I have a string of binary. I need to convert this to a wav file. Is there any existing library to achieve that goal? If so how would I write the bytes to an audio file in preferably Java or Python, but any language works.
See the documentation for Wave_write Objects included with Python's standard library. You will need to open a WAV file first in 'wb' (write only) mode, and then use the appropriate methods:
Wave_write.close()
Wave_write.setnchannels(n)
Wave_write.setsampwidth(n)
Wave_write.setframerate(n)
Wave_write.setnframes(n)
Wave_write.setcomptype(type, name)
Wave_write.setparams(tuple)
Wave_write.tell()
Wave_write.writeframesraw(data)
Wave_write.writeframes(data)

I have a service written in python.
This service uses DataFrame from pandas.
The thing is that it (the service) should be translated to Java.
For that I need a similar library in Java. (or is there other way to achieve this?)
I would like to know what are some options for this.
Till now I have joinery library
Besides joinery you could also take a look at tablesaw library. Here is link to a brief tutorial: https://jtablesaw.github.io/tablesaw/gettingstarted

I would like to know the best way to generate reports in java. I have written a small code in java which reads data from my csv file and printing in console. how can i pass this data to my HTML reports.
Thanks in advance
The two options I would consider for creating an HTML representation of your data are Apache Velocity & Freemarker. Both of these are easy to use template engines that separate the generation & formatting of the output from the Java code which I find improves maintainability.

Is there an existing application or library in Java which will allow me to convert a CSV data file to XML file?
The XML tags would be provided through possibly the first row containing column headings.
Maybe this might help: JSefa
You can read CSV file with this tool and serialize it to XML.

I'm developing in swift for iOS and i would like to convert my Utils library in java to swift.
Is there any online converter to convert simple java code into swift code?
I don't know about a java to swift converter, however, Google developed a Java to objective-C converter, you can find it at https://github.com/google/j2objc
You can use objective c files together with swift files in one project. I think this is the only way to go.

Is there some Java library for converting .svg to .png or .jpg at code ? Does anybody have experience with this ?
Check out Batik, which has an Apache license.
Specifically, you should take a look at the Batik Rasterizer.
Here are the associated JavaDocs for manipulating it at the code level:
