Java Tune 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 (). EXEC ("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 you run the following error directly in Eclipse:
Java.io.IOException:Cannot Run Program "python": CreateProcess error=2
Configure the enviroment in the Run configuration to add the path variable, as shown in the attachment:

Call Process proc = Runtime.getruntime (). EXEC ("Python xx.py") in Java application; "xx.py directly under the project directory"

Use process proc = Runtime.getruntime (). EXEC ("Python xx.py") in a servlet in Tomcat; The results should be the Pyhon command can find (or directly enter the E:\\python\\python.exe absolute path) x.x.py file I was placed in the root directory, deliberately write the name incorrectly to xy.py. And the results are not responding "as if this statement did not execute"
= "should not be found in the py file. I searched the py file with an absolute path. Process proc = Runtime.getruntime (). EXEC ("Python d:\\xx.py"); that's OK.
"Current summary is the path problem of the py file"
