How to program this in java?
please explain steps, it has to come out like this:
example
input: 3b1w3b
output:
BBBWBBB

import java.io.*;
public class Test {
static java.io.PrintStream o = java.lang.System.out;
public static void main(String[] args)throws Exception {
     BufferedReader BR = new BufferedReader(new InputStreamReader(System.in));
     System.out.print("Enter plot for printing: ");
     String s = BR.readLine();
     char[] cs = s.toLowerCase().toCharArray();
     for(int i=0, j=0; i < cs.length-0x1; i+=0x2, j=0)
          while(j++ < (int)(cs[i]-0x30))
               o.print((char)(cs[i+0x1]-0x20));
I tried changeing it to this so I can enter my own string, but I want to change it some more so that it can enter multiple input separated by space, so that it can form a sort of picture line by line. I tried using tolkenizer but I get errors. I dont know how to use tolkenizer properly can anyone please TEACH. you dont have to tell how or give me the code if you dont want to. yes I know Im a noob and I dont know java as good as everyone here, If everyone thinks I don't deserve help then DON'T help, I'm just trying to learn programming

My iPad 1st is freezing up when i play games on it, anyone know how to fix this problem? Please Help

This is an ipad 2 it hasn't been updated, the thing is I restored it to the orginal setting because it was acting up, instead of 59.9 GB it gave me the memory capacity of 58.9 that has been already been use. Do you think using a different computer that hasn't been use on my ipad will raise the memory capacity? I've done it before just that the computer that I've been using has my ipad's data.

How to code this...please help

Hi Friends:
Please help me in coding the following scenario:
I've the following checkboxes on selection screen:
1. inventory quantity current period-unrestricted (mard-labst)
2. inventory quantity current period-restricted use stock (mard-einme)
3. inventory quantity current period-in quality inspection(mard-insme)
4. inventory quantity current period - blocked (mard-speme)
5. inventory quantity current period - returns (mard-retme)
6. inventory quantity current period- stock in transfer (mard-umlme)
now the scenario is like this. The user may check 1/2/3/4/5/6 checkboxes while executing this program. Now what all checkboxes are checked, only those values to be fetched from MARD. E.g. 1 & 2 are checked. Then I'll fetch labst & einme from MARD. Then I'll add it up. Please help me in coidng this. How to decide it at runtime.
Thanks:

Hi use this logic.
if c1 = 'X.
select single labst from mard into corrseponding table it_mard where..
endif
if c2 = 'X.
select single einme from mard into corrseponding table it_mard where..
endif.
if c3 = 'X.
select single insmefrom mard into corrseponding table it_mard where..
endif.
if c4 = 'X.
select single spemefrom mard into corrseponding table it_mard where..endif.
endif
if c5 = 'X.
select single retme from mard into corrseponding table it_mard where..
endif.
if c6 = 'X.
select single umlme from mard into corrseponding table it_mard where..endif.

I can't seem to compile this WebMail.java file. I have TomCat and servlets.jar is in my classpath too running but to no avail! Do u manage to compile and run it? Can u guys tell me what did I do wrong? Here's my list of errors(not all).

Direct link: ftp://ftp.wrox.com/Professional/2777/chap13.zip and a code snippet from that link:
import javax.mail.*;
import javax.mail.internet.*;
public class WebMail extends HttpServlet{..}The sample code is not OK, as it does not define where to find HttpServlet or things like HttpServletRequest. Then even if your classpath is allright, the compiler still does not know what is 'HttpServlet'.
If you look at http://java.sun.com/j2ee/tutorial/api/javax/servlet/http/HttpServlet.html you'll see that its full name is javax.servlet.http.HttpServlet. So either use the full names, like in
public class WebMail
extends javax.servlet.http.HttpServletand
public void doGet(javax.servlet.http.HttpServletRequest ...)or (preferred) simply add the following line at the top of your code:
import javax.servlet.http.*;Arjan.

Noob question, how to avoid this runtime error,please help..

