Thread: What is wrong with my code?

I am trying to print this to a file:

        try {
 
        PrintWriter outfile = new PrintWriter(new FileWriter("CD.txt", true));
        outfile.println(title+","+singer+","+price+","+Category+","+discount + ",");
 
     for(int t=0;t<NumOfTracks;t++){
       Tracks[t]=(Newtrack);
       duration[t]=(Newtime);
       outfile.println(Tracks[t] + "," + duration[t]+ ",");
            t++;
        }
        outfile.close();
        }

Whenever i print it to the file, i get
title,singer,price,category,discount,track1,time1
title,singer,price,category,discount,track2,time2

I want it to be like this
title,singer,price,category,discount,track1,time1, track2,time2.

Why is it printing the same thing again and writting the track2 and time2 to it?

Thank you
