So I'm having an issue reading a text file into my program. Here is the code:
try {
InputStream fis = new FileInputStream(targetsFile);
BufferedReader br = new BufferedReader(new InputStreamReader(fis));
//while(br.readLine()!=null){
for (int i = 0; i < 100; i++) {
String[] words = br.readLine().split(" ");
int targetX = Integer.parseInt(words[0]);
int targetY = Integer.parseInt(words[1]);
int targetW = Integer.parseInt(words[2]);
int targetH = Integer.parseInt(words[3]);
int targetHits = Integer.parseInt(words[4]);
Target a = new Target(targetX, targetY, targetW, targetH, targetHits);
targets.add(a);
}
br.close();
} catch (Exception e) {
System.err.println("Error: Target File Cannot Be Read");
}
The file I am reading from is 100 lines of arguments. If I use a for loop it works perfectly. If I use the while statement (the one commented out above the for loop) it stops at 50. There is a possibility that a user can run the program with a file that has any number of lines, so my current for loop implementation won't work.
Why does the line while(br.readLine()!=null)
stop at 50? I checked the text file and there is nothing that would hang it up.
I don't get any errors from the try-catch when I use the while loop so I am stumped. Anyone have any ideas?
You're calling br.readLine()
a second time inside the loop.
Therefore, you end up reading two lines each time you go around.