Im new to java. Im using a JOptionPane in getting the user an input/a number, which is in String,. and to use it, im converting it by Integer.parseInt. When I run it everything seems ok, but whenever i inputted other data types other than integer(e.g char), i get a runtime error message "exception in main thread java.lang.NumberFormatException blah blah.....,. Is theres a way or a method or something that i can filter the users input when they type a character or when they inputted nothing that will not resulted to a runtime error, instead, an error message box will said that it is an invalid input. thanks in advance

Ah, well, after an evening of rest and reflection, I have to conclude that we are all partially correct. I never meant to imply that NumberFormatException should not be caught. I have had to repair too many classes in which just-in-case or programming-by-exception was a rule, rather than a valuable technique for handling exceptional or error situations.
As far as this example, I was not attempting to write a parser, or even start one. We are talking about a very simple situation ... determine if a String represents an integer. My example was overly simple, too. As pointed out, too simple. *\d+* would have eliminated empty strings, and with a few relatively minor changes, could handle all legal integers easily, including '-' and ',' characters, while excluding floating point and other invalid inputs. I did mention that regexes were an advanced technique. A Scanner could be used to test for the existence of an integer in a string. None of these rise to the level of parsing, IMO, but, as I have frequently said in these fora, the arguments of the mages are infinite. Of course, that implies that I consider myself a mage, which is not actually the truth.
In any case, as pointed out, this is an example where catching a runtime exception is probably a good idea, as long as we don't give the OP the idea that this is the only technique, or that code can be written to ignore the causes of exceptional situations, because we can always handle them in the catch block. I have seen way too much of this to be comfortable with even the suggestion of this.
I come here to learn. Sometimes, I learn interesting, complex things. Sometimes, I learn interesting, simple things.
Sincerely, thanks for helping me to learn.

How to write this application - URGENT PLEASE HELP

I would like to write a program for a supermarket loyalty card system. The program should have 2 customers and 2 gifts on offer. The customer details and the gift details can be hard coded.
When the program starts the user should be shown a menu which will have options to
view all customer details
add points for a customer
buy a gift
When the user chooses to buy a gift ro to add points, any changes made to the customers' points must be done using methods. Adding or buying gifts should be done using customer id's and gift id's.
The user must be able to see the altered points.
I WILL APPRECIATE IF I COULD GET HELP EVEN FOR PSEUDOCODE.

How to solve this trouble ? Please help me !

Hi everyone ! I'm fresher in c and c++. I'm having a trouble when I add new data into vector / list . I have a method like :
void List(vector<Student> &result)
ifstream list(saveurl, ios::in | ios::binary);
if (list.is_open())
Student st;
while (!list.eof())
if (list.read((char*)&st, sizeof(Student)))
result.push_back(st);
list.close();
First-chance exception at 0x5E84DF58 (msvcp120d.dll) in Student.exe: 0xC0000005: Access violation reading location 0x010FAA4C.
If there is a handler for this exception, the program may be safely continued.
what can I do now ? any suggestions for me ?

is it right ?
Perfect, as I suspected :)
Your Student class definition is just fine.
The problem is how you serialize that to/from files.
Since you have non-POD types like std::string as Student data members, you can't just dump your Student internal bytes to disk and read them back to disk.
This won't work, because for example std::string has pointers inside, and the values of those pointers (memory addresses) are meaningless when you write them to file and later load them from file, as just raw bytes, like in this code showed above in
this thread:
Student st;
while(list.read((char*)&st, sizeof(Student)))
You have to think how to write your Student class to files.
You can use XML, JSON, or even simple comma separated values text files.
Even if you use some custom binary format for your Student instances, you should pay attention to properly write the text stored in your strings to files, and read that back into std::string data members.

Try rebooting the iPad one more time. Try using recovery mode again and if that still doesn't work, make an appointment at an Apple Store and ask for their help.

I have ipod 4 touch. 3yrs old. when i plug in it isnt charging. it gets switched off after the charge gets over. then it charges and again switches on. dont know how to solve this problem.. please help

IPod 4 touch. 3yrs old. Not charging when plugged in. But charges when the battery gets drained. when battery gets over I keep it for charging. It switches on and doesn't charge.. Plz help!!;;

Not Charge
- See:
iPod touch: Hardware troubleshooting
iPhone and iPod touch: Charging the battery
- Try another cable. The cable for 5G iPod (lightning connector) seems to be more prone to failure than the older cable.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.

How to optimize this query? Please help

i have one table(argus) having 80,000 rows and another table (p0f) having 30,000 rows and i have to join both table on the basis of time field. the query is as follows
select distinct(start_time),res.port, res.dst_port from (select * from argus where argus.start_time between '2007-06-13 19:00:00' and '2007-06-22 20:00:00') res left outer join p0f on res.start_time=p0f.p0f_timestamp ;
the query is taking very large time . i have created index on the start_time and p0f_timestamp ,it increased the performance but not so much. My date comparisons would vary every time i have to execute a new query.
Plz tell me is there another way to execute such a query to output same results?
plz help me as my records are increasing day by day
Thanks
