java中如何调用.bat程序

其实只要在字符串前加上cmd  /c start就可以了

public class Test {

    static public void main(String[] args) {
        String cmd = "cmd /c start C:/WSCA-ENU-06-12/setpassword.bat";

        try {
            Process ps = Runtime.getRuntime().exec(cmd);
            System.out.println("2");
            System.out.print(loadStream(ps.getInputStream()));
            System.err.print(loadStream(ps.getErrorStream()));
        } catch(IOException ioe) {
            ioe.printStackTrace();
        }
    }
