A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

visio 2013 standard does not show the "UML Sequence" template as shown below
https://www.youtube.com/watch?v=_xtZIDI8Ajg
only professional viso 2013 shows it?
are there existing sample diagrams which i can use as sample and modify on top of them easily?
any alternate tool to draw these type of diagrams easily apart from visio like free open source tools?

Scenario:
A particular business card design can only accommodate up to three phone numbers.

Assume the phone numbers are always formatted as 10 digits with dashes. For example:
   Mobile: 456-789-1234
   Office: 987-654-3210
   Fax: 345-678-9012

There are only 2 lines to accommodate 3 phone numbers.

If (and only if) all 3 phone numbers contain a value, then the mobile and office numbers must appear on the first line, and the fax must appear on the second line, like this:
Mobile: 456-789-1234    Office: 987-654-3210
Fax: 345-678-9012

If (and only if) one of the 3 phone numbers does not contain a value, then the remaining 2 numbers must appear on their own line, like this:
Mobile: 456-789-1234
Fax: 345-678-9012

The example above assumes the Office number is the empty field. But if the Mobile number was the empty field then it would look like this:
Office: 987-654-3210
Fax: 345-678-9012

And if the Fax number was the empty field, then it would look like this:
Mobile: 456-789-1234
Office: 987-654-3210

If 2 of the 3 numbers are empty, then return just the one remaining number.

So given all of the possible phone number combinations, we have:
M   O   F
M   O
M       F
M
    O   F
    O
        F

HI,
Is there any website where one can post there understanding of computer science concepts or explain them and then user can ask questions. Although expert exchange also has article section.
But i want to specifically do it for Java concepts Java 8 features etc.
The idea is to feel motivated to study it... as it helps learning the material in a quicker way
Any alternative suggestions
Thanks

Which is the best out of the three -

Activiti
Camunda
Flowable

Is all of them support CRUD operation with default search options or filter options for any table or entity defined ?
if anyone of them has it by default, please let me know.
Does anyone knows the differences and pros and cons of the above?
Is there is any other open source is better than the above for java app?

Hi,

I am working on an iOS application (in nativescript) that needs to get and post some data to an API in the background each 5 minutes. Now it seems that iOS is closing my application so I took a look at the long running tasks section of https://docs.nativescript.org/core-concepts/ios-runtime/how-to/BackgroundExecution but I fail to see how I should configure an interval now.

Also while it works correctly on the simulator (not thinking about the interval) with the debug fetch command, I can't get it to work correctly on a real device.

Hi Experts,

there are two approached to pass sheet names vaue
1st approach:

JRXlsExporter exporter = new JRXlsExporter(); exporter.setParameter( JRXlsAbstractExporterParameter.SHEET_NAMES, new String[] {"first","second","third"} ); 

Open in new window


cant we pass this value as parameter in java?

this way(1st approach) i am unable to follow because i am sheduling report for a specificdate. and passing few parameter inputs as well for the same report.

sample:
Util.getParamString(stringBuilder, "GENERATEDON", Date);//similarly few more params i am passing

Open in new window


2nd approach:

iam setting in the report properties like below(2nd approach): Property Name = "net.sf.jasperreports.export.xls.sheet.names.all"

 Property Value = "first/second/third"

is there any chance to pass this property value as dynamic.?

I have tried like below as not works for me

<line> 
<reportElement x="0" y="-1" width="1" height="1"> 
<propertyExpression name="net.sf.jasperreports.export.xls.sheet.name"><![CDATA[$F{course_name}]]></propertyExpression> 
</reportElement> 
</line>

Hi all
We have a number of Android tablets, some of which are misbehaving. I need to be able to save (or send) the system logs (and maybe dmesg as well, if poss) continuously to the removeable SD card, or alternately, to send the logs out to an FTP server. Can someone help me do this please? I will not be able to "root" the devices.
Thanks in advance

Hi all,

I have problem to display my PDF file in an existing popup window using spring framework. The workflow is when I click a button from the main page, it popups a new window (child) and showing progress status. After the file finished generating, I set the view in controller and return to jsp. However, the PDF file displays (using DefaultResourceLoader and response.flushBuffer) in the main page instead of the popup window. I want to show in popup. Anything wrong? How can I specify which window the PDF should be displayed?

Please help. Thanks.

I would like to change the names of the members of the list. The list is of a CPI hierarchy - the trouble is the names are now ID numbers, that are difficult to interpret. Each one of the members has a readable tag, that is "CPI.Tag".

How would I swap the label that is used for the name  currently to the "CPI.Tag"? (the display of a few sample members is attached)
2018-08-14_13-32-00.png

I thought it would be something along the lines of names(jpCPIlist)<-jpCPIlist$CPI.Tag, but evidently not..

Generic Form, Controller, Service and Search fields for Java Web Application

I want to built an application where there will be 500 screens which needs basic CRUD operation and individual field search or combined search field option is required.

Everything when we build entity in Java/JPA we want to have separate controller, service, repository and search api.

Is any framework or open source it has all in common, where we can use the generic controller, service, repository and search and export options by default instead of writing any new code snippet

However we can extend whenever is required.

Please advise.

Can I replicate a search using the Google Maps API local search with  an iOS MKLocalSearchRequest() ?  For example, using the Google API, making a map search using the keyword "hostels" works correctly. In iOS using MKLocalSearchRequest(), using a naturalLanguageQuery, I just get hotels. Is there a way to fix this?  Or am i forced to use the Google Maps API within iOS?
