.println("Four valid IDS are: " + outString);

}
