goto instruction

This article is based on Zhou Zhiming's "in-depth understanding of Java virtual machines"The instructions for a Java virtual machine consist of a byte-length opcode that represents the meaning of a particular operation (Opcode) and 0 to several

The Java Virtual Machine directive consists of a byte length, an opcode (Opcode) that represents a particular meaning, and the following 0 to many operands representing this action parameter. Many of the instructions in the virtual machine do not

If for different situations, need to perform different established operations, if or according to the normal execution process, is unable to complete the task, this time, it is necessary to introduce the concept of process jump, using the process

A Java VM instruction is composed of an Opcode with a byte length that represents a specific meaning and a zero number that represents the operands of this operation parameter. In a virtual machine, many commands do not contain operands, but only
