I/O / Streams :: Not Receiving Correctly SMS Over Length Of More Than A Page Using AT Commands?
May 10, 2014
i m working on the SMS receiving using AT Commands using JAVA. i m getting the message of one page correctly using AT commands, but as i increase the size of SMS as 2, 3 or bigger pages the alphabets are converted to some thing like this
+CMGL: 0,"REC UNREAD","+923028910082",,"14/05/10,19:32:40+20"
4469616C202A3334352A393333232061757220536972662052732E3230206D65696E2

I have a binary file that has identifiers for the start of each record
You can see here that the record starts with 00 00 and the next record starts with 00 00 etc...
How do I read between these two points throughout the file?
RandomAccessFile database = new RandomAccessFile(databasePath, "r");
int start = 0;
int end = 0;
database.setLength(start);
database.seek(end);
The first start would be the start of the file, the next start would be the end of the first start and so on..
I'm just not sure how to put that into a loop.

Say I was to make a computer game, the first person to play the game would have a joinable game and would then be the server, and anyone joining in would be the client and the server was updated with JSON data of the clients computer game, and the server would then update each client of each characters new data using JSON, I would need fast multi threaded connection handling with minimum overhead, Is there a specific way to do this? or are there many?
I have realized there are a few ways to send and receive data using UDP and while experimenting I have also found its quite hard to synchronise.
Do I have a connection listening until there is data to be sent and then switched back to listening?
Do I have the server listening for a microsecond and then checking to see of there's anything to send for a microsecond continuously?
Do I have multiple connections for sending and receiving
Do I create new connections for each new and individual packets to be sent and received dynamically on a thread?
What is the optimum most effective way and do my examples reflect much understanding at all? my resent attempts create new problems and rather than re invent the wheel I would like to know what is normally done.

Keep getting a ParseException when I try to parse a ISO 8601 formatted String into a Java Date type.
String myDateString = "2014-07-04T22:59:36Z";
TimeZone timeZone = TimeZone.getTimeZone("UTC");
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm'Z'", Locale.US);
dateFormat.setTimeZone(timeZone);
Date formattedDate = dateFormat.parse(myDateString);
Keeps returning a ParseException:
Unparseable date: "2014-07-04T22:59:36Z"
What am I possibly doing wrong?

I would like my application to execute a command in cmd. The command looks like
start "" /D "C:Riot GamesLeague of LegendsRADSsolutionslol_game_client_sln
elease s .0.1.55deploy"
"League of Legends.exe" "8394" "LoLLauncher.exe" ""

So my question is how do I do this?
I tried this, (just copy paste the command):

public static void main(String[] args) {
try {

I'm using windows.. and our server is UNIX.. I knew that it's possible to create DOS commands in java programs, I have tried it already..
What I want to know is, is it possible to create a java program (from windows) that can execute UNIX command?
Something like: I have a java program in my windows, and it will create a directory in UNIX server /home/dir..
Based on my research, I can connect to our server in command prompt of my windows using ftp <domain> but the commands there is limited.

I have a Java application this application sits on a Dedicated server and gets information about the machine and run commands on the machine.
I need it so that i can run these commands from pressing buttons on a website. For example i press a button to retrieve CPU info, it goes to the app, and the app sends the CPU info back.
I'm fine with the website and app its just the middle bit. How do i get the app to run commands sent from a webpage. Been ratting my brains for a couple weeks now.

For a shool assignment i have to create a java irc client. which responds to commands. the !SENDMSG command has two parameters !SENDMSG <username> <the message>.
i can get the username and the message seperated, but i would like to create a check in case someone gives a bad command like: !SENDMSG" " <-- note te extra spaces, or if someone gives only 1 parameter.
else if (line.contains("!SENDMSG")) {
String str = line.split("!SENDMSG")[1]; //gives: <username> <the message>
String[] parts = line.split("s+");
if (parts.length >= 2) {
String user = parts[4]; //gives the <username>

String array[]={"sudo", "dolphin"};
Process proc = null;
try {
proc = Runtime.getRuntime().exec(array);

How I can insert password in this terminal? I tried write pass after array with commands and in, and even in outputstream.

My program is reading my file, but its printing out weird cryptic numbers instead of the 1-10 that is in the file. But it uses the numbers in the file to get the Max Value and Total. Also I am receiving 0 for my Minimum Value but, 0 isn't even in the file, my lowest value is 1.
Java Code: /*
* Student Name: Irrelavent
*
* Description: This program will read from a text file and display its contents in an array format as well as the average of the numbers and the minimum and maximum value within the array and it will display the total of all the numbers added together.
*
* Input Variables:
*
* Desired Output:
* Total: 55
Average: 5.5
Minimum Value: 1.0
Maximum Value: 10.0
The data being used is: [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0]
*/
[Code] ....
Output:
Numbers being used: [[I@55f96302]
---------------
Max Value: 10
---------------
Minimum Value: 0
---------------
Average: 0.0
---------------
Total: 55
I want 1 for my Minimum and I want 5.5 for my average, when I make 'average = total / numbers.length;' ---> 'average = total / (double)numbers.length;' I get 0.55. Also, as its obvious, my 'Numbers being used' section is messed up and I don't know whats causing this.

What I'm supposed to be doing is making it so the program can accept multiple filter and sort commands at one time, and each should be separated by a whitespace.I was thinking about parsing the input again, using whitespace as the delimiter, then normally progressing with each token, as though there was only one command.
However, coding this the way I'm doing it will firstly probably take hours, and secondly, it's likely not even right. I don't have any real way to determine which token contains which data from the Song objects.These are the specific requirements for this portion:A sort/filter command consists of one or more of the following options:
-year:<year(s)>
-rank:<rank(s)>
-artist:<artist>
-title:<title>
-sortBy:<field>
Any number of these options may be given, and they may be given in any order. If multiple options are specified, they will be separated by whitespace.
