};
JFrame frame = new JFrame("SCJP");
txtField = new JTextField(20);

here i m dragging a radio and dropping that into a textBox, when i m dragging the radio button, my mouse pointer looks like (a rectangle and plus sign below the arrow).

What i need to do:

when i pick/drag the radio that time instead of that rectangle and plus sign, i want that string which is of radio?? i mean to say the radio button string/text i want as with my mouse cursor upto i drop that component/radio in text box..? please help me to figure out this problem as soon as possible, please.

First look here - this explains how to change the cursor while performing drag n drop. Once you understand the concept, you will have to code a method that creates an in-memory image of text from the radio button in question. That image can be used in populating the cursor.

Pseudo code:

img = //in-memory image created by writing text of radio button to graphics.
Cursor curCircle = Toolkit.getDefaultToolkit().createCustomCursor(img,new Point(5,5),"some text");

Set the new cursor in dragEnter - and then take care of dragExit to restore original cursor.
