[Python知识库]java调用python

注意点：
1.保证python能用命令行执行
2.python里的路径必须是绝对路径。（重要）

public class Demo1 {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Process proc;
        try {
            proc = Runtime.getRuntime().exec("python C:\\project_of_python\\people_face\\train.py");
            
            BufferedReader in = new BufferedReader(new InputStreamReader(proc.getInputStream()));
            System.out.println(in.readLine());
            String line = null;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
            in.close();
            proc.waitFor();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
