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. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.
This direct access to the operating system paths can hinder the portability of programs. To support portable programs Java uses File.separator to distinguish between / and \ separated paths. Seed7 has a different approach for the path representation. In Seed7 all paths use the Unix path convention, independent of the operating system.
