java直接调用python脚本的例子

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();
  }
 }
}

如果在eclipse中直接运行报如下错误：

java.io.ioexception: cannot run program "python": createprocess error=2

则配置run configuration中的enviroment，增加path变量，见下图：
