我正在阅读章节6. The Java Virtual Machine Instruction Set
当我阅读下面摘录中的“操作数堆栈”时，我不确定如何解释该部分。特别是箭头，是栈内、栈外的意思吗？

Operand Stack
..., value1, value2 →
..., value3
Description
A longer description detailing constraints on operand stack contents or constant pool entries, the operation performed, the type of the results, etc.
最佳答案
我想这在“注释”部分中有解释:
In the description of the Java Virtual Machine instructions, the effect of an instruction's execution on the operand stack (§2.6.2) of the current frame (§2.6) is represented textually, with the stack growing from left to right and each value represented separately. Thus,
..., value1, value2 →
..., result
shows an operation that begins by having value2 on top of the operand stack with value1 just beneath it.
