のためのレベルでテキストファイルを読み込む必要があり、私は後で区切るそれらをdesplayことができるように許可さ? 彼らは出かける必要があります。 to;しかし、行をする必要が無傷で
public class LevelReader {
private List<String> levels;
private final InputStream inputStream;
public LevelReader() {
this.inputStream = this.getClass().getResourceAsStream("Levels.txt");
this.readLevels();
}
private void readLevels() {
try (BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream))) {
List<String> lines = new ArrayList<>();
String line = reader.readLine();
while (line != null) {
line = reader.readLine();
levels = new ArrayList<>();
if (line.startsWith(";")) {
levels.addAll(lines);
lines.clear();
System.out.println(levels);
}
lines.add(line);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
At this moment it kinda works but i still get alotof errors

これは私の宿題のようです。ここで質問するのではなく、Javaチュートリアルを検索してみてください。 – abbath
