启动进程的两种方法

启动进程的两种方法

方法一：

public class QiDong0001 {
	public static void main(String[] args)throws IOException {
		
	
	ProcessBuilder pb = new ProcessBuilder("cmd","/c","ipconfig/all");
  //通过对象名调用start（）方法，创建一个新的Process实例（也就是说一个进程创建必须启动后才能使用）
	Process b = pb.start();
        //通过这两句代码来获取本机网卡的mac地址
	BufferedReader br = new BufferedReader(new InputStreamReader(b.getInputStream()));
	String s = null;
	while((s = br.readLine())!=null)
		System.out.println(s);
	}

方法二：

public class Qidong0002 {
	public static void main(String[] args) throws IOException {
		String s = "cmd "+"/c"+"ipconfig/all";
		Process p = Runtime.getRuntime().exec(s);
		BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
		String temp = null;
		while((temp = br.readLine())!=null)
			System.out.println(temp);
	
	}
