How to execute “javac and java commands” from java program?

问题

Is there any way to execute "javac and java commands" from java program?
If so,please help me out....

回答1:

Like Runtime.getRuntime().exec("javac ..."); ?

回答2:

You can use Runtime.getRuntime.exec() to do this. But there're some common traps that you take care of. This article on "When Runtime.exec() won't" work correctly highlights some of them.

回答3:

You can use the ProcessBuilder class

 ProcessBuilder pb =
   new ProcessBuilder("javac", "arg1, "arg2");

回答4:

I would suggest using http://docs.oracle.com/javase/6/docs/technotes/tools/ instead of attempting to execute javac. It gives you much more control and returns usable information

回答5:

I know Open the explorer：Runtime.getRuntime().exec("explorer"); so I guess Runtime.getRuntime().exec("java"); and Runtime.getRuntime().exec("javac"); You can give it a try.

回答6:

I suggest you use Apache Commons Exec, It provides a simple API. Cheers!

回答7:

the best way is to run by invoking os shell and then by passing javac and java tools.

take the result by using inputstream and print it
