I need to generate a file in Java with Unix TimeStamp. Want to generate an ordered list of Data entry objects for a defined period of time e.g., getData (long startTimeStamp, endTimeStamp, long resolution).
1) I would like to generate resolution with random numbers by using Random class.
2) How to take Start and end timestamps to generate a file (i.e., writing into a file).
I am creating a web application that runs on server X(unix) and it has another unix system mounted on it. I want to generate the file tree structure of this mounted unix file system and show it on to a web application so that users can select a file and move it onto this current unix machine.
I know this sounds stupid and you may want to say why cant we directly copy the file, I am doing a proof of concept and using this as a basis.
I have a requirement to convert 'unix time stamp' to 'Date time format'
Input (Unix time stamp) : 1426013480000
Output should show : 3/10/2015 2:51 PM EST (or) 10th March 2015 2:51PM EST
I have a unix program that simulates an accident evolving as a function of time and produces two files. I will focus on the first file before getting to the second. This first file has five output variables/vectors (velocity vs time, pressure vs time, etc), which are selected as part of the simulation input. These are the variables I have to put into Excel if I want to view the transient graphically. Where it gets tedious is that, if I want to view a different set of five variables, I have to rerun, extract, put these in Excel to plot. There can be lots of variables needed to properly characterize the accident.
The second file produced is a really large binary file. This file contains all the information that I'd need, precluding the need to rerun to view a different set of output variables. This is the file that seems tailor-made for a Java or something to be able to extract the information. That is, it seems like Java could be used to do this work: extract variable information from the large binary file. Eventually, I would like to plot it too and I know I could use Java there.
I think my steps are:
1) understand the format of my binary file
2) reconfigure the binary file for use with java (is this demuxing?)
3) learn java programming for this application: extracting information to produce something like a .csv file with time on the leftmost column and variable information populating the rest of the columns.
I read and then copy files into a subfolder, and I need to rename the file names by adding the timestamp to the file name, for example like: "filename1_25.06.14_15:00:00.txt". How can I do that? Here is what I have:
public class Table_data {
static String files = null;
static List<O> l= new ArrayList<O>();
[Code]....
is it right what i tryed, because i get nothing with timestamp in file after running this.
I have a requirement to get the details of the files present in a directory on a server. I need to get the file names and timestamp. I have the below code to get the file names:
Connection conn = new OracleDriver().defaultConnection();
ArrayDescriptor arraydesc =
ArrayDescriptor.createDescriptor ("DIRLIST_T", conn);
File myDir = new File (dir);
String[] filesList = myDir.list();
ARRAY dirArray = new ARRAY(arraydesc, conn, filesList);
return dirArray;
But am not able to get the timestamp. How can I get the timestamp as well.

I have a given WSDL file (around 1MB) and inside of the file they have many request and response types.
I have to generate JAR from it so I could import it on my current project and use it
I have tried using this: [URL]....
but it only generated 1 stub file and a 1 callback handler java files and its size is around 60MB.
WHat I need to is to generate seperate class file per response / request type... Is there a way to do it?
I have a requirement where I have to send a file from a local system to unix box(present on client side) using java code.I have developed a code that is successfully sending the file from local system to client side unix box (I am connecting to client side unix box using VPN) provided I run the code in my eclipse IDE present in local system. But when I am running the same code in the unix box it is throwing null pointer exception.Might be the unix system is not recognising the local system. Please find the code.

