How will we find that the cursor is now in that text field?
I have two text fields in Java. I want to write text in a text field but before writing text I want to check which text field is selected. How can I check it?
You can use isFocusOwner():
if(textField.isFocusOwner()) {
// the cursor is in the TextField
}

As you can see in the title i dont know how to make a java text field with text in the background that disappears when you click on it.
So theres a textfield that says "username" and when u click on it the username disapears and you can type in your password. Is it possible to do this without a new class?
my suggestion is to use swingx library and use JXTextField. so you can set the text using setPrompt method.
The situation is like this, first I set the text using the setText() function into the JTextField, then is it any way to retrieve the text that set into the TextField, I have already tried the getText() method, but the function get NOTHING from the TextField. Because my situation is complicated, so I must get the Text that set into the Textfield.
JTextField Jtf= new JTextField();
Jtf.setText("some value..");
String get = Jtf.getText();
I can't get the value that I set into the TextField, is there any solution for this? TQ.....
your code is right. text field should be instantiate in constructor check if not instantiate than do it, also check System.out.println(get), may you are doing wrong something.

Try to get access through getter. Like
public JTextArea getTextArea()
{
return jTextAreaField;
}
and then
getTextArea().append("ur text");

requestFocus() method of JTextfield will do.
