While at first this may look a bit intimidating, once you get the hang of it, using the help of tools like javap, you can quickly begin to intermix Java and Scala. In addition to opening the door for mixing the two languages in enterprise applications, this will greatly help you to use some powerful libraries written in Scala, right from your current Java applications. In the next chapter, you’ll apply what you’ve learned in this book. We’re going to create a small application and along the way pick up a few ...
