import java.io.BufferedReader; import java.io.InputStreamReader; public class cmd { public static void main(String[] args) { BufferedReader br = null; try { Process p = Runtime.getRuntime().exec("cmd.exe /c ipconfig /all"); br = new BufferedReader(new InputStreamReader(p.getInputStream())); String line = null; while ((line = br.readLine()) != null) { System.out.println(line); } } catch (Exception e) { e.printStackTrace(); } finally { if (br != null) { try { br.close(); } catch (Exception e) { e.printStackTrace(); } } } } }

import java.io.BufferedReader; import java.io.InputStreamReader; public class cmd { public static void main(String[] args) { BufferedReader br = null; try { Process p = Runtime.getRuntime().exec("cmd.exe /c ipconfig /all"); br = new BufferedReader(new InputStreamReader(p.getInputStream())); String line = null; while ((line = br.readLine()) != null) { System.out.println(line); } } catch (Exception e) { e.printStackTrace(); } finally { if (br != null) { try { br.close(); } catch (Exception e) { e.printStackTrace(); } } } } }

我如果要输入：netsh wlan connect name="503" 呢？ipconfig好像是cmd命令可以直接这么运行，但是我改成我想要输入的数就不行了！

Runtime run = Runtime.getRuntime(); run.exec("cmd命令");

可以啦 谢谢

想调cmd命令直说就好了,干嘛装的这么委婉
