错误：java.io.FileNotFoundException:args[0]

这是HitHub的代码，用于我的学习目的。我尝试在eclipse中运行它，但出现如下错误：

Exception in thread "main" org.matsim.core.utils.io.UncheckedIOException: java.io.FileNotFoundException: args[0]

public class RunCarsharing {

    public static void main(String[] args) {
        Logger.getLogger( "org.matsim.core.controler.Injector" ).setLevel(Level.OFF);

        final Config config = ConfigUtils.loadConfig(args[0]);
        CarsharingUtils.addConfigModules(config);

        final Scenario sc = ScenarioUtils.loadScenario(config);

        final Controler controler = new Controler( sc );

        installCarSharing(controler);

        controler.run();
    }

    public static void installCarSharing(final Controler controler) {
        Scenario sc = controler.getScenario() ;

        controler.addOverridingModule( new AbstractModule() {
            @Override
            public void install() {
                this.addPlanStrategyBinding("RandomTripToCarsharingStrategy").to( RandomTripToCarsharingStrategy.class ) ;
                this.addPlanStrategyBinding("CarsharingSubtourModeChoiceStrategy").to( CarsharingSubtourModeChoiceStrategy.class ) ;
            }
        });

        controler.addOverridingModule(new AbstractModule() {
            @Override
            public void install() {
                bindMobsim().toProvider( CarsharingQsimFactory.class );
            }
        });

        controler.setTripRouterFactory(CarsharingUtils.createTripRouterFactory(sc));

        //setting up the scoring function factory, inside different scoring functions are set-up
        controler.setScoringFunctionFactory(new CarsharingScoringFunctionFactory( sc.getConfig(), sc.getNetwork()));

        final CarsharingConfigGroup csConfig = (CarsharingConfigGroup) controler.getConfig().getModule(CarsharingConfigGroup.GROUP_NAME);
        controler.addControlerListener(new CarsharingListener(controler,
            csConfig.getStatsWriterFrequency() ) ) ;
    }
}

主要程序如下：

如果代码和stacktrace是准确的，那么获得异常消息的唯一方法是，如果有人试图打开一个文件名为“

”args[0]”的文件。

1）我认为这不是真正的错误消息。我想你已经“按摩”了。2） 程序应该至少使用一个命令行参数运行，该参数是配置文件的路径名。我猜你给它的命令行参数不正确

FileNotFoundException

表示Java找不到您（程序）要求它打开的文件。它与导入文件有关吗？我在参考库中有一些导入文件，即.class文件.Java导入？否。如果在加载类时缺少“.class”文件，则会出现不同的异常。
