前言：
今天大家对“java 调用”大致比较重视，大家都想要知道一些“java 调用”的相关文章。那么小编同时在网上汇集了一些有关“java 调用””的相关知识，希望同学们能喜欢，同学们快快来了解一下吧！public void runProcessDemo1 { try { Process process = Runtime.getRuntime().exec("ipconfig /all"); InputStream is = process.getInputStream(); InputStreamReader isr =new InputStreamReader(is, "gbk"); BufferedReader br = new BufferedReader(isr); String line; while ((line = br.readLine()) != null) { System.out.println(line); } int exitCode = process.waitFor(); System.out.println(exitCode); } catch (IOException | InterruptedException e) { e.printStackTrace(); }}public void runProcessDemo2 { ProcessBuilder processBuilder = new ProcessBuilder(); processBuilder.command("ipconfig","/all"); //将标准输入流和错误输入流合并，通过标准输入流读取信息 processBuilder.redirectErrorStream(true); try { //启动进程 Process start = processBuilder.start(); //获取输入流 InputStream inputStream = start.getInputStream(); //转成字符输入流 InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "gbk"); int len = -1; char[] c = new char[1024]; StringBuffer outputString = new StringBuffer(); //读取进程输入流中的内容 while ((len = inputStreamReader.read(c)) != -1) { String s = new String(c, 0, len); outputString.append(s); System.out.print(s); } inputStream.close(); } catch (IOException e) { e.printStackTrace(); }}public void runProcessDemo3 throws IOException { ProcessBuilder processBuilder = new ProcessBuilder("cmd","/c","dir"); processBuilder.directory(new File("D:/")); Process process = processBuilder.start(); BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), "gbk")); String line; while ((line = br.readLine()) != null) { System.out.println(line); }}以上均是windows平台，如果是Linux，请使用相应命令。
