JAVA - JButton a odoslanie údajov

[MMartina]

Zdravím,
vedeli by ste mi pomôcť? Mám 2 Jframy a na prvom pri stlačení tlačidla si načítam číslo z JTextField ale neviem si ich rozumne uložiť alebo poslať do druhého JFramu, stále mi vráti hodnotu, ktorá tam je preddefinovaná nie tu zmenenú po stlačení tlačidla.
