Question

I have this code

lStock.setText(" Put " + getLoc(i));

At the moment it prints out like this on the GUI:

3I031C

what I want to show now on the screen GUI is:

3I03-1C

I tried testing the split() but I’m confused.

Answer 1

You can’t use the split method since it needs a delimiter, but you’re string doesn’t contain any.

You can try using substring:

str = str.substring(0, 4) + "-" + str.substring(4);

But this will only work if the string always have the same length and format.
