Question

I have a program that reads from a txt file line by line splits up the string and puts it in to an arraylist

while ((inputLine2 = infile2.readLine() )!= null)
{

    //string to split up
    String[] programData = inputLine2.split(":");
    List<CoursesInProgram> programContents = new ArrayList(programContents);
    //constructor

      programContents.add(new CoursesInProgram(programData[2],programData[3],
            programData[4],programData[5],programData[6],programData[7],
            programData[8],programData[9]));
    //other constructor
    programlist.add
    (new Program(programData[0],programData[1], programContents));        

} 

And I get the error The local variable programContents may not have been initialized. Reading here I learned that happens when eclipse thinks that it possible i’ll never enter the loop.

so I changed it to a do while loop and still had the same problem.
then i tried to initialize the array outside the loop and i got a duplicate variable error.

what do you think is the solution?

Answer 1

List<CoursesInProgram> programContents = new ArrayList(programContents): the variable programContents appears twice here; what do you expect to happen?
