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

Question

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

Answer 1

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

Answer 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.

Answer 3

You can use the ProcessBuilder class

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

Answer 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

Answer 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.

Answer 6

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

Answer 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
