{{Main|Java bytecode}}

This is a list of the instructions that make up the [[Java bytecode]], an abstract machine language that is ultimately executed by the [[Java virtual machine]].<ref>{{cite web|url=https://docs.oracle.com/javase/specs/jvms/se12se24/html/index.html |title=The Java® Virtual Machine Specification – Java SE 1224 Edition |access-date=MayJuly 2226, 20212025}}</ref> The Java bytecode is generated from languages running on the [[Java Platform]], most notably the [[Java (programming language)|Java programming language]].

''Note that any referenced "value" refers to a 32-bit int as per the Java instruction set.''
