If the problem exactly is to get the data from the TextArea you have to use "getText()".
Also mention number of rows and columns that the TextArea should contain while defining Text Area.
JTextArea t = new JTextArea(5,10);
This statement creates the TextArea with 5 rows and 10 cols.
In order to get the data entered in the TextArea when the button pressed, use the following statement in "actionPerformed()".
String str = t.getText();
