Hi,

if we assign a null to primitive data type
e.g:

javac throw an error.

but if we assign value using condition operation.
e.g:

then the javac is not throwing an error and it is throwing nullpointer exception in runtime

Note: On the same condition operation if we assign both as null.
e.g:
then it shows compilation error.

Could you please tell me what is the reason.

Hi,

I have enabled the taskbar's property "Group similar taskbar buttons" is on, in windows XP and my Java application which has multiple JFrame opened. Since it have more JFrame it tries to Group the similar one. Once it grouped then the taskbar icon for the application disappear and shows the default Java Icon.

I would like to know is there any way to set the application(custom) icon even it grouped.

Note: I did a google search and nothing helps and saw one java bug too. When I open multiple eclipse application it showing the eclipse icon properly. I think it can be possible to set.

Thanks in Advance.

Hi,

I want to perform the read and write the content operation in the file. For this I have created Serialized class to write and read from the file using ObjectInputStream and ObjectOutputStream. If I open and close every time its working fine. But every time open and close the file for read and write might be costly operation. I would like to know is there any better way to do this without closing the file for every time.

Thanks

Thanks you very much. I have started implementing my own custom collection class

one question here, when I use file better to keep the file stream object open for ever or open and close when ever it required.

Hi,

I would like to know is there any build in or third party collection class(to perform all operations in the collection interface) which can store the inserted items into the temp file if it exceeds the buffer size(e.g: 500). For e.g, if I am inserting 501 item into the collection class then it has to go into the file instead of having into the memory. While deleting the element in the memory, the element in the file has to be filled in the memory till it reaches the buffer size.

Thanks in Advance.

Thanks for your suggestions.

Chris Hurst ,

Could you provide sample program or tutorial to use the single object to signal between the thread.


I will also try "Jim Hoglund" suggestion given in the previous posts.

I have two list a, b. One thread is adding the data into the list and start the timer if the timer is not already started.



Another thread is a timer Task thread that will wake up for every 5 secs to read the list and process as follows.



Could any clarify my questions in the comments of the code. if my logic is wrong please provide the better way to implement to avoid synchronization issue.

You can construct the java.lang.File object and call the method getName() to get the file name.
