Java呼叫exe

  		String cmd = "D:\QQ\Bin\QQ.exe";
        try {
        	//執行exe  cmd可以為字串(exe存放路徑)也可為陣列，呼叫exe時需要傳入引數時，可以傳陣列呼叫(引數有順序要求)
            Process p = Runtime.getRuntime().exec(cmd);
            String line = null;
            br = new BufferedReader(new InputStreamReader(p.getInputStream
 
()));
            brError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
            while ((line = br.readLine()) != null  || (line = brError.readLine()) != null) {
            	//輸出exe輸出的資訊以及錯誤資訊
                System.out.println(line);        
            }
        } catch (Exception
 
 e) {
            e.printStackTrace();
        } finally {
            if (br != null) {
                try {
                    br.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
