The structure of a method's Code attribute is the following:

• attribute name (Code) and length
• max_stacks - maximum depth of the operand stack
• max_locals - number of local variables in the local variable array allocated upon invocation of this method, including the local variables used to pass parameters to the method when it is invoked
• the code - an array of opcodes (i.e., the instruction list)
• exception table - an array of exception handlers, each of which is represented by a quadruple: start_pc, end_pc, handler_pc and catch_type. The first two items describe the boundaries of the try catch block. The first three item are indexes in the code array, the fourth item is an index in the constant pool containing the exception class.
• attributes - an array of attributes
