1)Class文件是有8个字节为基础的字节流构成的,这些字节流之间都严格按照规定的顺序排列,并且字节之间不存在任何空隙,对于超过8个字节的数据,将按 照Big-Endian的顺序存储的,也就是说高位字节存储在低的地址上面,而低位字节存储到高地址上面,其实这也是class文件要跨平台的关键,因为 PowerPC架构的处理采用Big-Endian...
方法计数器,methods_count的值表示当前Class文件methods[]数组的成员个数。 methods[]: 方法表,methods[]数组中的每个成员都必须是一个method_info结构的数据项,用于表示当前类或接口中某个方法的完整描述。 attributes_count: 属性计数器,attributes_count的值表示当前Class文件attributes表的成员个数。 attributes[]: ...

Class类,Class类也是一个实实在在的类,存在于JDK的java.lang包中。Class类的实例表示java应用运行时的类(class ans enum)或接口(interface and annotation)(每个java类运行时都在JVM里表现为一个class对象,可通过类名.class、类型.getClass()、Class.forName("类名")等方法获取class对象)。数组同样也被映射为为...
