Re: NoSuchMethodError because of signature?

[Peter Dow <petercdow@xxxxxxxxx>]

Ok, got it. I copied and pasted from Gary's post.  But when I compiled...

testjava.java:18: cannot find symbol
symbol  : class StringÕþ
location: class testjava
    public static void main (StringÕþ argv) {
                             ^
1 error

Sorry to bug you guys with this beginner's stuff. I'm assuming those are 
square brackets, [ ], after String, right?  It looked ok (i.e. like 
square brackets) in edtf (ccsid 437), but just in case, I changed the 
file's ccsid to 1252 (not sure how it got to be 437) and then it looked 
like the above. I re-keyed it as [ ] and tried compiling again. Now it says

testjava.java:18: illegal character: \168
    public static void main (String[] argv) {
                                    ^
testjava.java:40: ')' expected
}
^
2 errors

which now looks right, but it's still complaining.
