I've implemented the file reader code from this scenario into my own project. The section of code used is as follows:
Upon trying to call this method in a different class, I get no errors. In order to display the text, I use the addObject method like so:
(TextObj just has a single line of code that sets its image to the given text.) I am given the error "java.util.List<java.lang.String> cannot be converted to java.lang.String, which I presume means that the parameter I gave when calling the loadFile method was not in fact a string. I tried using the toString method and creating a string variable, however both return the same error. I should also probably mention that I do not understand most of what is in the loadFile method. Is there any sort of way I can fix this?
public static java.util.List<String> loadFile(String filename) {
ArrayList<String> fileText = new ArrayList<String>();
BufferedReader file = null;
try {
file = new BufferedReader(new FileReader(filename));
String input;
while ((input = file.readLine()) != null) {
fileText.add(input);
}
}
catch (FileNotFoundException fnfe) {
//fnfe.printStackTrace();
return null;
}
catch (IOException ioe) {
//ioe.printStackTrace();
return null;
}
finally {
try {
file.close();
}
catch (IOException ioe) {
ioe.printStackTrace();
}
catch (NullPointerException npe) {
//npe.printStackTrace();
}
}
return fileText;
}addObject(new TextObj(Reader.loadFile("data/nationdata.txt")),300,200);
