Need Java code for random text.

To all you Java programmer Gurus out there.
How hard is it to make a small Java program whose whole purpose is to ask a user how many random characters they want and then proceeds to generate a text file full of RANDOM characters A-Z and a-z ?
The characters could repeat it does not matter as long as they repeat randomly.
I've found all kinds of code examples for Random password generators and things like that but none quite do what I want them to do.
sample of what the output file might look like
"fdfbgHBukOKiIkolpPkmNytTrFvDsVbNmNHyygrRDeDsSEfFGHGjJkjKKoJH"
Thank You kindly in Advance

I Need Java code for following Algorithm

* I Need Java code for following algorithm. Kindly any one help.
1. Read the contents (ideas and its corresponding scores) from two files named as 'a' and 'b'.
2. Stored the file 'a' contents in array a[].
3. Stored the file 'b' contents in array b[].
4. compare both files like
if(a.equals(b[j])
Writing the common idea and add the score from file 'a' and 'b'.
else
write the uncommon idea and its score..
For example :
Form Agents.txt
action,65
architecture,85
eco-,15
essay,30
form,85
form,85
link,40
tangent,25
Form Agents1.txt
Black holes,69
essay,78
Herewith i have above mentioned two files named as Form Agents and Form Agents1.
Form Agents has eight fields
Form Agents1 has two fields
--> 'essay' is common in two files, so store the idea 'essay' and add the score from Form Agents score is '30' and Form Agents1 has 78 (essay 108).
Finally it stores idea in another file with uncommon fields also.
Please help us.

We have tried with following code.
But we cant add the scores.
For Example:
Form Agents.txt --> has "essay,30"
Form Agents1.txt --> has "essay,78"
Result is: essay,108
Finally it stores idea in another file with uncommon fields also.
So Any one pls correct the following code.

I need Java code for a simple graphical hit counter for a webpage

I was wondering if anybody out there could send me some code for a simple graphical hit counter for a webpage. All the sites that I've visited are garbage and of no use to me. Please help me.
Colin

Not as easy as you'd imagine with applets. You need some way to store the hits, usually through a file on the server. That's not gonna happen in a hurry for 2 reasons -
- Applets can't read/write files
- Your web server usually won't let you run programs on their machine (ie, programs that listen for socket connections from applets, then load/read/write/close a file).
In short, no, there is no simple java solution (that I know of).

I need ready code for a simple paint program today

hi all I need ready code for a simple paint program today for me ics projct
plz give me a halp on this give me what you have with you and it is so good if it look like this :
Design a GUI based drawing Java application that works like a simple paint program
1-There should be a number of buttons for choosing different shapes to draw. For example, there should be a button for rectangle. If user presses the rectangle button, then he can draw a rectangle using mouse. Similarly, there should be a button for each shape(rectangle, circle, ellipse, and line etc.
2-The shapes can be filled with different colors.
3-There should be option of moving .
4- There should also be three menus including File, Shape, and Color menu.
i. File menu can have menu items New and Exit. If user selects New, the drawing area will be cleared and all shapes will be erased.
ii. Shape menu will serve the same purpose as of feature 2 described above. It will have menu items for drawing all the different shapes. For example, there will be menu item for rectangle; so user can draw a rectangle by selecting the menu item for rectangle.
iii. Color menu will serve the same purpose as of feature 3 described above. It will have menu items for all the colors which are shown in color buttons. The user can select a color from this menu and then click inside a shape to fill it with the selected color.

Read the Swing tutorial. There are sections on how to use menus and painting and all other kinds of stuff you need to do this homework assignment. Nobody here is going to write the code for you:

Hi,
it_wbs_prps1 .
If you are going to use this internal table to check for a null condition, shouldn't you first assign the data package to it?
For example,   it_wbs_prps1 = i_t_data[].
Because you are now using it_wbs_prps1 to select data from a table and it doesn't have any data.
Please check.
-RMP
Edit : Please ignore this. I didn't see that you are actually filling the internal table. Sorry!

