How can I call a main function of a Java class?

E.g: I got a Java class with the main function implemented like this:

public class Job{
    public static void main(String[] args) throws Exception{
        Job jobA = new Job();
        String jobName = System.getProperty("JobName");
        job.DoJobA("jobName");
    }

    public void DoJobA(String jobName){
        String configPath = System.getProperty("ConFig");
        File file = new File(configPath+ "/" + jobName);
        DoJobB(file);
    }
}

And I another class and want to call the main function of class Job but couldn't find a way to do that! Is there any advise for me?

If you make the main method use var args then you dont need to pass in any variable

public static void main(String... args) throws Exception{
    ...
}

then you can just call it as

Job.main();

if you need arguments then you can pass them if.

You should be able to call it like you call any other static method

Job.main(yourArgs);
