Java: How to get the name of the current thread

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:

Thread.currentThread.getName();

When you’re writing a simple, single-thread program the current thread shows up as “main.” In some RxJava code I worked with recently another thread showed up with the name “RxCachedThreadScheduler-1.”

In summary, if you need to get the name of the current thread in Java, Scala, or other JVM languages, I hope that’s helpful.
