Talk:List of Java bytecode instructions

This is an old revision of this page, as edited by A5b (talk | contribs) at 03:28, 26 April 2013 (→hi (literally): Are there any updates to bytecode in Java 1 .. Java 8 ? `~~~~). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

This was originally in the java bytecode article, but got deleted there. Since there was some support to keep the list, and since there are similar listings for x86, it seems appropriate to have this article. This was basically copied from an older revision of the before mentioned article.

Updates

I just noticed this article and have made some changes to it to make it feel more consistent with other related Java Platform-articles. There is now a short introduction (as requested) and the template that is used by other Java-articles has been added to the bottom of the page. I may also suggest moving this article to another name like "List of Java bytecode instructions". It feels more propriate somehow.

Similarly, I have added a List of CIL instructions.

Sortable Table

I converted it into a sortable table to make it possible to see the instructions sorted by instruction code and by number of extra bytes. It works but is not perfect and I didn't find out how to get the following problems solved even though I tried a few things mentioned in Help:Sorting:

  1. The hex numbers should always be sorted as ASCII not numerical. Currently one needs to press the sort button 3 times to get a reasonable sorting of the hexadecimal values.
  2. I added the number of extra bytes at the beginning of all text in this row so that sorting makes sense. But I think it would be better if 3: were treated as less than 3/5: and 4: less than 4+:

Apart from that I'm not sure if the stack before/after column should better be split in two seperate columns that are independently sortable? --X4u (talk) 20:54, 18 May 2011 (UTC)[reply]

Hello world's bytecode

What does the bytecode for a hello-world app look like? 68.173.113.106 (talk) 23:34, 5 February 2012 (UTC)[reply]

You can write small java application and use the java disassembler, javap (this page also has some examples of bytecode).

JVM bytecode updates

Are there any updates to bytecode in Java 1 .. Java 8 ? `a5b (talk) 03:28, 26 April 2013 (UTC)[reply]
