    解析： 对原始数据类型的变量的声明将为之分配内存并赋予一个缺省值，参见23题的叙述，而非原始数据类型的变量必须用new Xxxx()分配内存及初始化。但是严格来讲此题的答案有待确定，因为只有原始类型的实例变量和类变量的声明在类对象被创建/类被加载时完成内存的自动分配，而原始类型的局部变量必须显式初始化，从这点来看原始类型的局部变量没有被自动分配内存，SL275中只提出了非原始数据类型的变量必须使用new Xxxx()完成内存的分配而没有指出原始数据类型的变量是否在声明时即自动进行内存分配，而从局部变量不能在显式初始化前使用这点来看在声明时没有进行内存分配。因此答案a的正确性还有待官方的确定。
