Agreed with Ezzaral, Check Line 32, you are using a variable without even intializing it. Check this page out http://www.javaworld.com/javaworld/jw-03-1998/jw-03-initialization.html?page=2.

Is there any way to extend gaps between jmenuitem?

Seems like u want to abort a thread cleanly if it fails to complete in a desired time. I think "interrupt" is one of the possible way's, u need a exception handler in which u can print a message or empty as u desire....

Print out the original string u got

System.out.print(userString);

Sorry, but i thought no answers from here so i posted some where to get my answer....

I just found table model listener.... And it solved a great deal of my problem. But Still i cant select a new cell for updation, each cellEditAt call tablemodelevent function call which iterate and generate a error... Any Help Regarding to this...

if(table.getSelectedColumn() == 3 && table.getSelectedRow() != -1 && tme.getType() == TableModelEvent.UPDATE)
table.editCellAt(table.getSelectedRow() + 1, 0);			{

if(table.getRowCount() >0)
if(table.getSelectedRow() == (table.getRowCount() - 1))	
table.editCellAt(0,3);
else
table.editCellAt(table.getSelectedRow()+1,3);

Well its the code in public void keyReleased(KeyEvent ke)

And its not working, i will post a video to make it more clear... Problem is it select next cell for edit but when it reaches to end it select the first row and after VK_ENTER it move from column 3 to 4, Thats my problem...

Well i want to edit a cell and when a user press enter next cell automatically selected in edit mode.... Its just a name entering form , when data is entered in one cell cursor moves to next.

These lines are in mouse clicked method... Problem is when it reaches to end, and when fw button is pressed it jumps to another column.... Any Suggestions;.....

Please help me with my sub netting concept...

what 10.2.1.1/9 mean?

I think the program you were going to create is the most simple for you. Also try to build a calculator, or a notepad.

1) Use i++ at the end, If you want to show user that please enter value one then use i+1 in print statement.
2) You need to set size for integer array before using it, int a[] = new int[6] // because you want to store 6 values
3) Take input in each array position a[position] = someintvalue
4) use for loop to print them all.
:)

You must have a cipher text and its original text (If You are Lucky)
Try Brute Force with different keys (Work 100% But takes alot time)
Try Intelligent Search for key (Require some data about the key)

Authors values for setSize is Correct, it correctly display the frame and its component. While choosing a fixed size frame Author possibly tried a value then improved it further until the display become correct..
I myself tried fixed values many times and reaches to conclusion after trying some values... :)Well any one has better trick please guide me then.
