If you want to automatically generate getters and setters for your Java JavaBean classes, Project Lombok has some annotations that you can use.

When you’re working with multi-threaded programming in Java — such as when working with Thread, Runnable, SwingUtilities.invokeLater, Akka, futures, or Observable in RxJava — you may need to get the name of the current thread as a way to debug your code. Here’s how you get the name of the current thread in Java:
If you ever need to convert a Java array into a Stream, there are at least two ways to do it.
1) Converting an array to a Stream
First, to convert the entire array to a
Stream, use the
Stream.of static method like this:
The first thing you do is create a new Gradle/Java project with these commands:
mkdir MyProject cd MyProject gradle init --type java-application
With that project created you can begin creating some Java/RxJava code.
As a bit of warning, this is some old Java code, but if you want to create your own Java file utilities (utility methods), this code might help you get started:
I ended up not using this code, but if you wanted to see one way to use JSoup’s OutputSettings (Document.OutputSettings) class to set some parameters before calling
JSoup.clean, I hope this is helpful:
// tried some things to improve the html output val settings: OutputSettings = new OutputSettings settings.prettyPrint(true) //`true` is default settings.charset("UTF-8") settings.outline(true) //this is close to what i want, but too extreme settings.indentAmount(4) val cleanHtml: String = Jsoup.clean(html, "", wl, settings)
I can attest that this code works, it’s just not what I need at the moment.
Also, the code shown is written in Scala, but as you can see, it converts easily to Java.
Java FAQ: How large can a Java

“BigInteger must support values in the range -2Integer.MAX_VALUE (exclusive) to +2Integer.MAX_VALUE (exclusive) and may support values outside of that range.”
BigInt wraps Java’s
BigInteger, so it will also have the same data range.
I haven’t read the article I’ve linked to yet, I’m just saving it here for future reading.
In this InfoQ Java in 2019 Predictions article, this line stood out the most: Java 9 and 10 saw virtually no deployment to production. Working alone I occasionally wonder what large companies are doing, and with these Java major version number releases coming every six months I was wondering how that was playing out.
