How to use TextField to add two numbers and show the result.

Question

hi everybody
i would like to use JTextField to get addtion of two Numbers,
for example i am trying to type any integer numbers in JTextField like 7
and press JButton, called( +) to add anthor number like 7 and press JButton called(=) to get addtion fo
7 + 7 = 14, at same JTextField.
so there will be two buttons, one for (+),other for (=).
i have implement ActionListener in (+) button ,to get Text from JTextField (with getText() method),
now how do i use same getText() method to get the next number that i will add it with previous number in
(+) button and get the result whenever i press (=).
1-type integer number like (4) in TextField.
2-press addition button(+) to get text by using getText() method and clear TextField.
3-type anthor integer number like(6).
4-press (=) button to get the number (6) by using getText() method, calculate 4 + 6 and show the result at same TextField (10).
i hope it is so clear
thank u in advance for any advice and suggestion.

Answer 1

Use your first button to
String x = JTField.getText();
int y = Integer.parseInt(x);
this will get your first value on your + button. Make sure you initialise the int beforehand incase nothing is put in (ie error prevention) then clear the JTField prob using setText(""). Repeat the process for the = button using different variables and add them normally and output the result.
If your putting more than 1 arithmetic button on the GUI then you'll need to distinguish between them!!!
