This is a collection of various brainfuck interpreters written in Java. They use different methods and technologies and their execution speed varies. The FastASMBrainfuckInterpreter is the fastest Java brainfuck interpreter I know of (and twice as fast as Bff4).
Note that none of these implementations support the , operator.
The runtimes of the different interpreters on the mandelbrot.bf example:
| Interpreter | Time |
|---|---|
| Simple | 75088 ms |
| Adv | 20108 ms |
| JIT | 3092 ms |
| ASM | 2650 ms |
| FastASM | 2039 ms |
