[eug-lug]little programming challenge

[Larry Price]

Neil popped this one on the clinic,

can you write a function in java that does the equivalent of this 
python script

-------snip--------
#!/usr/bin/python
def swap(a,b):
    return b,a
a = 'foo'
b = 'bar'
print a,b
a,b = swap(a,b)
print a,b
------snap---------
turns out to be surprisingly difficult ;-)



This is a Signature: Someday soon it will have clever sayings and URL's
