Thank you very much. I am reading it.

A simple code from the book. Why it use applet.repaint() instead of applet.paint() in the listener? paint() is a public method in class Dots, why I cannot do applet.paint() in which applet is an object of class Dots. -------------------------- import java.applet.Applet; import java.awt.*...

Thanks a lot for your help.

OK, it passes the value of the reference, not the value of the object into a method. When the new reference (in the mothod) pointes to another string object the original reference remains pointing to the original object.

Hi, I am confused by Events and Listeners because I know VB. Why VB can work without Listener?

sedj, Thank you for your response. If a String is unchangeable, there must a copy of the string, not the copy of its reference, in the above method (so that it can be changed in the method while not affect the string in the main). That means an object (the string) is copied in the method!

Thank you for the interesting links. However, still need your explanation: A string is an object? In the above method, static String test(String s), s is the reference of a String? Any change of s in the method will change the value of s in the main?

Hi, This should be very simple, but I am a beginner. 1. An object is passed to a method by reference? 2. A string is an object? 3. Hence, a string is passed to a meshod by reference? public class Try { public static void main(String[] args) { String s="222222"...

Hi, When I leave my computer for a while, the light of the hard disk will be very busy until I come back and do something. Anything wrong?

Put my mouse cursor in following Sub and then press F5, I can run it: Private Sub try() MsgBox "aaaaa" End Sub It can fire "Sub objItems_ItemAdd(ByVal Item As Object)" when new email comes.

Or try this: Data is in Column A. In column B2, enter this formula: =LEN(A2) (assuming row 1 contains header data) and copy down the formula. Then sort by column B,A.
