How to pass JTextField from JFrame into another JFrame in Netbeans GUI

sorry for asking again cause i didn't understand it clearly.. and still
not figuring it out When I input First Name, Last Name and other
information in the JTextField of JFrame1 and then click button next, the
inputted data will display all inputted data on last JFrame.

please need help... please gave me sample just Username then pass it into
other frame jLabel it's hard to find tutorials...
just gave me this sample
Frame 1(Input Value) I input on textbox named username then click next
Frame 2(Display Inputted on Last Frame) Display inputted data on last
frame named 'username' into jLabel hope I understand this time.
