您需要流程的OutputStream（InputStream）（并且应该使用ProcessBuilder）…就像这样
public static void main(String[] args) { String filename = args[1].substring(0, args[1].length() - 5); String cmd1 = "javac " + args[1]; String cmd2 = "java " + filename; try { // Use a ProcessBuilder ProcessBuilder pb = new ProcessBuilder(cmd1); Process p = pb.start(); InputStream is = p.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(is)); String line = null; while ((line = br.readLine()) != null) { System.out.println(line); } int r = p.waitFor(); // Let the process finish. if (r == 0) { // No error // run cmd2. } } catch (Exception e) { e.printStackTrace(); }}
