Example of using java to directly call a python script

Sometimes you need to use JAVA to directly call the python script to execute some server monitoring tasks. This article provides an example code for java to directly call a python script:

Import java. io. BufferedReader;
Import java. io. InputStreamReader;

Public class Main {
Public static void main (String [] args ){
Try {
System. out. println ("start ");
Process pr = runtime.getruntime(cmd.exe c ("python test. py ");

BufferedReader in = new BufferedReader (new InputStreamReader (
Pr. getInputStream ()));
String line;
While (line = in. readLine ())! = Null ){
System. out. println (line );
}
In. close ();
Pr. waitFor ();
System. out. println ("end ");
} Catch (Exception e ){
E. printStackTrace ();
}
}
}

If the following error is reported when running in eclipse:

Java. io. IOException: Cannot run program "python": CreateProcess error = 2
