I might go against the grain here, but if I've had nothing but pure bliss working in Java.
If you're just starting out, Head First Java is the way to go. Then expand your knowledge, look at things like Lombok, or go for one of the languages built on the JVM (Kotlin/Scala). Want insane performance out of the box? Look at Vert.X. There's a library for everything as the language has been around since '95.