I have been doing a project of ERP solution using JAVA AWT FRAMES and MYSQL(for database purpose). Here there is an ADMIN portion, who has the authority to make PAYROLLS of individual employees. There is a Frame where individual employee details will be shown(like basic salary, HRA, no.of leaves, other allowances...etc) in text boxes.
Now what i want is to make a PDF file of that payroll, so that I can make a hardcopy of it. The idea is just like anyother online form fill-up, where at the end you submit and save (or export) as a PDF (or text file) document. But I mention that it is a stanalone project, not an online one (i think it doesn't matter though).
So the basic idea is how to make a PDF file by extracting the text field or choice contents from a frame in JAVA AWT.
I have an application separated into three different projects - core, command line version and Web UI version.
Core contains all the business logic in several services classes. Command line version and Web UI version both uses the core project services.
Command line have main class which call services from core. Web UI version is Spring base application using same services from core.
Java Code:
CoreProject
- src
- Service Classes (code here use thirdParty jars and core_file.txt)
- lib
- thirdParty.jar
- core_file.txt mh_sh_highlight_all('java');
[Code] ....
Now I want to give two separate versions to client.
Command line version to run as service in Windows andUI version to deploy in their server.
With above structure I create the cmdline.jar but when I am trying to run with
Java Code: java -jar cmdline.jar mh_sh_highlight_all('java');
I am getting java.lang.NoClassDefFoundError exception for the service classes in core. So my question is how to pack/generate jar for this kind of distribution?
Whenever I use a control inside an .fxml file like:
<Label></Label>, <TableView></TableView>, etcera ...
I get an exception for example:
Label is not a valid type., TableView is not a valid Type., etcera
This exception I then solve with placing an import tag inside the .fxml file.
However as I do not know each import name, I have to look this up like writing down:
Label label = new Label();
inside a class and then place my cursor on it to see which import name Eclipse generates.
This import name i then put inside the .fxml file with <? import ?> beginning and end tags with question marks around it.
Is there anyways to automatically generate these import tags inside an .fxml file even if you don't know the import name for the control you want to use?
I want to pass the current timestamp as a key-value pair in JSON and want to store that timestamp in my DynamoDB table. Any sample code in JAVA to perform this operation.

View Replies View RelatedI am currently concentrating on Java programming skills. Right now developing a Energy usecase in Java with Spring framework. Have business requirement to generate data along with outliers. For example, have two parameters called as min and max (centigrates). Generate a file between min and max and store in a file. Atleast need to generate 10 outliers in each 100 records. Outliers should be < min and > max. How to write a java class with this business condition. The file should be like,
Java Code:
Public class DataGeneration(int min, int max)
where min = 30
max = 50
UNIX_TIME_STAMP< >DEGREES
98938409384389384< >30

90853948093849383< >100 mh_sh_highlight_all('java');
From above sample data file, it will be generating two outliers. How to create such kind of data generation in Java class?

Instruction: You work for a telemarketing company and you are required to write a JAVA program that will generate a random phone number. (talk about a real-world application)
-The phone number should consist of 10 digits
-The first 3 are the area code and should not begin with 0, 8 or 9
-The second 3 digits should not be greater than 742 and not less than 100.
-The last 4 digits can be any digits
-Print the number using the following format: "(xxx)-xxx-xxxx", this way it will look like a real phone number (use decimal formatting)

I am trying to generate this request with my Java program, but I just can't seem to figure it out: curl -v -H "Authorization:Basic MY_AUTH_CODE" -H "Accept:application/xml" -H "app_id:MY_APP_ID" -H "app_key:MY_APP_KEY" -X GET "THIRD_PARTY_URL"
I tried to generate a query string, but I keep getting 403 errors. I also tried to input my parameters using URLConnection.getRequestProperty("name", "value"), but that didn't work either.
I have a string of variable tags (tag) filled with variables, and using a Scanner (scan) to manipulate and generate data dictionary add cards for each. The variables are delimited with new line character, and the variables are structured such that the actual name of the variable contains info as to its data type, size, etc. What I need to do is move the scanner to a particular point into the string then use .nextInt() or similar. I don't want to do this to the whole variable, just where I start it from. How can I do this?
E.g..
/* variables in String tag...
ANS_s20Tx12VDstr
ANS_:Tx67MSvis
ANS_zRx11MSctr
...
..
*/
Scanner scan = new Scanner( tag );
int ptr = tag.indexOf( "_" );
ptr++;
if ( Character.toLowerCase( tag.charAt( ptr ) ) == 's' )
// then start at the "_" character and grab the nextInt()
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 program in UNIX directory /home/me/java/src
package bin;
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
I have manage to compile it successfully(class file will be in bin directory) using command below: javac -d /home/t_bmf/java/bin HelloWorld.java
My problem now is how would I execute the class in bin directory in UNIX? I already tried different ways on how to execute it as suggested in my internet research The one I tried is this:
java $CLASSPATH:.:bin/HelloWorld
but I got this error message:
Exception in thread "main" java.lang.NoClassDefFoundError: :/:bin/HelloWorld
Caused by: java.lang.ClassNotFoundException: :.:bin.HelloWorld

I am a student, who are doing a software project. The last step will be deploying the software as desktop exe for both windows and unix.
Question1 : my project has a folder structure like this:
+ Input file folder
+ configuration file folder
+ Output file folder
+ my project codes
So my class in project codes should have proper access to the other three folders(input,output,config). Then what can I do to feed the function a relative path?How would that looks like?
Question2:
Is that true, for windows and unix I have to write two versions of codes on system-dependant path?
