1. Write a simple class with a
main()
method that prints out the arguments
supplied on the command line used to invoke it. First use a
for
loop to
do this, then a
while
loop, then a
do-while
. What differences do you
notice? Which do you find most amenable for this task?
2. Modify the previous class to quit echoing its arguments should it en-
counter an argument of length 5. (You can tell the length of a
String
object with the
length()
method, e.g.,
mystr.length()
.) Did you use
break
, or
continue
, or some other mechanism?
