我试图制作一个调用外部程序的应用程序,我必须传递两个参数。它没有任何错误。用c ++编写的program.exe可以拍照并修改txt文件的内容。Java程序可以运行,但是什么也没做
这是我的示例代码
String[] params = new String [3]; params[0] = "C:\\Users\\user\\Desktop\\program.exe"; params[1] = "C:\\Users\\user\\Desktop\\images.jpg"; params[2] = "C:\\Users\\user\\Desktop\\images2.txt"; Runtime.getRuntime().exec(params);
从这里可耻地借来的
Process process = new ProcessBuilder("C:\\PathToExe\\MyExe.exe","param1","param2").start(); InputStream is = process.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line; System.out.printf("Output of running %s is:", Arrays.toString(args)); while ((line = br.readLine()) != null) { System.out.println(line); }
