How can i convert strings placed in JtextField component into an integer

Question

I'm new to java and I have tried a lot in converting strings placed in a JTextField Component into an integer type, but I couldn't. So kindly help me with this problem.

But... JTextField isn't an Integer. What are you trying to achieve? — Halvor Holsten Strand, Jul 22 '14 at 17:52
@Ondkloss This is one more case of a badly redacted question where the title has more information than the post. He is referring to the string in the JTextField and not the JTextField itself. — DSquare, Jul 22 '14 at 17:54
btw, next time use [Google like this](https://www.google.com.mx/search?client=ubuntu&channel=fs&q=convert+string+to+jtextfield&ie=utf-8&oe=utf-8&gfe_rd=cr&ei=n6bOU7fQFMXB8AHLvYCwAg#channel=fs&q=convert+string+jtextfield+to+int) and that could lead you to: [Convert JTextField Input to Integer](http://stackoverflow.com/questions/11071211/convert-jtextfield-input-into-an-integer). — Frakcool, Jul 22 '14 at 18:01
On Execution i'll enter an integer in the JTextField and i need to process the entered integer later in the code... — user3865748, Jul 22 '14 at 18:06
Look at both answers below, also check both links I gave (if you haven't done that), if you need better help please post a [MCVE](http://stackoverflow.com/help/mcve) — Frakcool, Jul 22 '14 at 18:07
For the sake of common sense, use a `JSpinner` with `SpinnerNumberModel` instead. — Andrew Thompson, Jul 23 '14 at 02:29

Try the Integer.parseInt(java.lang.String) method.

int i;
try {
    i = Integer.parseInt(testField.getText()).intValue();
}
catch (NumberFormatException ex) {
    // FIXME Handle your exception!
}

I guess you're trying to parse the String got from the user input on JTextField and not the JTextField at all, so it should be something like this.

JTextField myTextField = new JTextField();

String textFromTextField = myTextField.getText();

int number = Integer.parseInt(textFromTextField);

System.out.println(number);
