Java调用exe示例

Java调用exe

  		String cmd = "D:\QQ\Bin\QQ.exe";
        try {
        	//执行exe  cmd可以为字符串(exe存放路径)也可为数组，调用exe时需要传入参数时，可以传数组调用(参数有顺序要求)
            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) {
            	//输出exe输出的信息以及错误信息
                System.out.println(line);        
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (br != null) {
                try {
                    br.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
