Question

我正在创建一个简单的Cron Scheduler。我没有IDE工作，所以文件没有编译

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
public class CronJob implements Job{

public void execute(JobExecutionContext arg0) throws JobExecutionException {
    // TODO Auto-generated method stub
    System.out.println("Regular");
    SendRegular sR = new SendRegular();
    sR.Reglar();
    System.out.println("Reappear");
    SendReappear SR = new SendReappear();
    SR.Reapp();
   }
}

这是我正在编译的代码

java CronSched

这是我运行代码的方式，我收到以下错误

哪里错了？

Answer 1

 javac -cp ".:/home/aditya/CronSched/CronSched/lib/quartz-2.2.3/lib/quartz-2.2.3.jar" CronJob.java

不要编译两个石英文件，IDE会接受它但是化学编译不接受

Answer 2

以下是在命令行上使用javac -cp的一些示例：
