Java compilers or JVM languages that support goto?

Question

Is there a java compiler flag that allows me to use goto as a valid construct? If not, are there any third-party java compilers that supports goto?

Answer 1

JVM support goto at bytecode level. If you are doing your own language, you should use libraries like BCEL or ASM, not generating .java file.

Answer 2

You can write your code generator to target Jasmin. You can use goto in Jasmin as much as you like. :-)

Answer 3

Java does not allow using goto keyword. However, it allows using labels and using break or continue with label instead of goto. In facts, Java is not a language without goto statement, but a language with uncomfortable implementation of it.

Answer 4

By definition, no Java compiler allows goto. Java compilers must implement the JLS, and the JLS does not allow gotos. However, it is also clearly possible to compile a language with gotos to the JVM. AMPC is one C-to-JVM compiler that claims to support C89.

Also note that Java bytecode has a goto instruction, though it's obviously instruction-based not line-based.

Answer 5

Apache Thrift can be used to generate source code in different programming languages from a single source. http://incubator.apache.org/thrift/

Answer 6

You shouldn't, ever, use goto, as it's EVIL ;-)

More seriously, maybe you could have a look at the famous article from E. Dijkstra : http://www.u.arizona.edu/~rubinson/copyright_violations/Go_To_Considered_Harmful.html