Why I need a code for rent a film and where ist the code? (I dont have a card)

Why I need a code for rent a film and where ist the code? (I dont have a card)

it's unclear what you mean
you say you dont have a card which I guess is you don't have a creditcard
in which case the other option is to pay by a giftcard which include a code which you put in
because to rent you have to pay otherwise it's not really renting

Provide the java code for the following scenario.

Hi Experts,
I have tried with all the combinations for this scenario. As per my understanding i require java code for the following scenario
so that it becomes easy........
I require a Message mapping for this Logic.
In the Source there are 4 fields and, the Target side, the fields should appear like this.
Source Structure- File
Record
|-> Header
Order_No
Date
|-> Item
Mat_No
Quantity
Target Structure-IDoc
IDoc
|-> Header
|-> Segment
Delivery_Order_No
Recv_Date
|-> Item
|-> Segment
Delivery_Order_No
Material_Num
Recv_Quantity.
The Logic is for every Order number an IDOC is generated.And if the Material num matches then the quantity should be added. and important note is that the material numbers are different for every order number. That means if a material number is 2 in the order number A. Then the material number can never be 2 in any of the order numbers.Here is the following with an example for the above scenario.
For example:-
we have
Source Structure- File
Order-no Date Mat_No Quantity
1 01/02/2011 A 10
1 01/02/2011 B 15
1 01/02/2011 A 10
2 01/02/2011 C 10
2 01/02/2011 C 10
3 01/02/2011 D 20
3 01/02/2011 D 10
3 01/02/2011 E 25
Target Structure-IDoc
Delivery_Order_No Recv_Date Material_Num Recv_Quantity
1 01/02/2011 A 20
1 01/02/2011 B 15
2 01/02/2011 C 20
3 01/02/2011 D 30
3 01/02/2011 E 25
So for this example total of 5-Idocs created. That means for this example if Order_No is 1 When the Mat_No is A the quantity gets added. For this Scenario 1 IDoc with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) is generated by adding the quantity field in the Target Side. Similarly if Order_No is 1 when the Mat_No is B then separate IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) in the Target Side. Similarly, if Order_No is 2 when the Mat_No is C, an IDoc is generated with four Fields 2 in Header(Delivery_Order_No, Recv_Date) and 2 in Item(Material_Num, Recv_Quantity) by adding the quantity field in the Target Side. ike wise the process goes on upto 3.Kindly do the needy..
Kindly provide the java code.
Thanq very much in advance..

what i have understood from ur example is that u want to generate an idoc for unique combination of Order-no and Mat_No
if yes then chk the below mapping..
change the context of Order_No, Date, Mat_No and Quantity to Record (right click-> context)
1)
Order-no
----------------------concat[;]---sort----splitbyvalue(valuechanged)-----collapse context---IDoc
Mat_No
2)
Order-no
--------concat[;]---sort----splitbyvalue(value changed)---collapse context---UDF1--splitbyvalue(each value)--Delivery_Order_No
Mat_No
3)
Order-no
-----------concat[;]---sortbykey----------------------- \
Mat_No                       /                            \
Date--------------- /                                       \
----------------------------------------------------------FormatByExample-----collapsecontext---splitbyvalue(each value)----Recv_Date
Order-no                                                 /
-----------concat[;]---sort----splitbyvalue(value changed)
Mat_No
4)
Order-no
--------concat[;]---sort----splitbyvalue(value changed)---collapse context-UDF2--splitbyvalue(each value)--Material_Num
Mat_No
5)
Order-no
-----------concat[;]---sortbykey
Mat_No                       /
Quantity --------------- /
----------------------------------------------------------FormatByExample-----SUM(under statistic)----Recv_Quantity
Order-no
-----------concat[;]---sort----splitbyvalue(value changed)
Mat_No
UDF1:
String [] temp= a.split(";");
return temp[0];
UDF2:
String [] temp= a.split(";");
return temp[1];
