getPassword() returns char[] so use .length field

jPasswordField1.getPassword().length

Why is char[] preferred over String for passwords?

that method is depricated, see http://stackoverflow.com/questions/8881291/why-is-char-preferred-over-string-for-passwords why it is preferred to use getPassword() instead – jmj Sep 05 '13 at 06:00

Try

jPasswordField1.getPassword().length

getPassword() returns char[]. See docs.
