我正在尝试开发巡航控制系统的Java应用程序。但是我没有这样的文件异常问题。因为我在java编码方面有点新。我不知道为什么会出现这个问题。我的代码是 -Java显示错误NoSuchFileException
public static void main(String[] commandLineArgs) throws IOException {
Path input_path = Paths.get(commandLineArgs[0]);
List<InputState> input_states = StateInput.input_states_from_file(input_path);
Timer timer = new Timer(new CruiseControlSystem());
List<OutputState> output_states = timer.pulse_from_input(input_states);
for (OutputState s : output_states){
System.out.println(s.format());
}
}
而且我发现的错误是 -
Exception in thread "main" java.nio.file.NoSuchFileException: commandLineArgs[0]
at sun.nio.fs.WindowsException.translateToIOException(Unknown Source)

at StateInput.input_states_from_file(StateInput.java:31)
at CommandLine.main(CommandLine.java:23)
我的主要方法是 -
public static void main(String[] commandLineArgs) throws IOException {
Path input_path = Paths.get(commandLineArgs[0]);
List<InputState> input_states = StateInput.input_states_from_file(input_path);
Timer timer = new Timer(new CruiseControlSystem());
List<OutputState> output_states = timer.pulse_from_input(input_states);
for (OutputState s : output_states){
System.out.println(s.format());
}
}
@kushagra_mittal我hav修改了我的问题,并给出了主要方法 – ktina51
你使用eclipse或命令行来运行这个吗? –
