// 创建系统进程

ProcessBuilder pb = new ProcessBuilder("tasklist");

Process p = pb.start();

BufferedReader out = new BufferedReader(new InputStreamReader(new BufferedInputStream(p.getInputStream()), Charset.forName("GB2312")));

BufferedReader err = new BufferedReader(new InputStreamReader(new BufferedInputStream(p.getErrorStream())));

System.out.println("Window 系统进程列表");

String ostr;

while ((ostr = out.readLine()) != null)

System.out.println(ostr);

String estr = err.readLine();

if (estr != null) {

System.out.println("\nError Info");

System.out.println(estr);

}

}
