首先，你第一句就返回了，程序就不会执行下面的语句了。二，你定义的一个名为e的异常，但它是空的。（没有捕获）三，java中有获取变量/常量必须赋值，不然会报楼上的"AssignmentOperator Expression "错误 楼主如果是getProperty()有可能报异常的话，应该要这么写 try{ //有可能报异常的代码 ...

One of the most common operators that you'll encounter is the simple assignment operator "=". You saw this operator in the Bicycle class; it assigns the value on its right to the operand on its left: int cadence = 0; int speed = 0; int gear = 1; This operator can also be used...
