You are setting the label text before the button is clicked to "txt". Instead when the button is clicked call setText() on the label and pass it the text from the text field.

Example:

label1.setText(nameField.getText());

the getText method returns a String  while the setText receives a String  so you can write it like label1 setText nameField getText     in your listener

Setup a DocumentListener on nameField  When nameField is updated  update your label   http   download oracle com javase 1 5 0 docs api javax swing JTextField html

in your action performed method  call   label1 setText nameField getText       This way  when the button is clicked  label will be updated to the nameField text
