是否可以使用ProcessBuilder运行外部.class文件？

Question

I am trying to create a new Process that runs another class file I wrote, with specific VM arguments. I am trying to run a class file called "Main2.class" (which has a main method) from my Bin directory, but I'm getting

java.io.IOException: Cannot run program "/Users/Dean_Leitersdorf/Documents/workspace/project/bin/packageA/Main2.class": error=13, Permission denied

The code I have:

File f = new File("/Users/Dean_Leitersdorf/Documents/workspace/project/bin/packageA");
    ProcessBuilder builder = new ProcessBuilder(new String[]{f.getAbsolutePath() + "/Main2.class","-Xdebug", "-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4000"});

Process process = builder.start();

Is this even possible? If so, I would greatly appreciate any help to make it work!

Thank you,

Dean

是的，您可以运行它，但是您必须使用java.exe调用它，就像在命令行中一样。
