※ 引述《zanyking (遥远的旅人)》之铭言： : ※ 引述《qrtt1 (thinking in java)》之铭言： : : == local q == : : 猜一猜、猜一猜、猜.......一...猜~~~~~~~~~~~~ : : 判断args有没有东西 : : 不可以用if(args==null) : : 要用if(args.length==0) : 这种的猜出来才有鬼... : 给一下source吧，不然只知道你对null作了些不合理的命令。 记得Local save 第一： 老实说看到後面有 at... 原po还不如把at... 贴上来 第二： 查了一下API对於Exception的解释 Thrown when an application attempts to use null in a case where an object is required. These include: * Calling the instance method of a null object. * Accessing or modifying the field of a null object. * Taking the length of null as if it were an array. * Accessing or modifying the slots of null as if it were an array. * Throwing null as if it were a Throwable value. 五种情形我这笨蛋都干过，还真猜不出你是指哪种错误 +_+ -- -- 嘿嘿..我是huge.. --
