How to write/convert below Kotlin code to Java. I have implemented a Kotlin library which is completely written in Kotlin
The library uses this code as callback. I need help on how I can call it from Java class.
timelinePicker.setOnSelectedTimeRangeChangedListener { from, to ->
selectedTimeTextView.text = getString(R.string.from_to, from.format(), to.format())
}
timelinePicker.setOnSelectedTimeRangeChangedListener((from, to) -> {
selectedTimeTextView.setText(getString(R.string.from_to, from.format(), to.format()));
});

The example here: https://github.com/mapstruct/mapstruct-examples/blob/3457f37c24ea7799b0752cc7ee8307283ab09ad2/mapstruct-mapping-with-cycles/src/main/java/org/mapstruct/example/mapper/EmployeeMapper.java
The generated mapping will be like:
Employee toEmployee(EmployeeDto employeeDto, CycleAvoidingMappingContext context) {...}
In practice, how to get a valid CycleAvoidingMappingContext object ?
You use the constructor.
new CycleAvoidingMappingContext()
When in doubt, look for unit tests.

I have this code in Python:
if word[x:x+2] in twowords:
(twowords is a list). I can't figure out how to write in twowords in Java.
It looks like Python uses [x:y] to create a substring. You can use the substring method for that purpose, with the same parameters.
There is no in syntax in Java, but all Lists in Java support the contains method.
Try
if (twowords.contains(word.substring(x, x+2)))

getJSON("sample.json") is not working when invoking from html in D:" { "name" : "blah" } getJSON("D:/data/sample_json.json",fun
You won't be able to request JSON by using a path to a file on your system. Its hard to say if this is the only thing you'll need to change though.

So I got this bit of code http://pastebin.com/RMh4eHLq from the Android dev blog (modified) but when I try and call it via
ImageDownloader.download(image, image_main, image_table);
it tells me to change the download modifer to static but if I do that the ImageDownloader class tells me no portion is accessible. Any ideas?
Have you tried with:
ImageDownloader imgDwn = new ImageDownloader();
imgDwn.download(image, image_main, image_table);
