ok, i'm new to java, and i can't figure out if i'm retarded or if is there no length/size method for arrays, at least for string arrays

Do you want the length of a string, or the length of an array of strings?

[Anonymous No.1042913]

String a = "astring";
int length;

length = a.length()

>>1042907

the length of an array of strings

and there also seems to be almost no methods for arrays, what's that all about?

[Anonymous No.1042926]

I have a whole roll of string, I can make whatever length string I want!

If you can't understand the documentation, then here:

String[] s = {"abc", "fgs"};

Array.getLength(s);

And /sci/ is what?
Are you trying to imply /sci/ is less stupid than /g/? How can you beleive it if it's just a theory (a geuss)?
