process - Call Python from Java -

i want call python script java. python version 2.5 , java 6.

my current code:

try{     process p= runtime.getruntime().exec("path/dirs/file.py");     p.waitfor();     } catch (interruptedexception ex){     system.out.println(ex.getmessage());}     }

try use precessbuilder -

try{     string prg = "import sys\nprint int(sys.argv[1])+int(sys.argv[2])\n";    bufferedwriter out = new bufferedwriter(new filewriter("test1.py"));    out.write(prg);    out.close();    int number1 = 10;    int number2 = 32;     processbuilder pb = new processbuilder("python","test1.py",""+number1,""+number2);    process p = pb.start();     bufferedreader in = new bufferedreader(new inputstreamreader(p.getinputstream()));    int ret = new integer(in.readline()).intvalue();    system.out.println("value : "+ret); }catch(exception e){system.out.println(e);}
