Thread: problem reading text file to hash map

So on my assignment I created a class to read a TXT file into a hashmap the txt contents is like this

1<>John Kane
2<>Jane Lyman
3<>Peter Hansen
4<>Cathy Harris
5<>Rose Makki
6<>Michael O'Connor

what i have so far

public class Reader
{
    static Map<Integer, String> instructors, courses;
    private static final String SEPARATOR = "<>";
 
 
    public static Map<String, String> getInstructors()
    {
        try
        {
          BufferedReader in = new BufferedReader( new FileReader("instructor.txt"));
 
             instructors = new LinkedHashMap<String, String>();
 
             String line1;
 
            while(((line1 = in.readLine()) != null))
            {
                line1 = in.readLine();
                String[] val1 = line1.split(SEPARATOR);
                String ID = val1[0];
                String name = val1[1];
 
                instructors.put(ID, name);
            }
            in.close();
        }
        catch(IOException ioe)
        {
            ioe.printStackTrace();
        }
 
        return instructors;
        }
    public static Map<String, String> getCourses()
    {
        try
        {
          BufferedReader in = new BufferedReader( new FileReader("course.txt"));
 
             courses = new LinkedHashMap<String, String>();
 
             String line2;
 
            while(((line2 = in.readLine()) != null))
            {
                line2 = in.readLine();
                String[] val2 = line2.split(SEPARATOR);
                String ID = val2[0];
                String name = val2[1];
 
                courses.put(ID, name);
            }
 
         in.close();
        }
        catch(IOException ioe)
        {
            ioe.printStackTrace();
        }
 
       return courses;
        }
}

I passed the instructor and course hashmap to my mainapp, but two problems occur when i try to display them onto a textarea with only the name

my instructor textarea appeared only 2, 6, and 4,(the actual name), and my courses throws an error refering to line 52 String[] val2 = line2.split(SEPARATOR); throwing an Exception in thread "main" java.lang.NullPointerException

can anyone help me out on this?
