I am working on a project that obtains data from a .txt file and processes it into 3 different variable Show, Series, Episodes.
I'm running into null object reference error and having trouble fixing it not too sure where i am messing up with this one. please any help you can give me would be greatly appreciated as I don't have much time left to finish this project before it is due for assessment.
Calling function.
public void GetSetShowData(int Count){
String[] ShowsStrings = FileRead.ReadUpdates("TvShows.txt",Count);
Shows[] ShowData = new Shows[LineCount];
for(int i = 0; i <= Count;i++) {
String Temp = ShowsStrings[i];
String[] Temp2;
Temp2 = TextUtils.split(Temp, ",");
Log.d("Line count: ", ""+LineCount);
Log.d("Temp2 length", Integer.toString(Temp2.length));
Log.d("Temp2[0] contains: ", Temp2[0].trim());
Log.d("Temp2[1] contains: ",Temp2[1]);
String name = Temp2[0];
Log.d("name: " , name);
ShowData[0].setName(name);
Integer series = Integer.parseInt(Temp2[1].trim());
Log.d("series:", " " + series);
ShowData[i].setSeries(series);
for(int i2 = 0;i2 >= (Temp2.length- 2);i2++ ){
ShowData[i2].setEpisodes(i,Integer.parseInt(Temp2[i2 + 2]));
}
for(int log = 0; log > Temp2.length; log++){
Log.d("Show Data: " + i , "Series: " + ShowData[i].getSeries() + " Episode: " + ShowData[i].getEpisodes(log));
}
}
}
Class Shows (Multi datatype array)
public class Shows {
public String Show = "";
public int SeriesAmount = 0;
public ArrayList<Integer> Episodes = new ArrayList<>();
public Shows(){
}
public void setName(String Name){
Show = Name;
}
public String getName(){
return Show;
}
public void setSeries(int Series){
SeriesAmount = Series;
}
public int getSeries(){
return SeriesAmount;
}
public void setEpisodes(int Position, int Episode){
Episodes.add(Position,Episode);
}
public int getEpisodes(int Position){
return Episodes.get(Position);
}
}
This is the error message i am receiving.
