因为java是强类型语言,所以判断空的时候分null 和字符串空if(userID == null || "".equals(userID)){ response.sendRedirect("login.jsp?errorType="+Utility.encrypt("1")+"&userID="+userID); return; }

【每天1分钟】PYTHON基础之异常处理(捕获异常) 1. 基本语法try: # 尝试执行的代码 ... except ErrorType as e: # 针对"该错误" 的处理代码, 可有多个except ... else: # 没出现异常时,才需要运行 ... fina
Python 异常处理 异常处理块 python 支持异常处理,使用 try 块进行异常处理,异常抛出和捕获的进制和 Java 的 try-catch-finally 块很相似,语法如 下: try: <statement> except ErrorType: <handle error statement>
