I try snap7 project and i find very useful functions. but in java version of snap7 (moka library) some methods is missing.
for example, now, I want to get list of all data block (DB). in c, there is a method (Cli_ListBlocksOfTyp) but I don't know how to do it in moka.
anybody can help me?
The reason is, that not all functions are ported in moka. As you can see in the MOKA overview.
The overview also contains all functions providet by MOKA.
Hope it was helpfull.

Ive looked everywhere for a solution to read RPM data on Android Auto with Android studio. Found no solution. I was hoping someone has more experience in this field and could point me in the right direction.
I tried to use CarHardwareManager and looked into CarPropertyManager but I cannot find any proper documentation on how to implement an RPM listener of some sort.
My end goal is to have a listener that will receive the current RPM the vehicle is at.
Please help! Thank you!
There is this function that you can use to get properties.
CarPropertyManager.getProperty()
You need to use constants defined in VehiclePropertyIds. Here goes the one that could do the trick:
VehiclePropertyIds.ENGINE_RPM. Note that this requires certains permissions.
Also the function seems to take a areaId argument. It's a little confusing but using CarPropertyManager.getAreaId(ENGINE_RPM, VEHICLE_AREA_TYPE_WHEEL) may yield the required value. Please double-check it as I cannot test it myself.
CarPropertyManager.getProperty(propertyId, areaId). This should return a CarPropertyValue. Then you can use getValue().
As for the listener, you may implemented this interface to listen for changes in such properties.
CarPropertyManager.CarPropertyEventCallback
CarPropertyManager.registerCallback(callback, propertyId, refreshRate)
I'll link to registerCallback documentation https://developer.android.com/reference/android/car/hardware/property/CarPropertyManager#registerCallback(android.car.hardware.property.CarPropertyManager.CarPropertyEventCallback,%20int,%20float)
I made a fast google search about this topic but I can't find any relevant result. So, does anyone knows at least one example of a realworld webpage that uses JadaSite as its webshop implementation? Thank you in advance.

I want an API in java which would give me the meaning of words. I tried using JWKTL but I am not getting it. Could anyone direct me regarding this. Thank you.
Have you checked WordNet?
But if you're interested in Wiktionary, you may consider checking JWKTL alternative: Wikokit
Is there any open source Java implementation for LDPC (Low Density Parity Check) codes, I found only MATLAB codes.
My scenario is I will take text file and divide into block and I will delete some data in text file, and by using LDPC codes I need to recover data from text files.
Thanks.
I haven't tried this but the code here should get you started

It's in C though. Might be easy to port. Or not.
I'd suggest looking into ways of calling matlab functions in java. I know there are a couple. Also why LDPC? While its one of the best FEC, it involves lots of matrix manipulation if I recall correctly. This is stuff much better suited for mat[rix]lab. The right tool for the right job...
There are also these two pure Java implementations:
https://github.com/a4a881d4/ldpc-java
https://github.com/pierroweb/LDPC-correcting-codes
I haven't tested them and would appreciate feedback from anyone else that has.
There's also a Java wrapper around a C++ library: http://cpham.perso.univ-pau.fr/MULTICAST/Java_wrapper_for_LDPC.html
Not the most promising results, but something to start from, at the very least.
I'm looking for a Java solution to this. I need a Java method that behave exactly the same as php IMAGEJPEG method does.
Thanks in advance.
Here is a really good tutorial on saving images in Java http://download.oracle.com/javase/tutorial/2d/images/examples/.
The specific class you want to look at is ImageIO http://download.oracle.com/javase/1.4.2/docs/api/javax/imageio/ImageIO.html
