I am making a snake game for my class project in school. Everything was fine until I looked at my code. It produced no errors when I "build" it but returns NumberFormatException.
PS I am only a 1st year college student. Please be gentle
private void checkScore() throws IOException{
try{
bw = new BufferedWriter(new FileWriter("scores.txt"));
if(score > Integer.parseInt(highest)){
highest = Integer.toString(score);
} else {
}
}catch(IOException e){
}
bw.write(score);
bw.close();
}
The result I want from this is that when a player ends the game, the score would get recorded. If its a high score then it would be recorded in a scores.txt file. But my BufferedWriter refuses to write a file which results to the error mentioned.
The problem is that highest
has not a valid integer value when you do Integer.parseInt(highest)
. Use debug options to see which value contains and fix that problem.
