用正则表达式验证普通车牌号格式

 

//车牌号格式验证
    String vehicleNoStyle = "^[/u4e00-/u9fa5]{1}[A-Z0-9]{6}$";
   Pattern pattern = Pattern.compile(vehicleNoStyle);
   Matcher matcher = pattern.matcher(txtvehicleNo.getText().trim());
   if (!matcher.matches()) {
    MsgBox.showWarning("车牌号格式不对！请认真填写！(字母必须大写)");
    txtvehicleNo.requestFocusInWindow();
    SysUtil.abort();
   }
