Java – how to get the number of characters in jtextarea?

I have a jtextarea. I need to convert the character of each field to another character

So I thought of a simple cycle:

for(int i = 0; i <= t.length(); i++) { ... }

But the length () function is not appropriate. I can't find one

If someone has encountered this problem, I will help it

Solution

If you need the string content of the jtextarea field, just use textarea Gettext (), and then use the string as usual, for example, to get its length ()
