Multiple JTextFields?

Question

I'm confused if you can have more than 1 JtextField inside of a single JPanel? If yes, then how with the code provided below.

my code:

private JPanel jp;
private JTextField jt;

jt = new JTextField();
jt.setBounds(1, 25, 60, 20);
jp.add(jt);
jt.setColumns(10);

JLabel npcId = new JLabel("npcId");
npcId.setBounds(15, 11, 92, 14);
jp.add(npcId);

What I'm building:

enter image description here

What I'm trying to accomplish here is have 5 JTextField objects: npcId, npcLocation, npcReg, npcAH, npcAA.

Please take a look at the documentation related to Swing Layout Manager http://docs.oracle.com/javase/tutorial/uiswing/layout/using.html It is very flexible way to control position of GUI elements — XZen, Nov 28 '13 at 06:01
`Don't use setBounds().` Where ever you found that example get rid of it. You should be using layout managers as suggested above. — camickr, Nov 28 '13 at 06:03
Java GUIs might have to work on a number of platforms, on different screen resolutions & using different PLAFs. As such they are not conducive to exact placement of components. To organize the components for a robust GUI, instead use layout managers, or [combinations of them](http://stackoverflow.com/a/5630271/418556), along with layout padding & borders for [white space](http://stackoverflow.com/q/17874717/418556). — Andrew Thompson, Nov 28 '13 at 06:05
I was going off what I read in a java doc like a year ago & I couldn't find the book I saw it in, lost it in my house somewhere. But @ john I've tried copying npcId & changing it... failed. — Ryan, Nov 28 '13 at 06:06

Yes, it's very easy, you need to make use of an appropriate layout manager.

Take a look,at A Visual Guide to Layout Managers

I might suggest starting with something GridLayout, but eventually, you'll want to look at GridBagLayout.

Don't forget, you can use compound layouts to create sophisticated layouts

Also, you might consider those basic methods:

// Use of Textfield
usernameField = new JTextField(8);
usernameField.setLocation(0, 0);
usernameField.setSize(100, 30);

So `jt = new JTextField(); jt.setLocation(0,0); jt.setSize(100, 30);` how would I go about duplicating that to make more text fields....? – Ryan Nov 28 '13 at 06:25
for example `jt2 = new JTextField();` etc. – Simon Nov 28 '13 at 06:30

Yes you can it easily, what you realy have to is 1) declare all your JTextFields like :

jt = new JTextField();
jt.setBounds(1, 25, 60, 20);
jp.add(jt);
jt.setColumns(10);

2) declare your JPanel like

private JPanel jp;

jp = new JPanel();// here you have to set a layout manager for this panel
//for exampl:
jp.setLayout(new FlowLayout());

check the Layout Managers from here.

3) add all declared JTextFields to your panel :

jp.add(jt);
jp.setVisible(true);
