前提：
1. sun-jre1.6, jython 2.5
2. 在官网下下个jython_installer-2.5.0.jar，一路next, 在 /jython-install-path/里有个jython.jar, 把这个jython.jar import 进Java Project 里边。
python代码: fibo.py
- # Fibonacci numbers module
-
- def fib(n): # write Fibonacci series up to n
- a, b = 0, 1
- while b < n:
- print b,
- a, b = b, a+b
-
- def fib2(n): # return Fibonacci series up to n
- result = []
- a, b = 0, 1
- while b < n:
- result.append(b)
- a, b = b, a+b
- return result
Java 代码：TestJython.java
