The short answer, as you might have noticed, is that they are very different languages, despite the similarity in name.
Because JAVA is compiled ahead of time, it is often much easier for IDEs (and other developers) to see exactly how your code was intended to operate before it’s in use.
Also, certain types of performance enhancements can be made as a result of compiled languages that are not typically inherent in scripted languages.
That being said, Brendan Eich was a genius in implementing a few core concepts. First, he made functions as variables.
Third, as a scripting language for the web, it was very open (everyone could see it), really helping the open-source community thrive on the web.
To give an example.
When I’m writing JAVA code, I’m frequently required to write lots of boilerplate code just to get something running.
I’m constantly telling JAVA things I feel it should already know since I already told it those things about 5 other times in 5 other places.
There are lots of restrictions on how I’m able to do things. But — and this is pretty big when you’re working with other developers — it’s usually much more clear what I’m doing. There’s much more safety built into the language.
Indeed, I can easily write code that writes code that does what I want.
This really helps with things like keeping code DRY (Don’t Repeat Yourself), but all sorts of confusion can result if you don’t practice discipline — which many coders don’t do in rushed environments, which is how many environments are.
The composition is much better and more intuitive in most cases.
Sometimes they add their own flavor of how to do things which seems as different as trying to combine.
So, in short,
There is no other language I can think of that is so important to use test-first development for.
This is one area where an ounce of prevention is worth 10+ lbs of cure, so just do it.
Java is an object-oriented language designed and has always been a full-stack language used in a variety of applications such as Desktop, Web, Enterprise, Embedded, Mobile and Batch applications. Java has inspired quite a lot of languages such as Groovy, Scala, Clojure, Kotlin and has its influence on JRuby and Jython. Android has its syntax similar to Java.

James Gosling is Inventor of Java, popularly known as the father of Java.
Java is a full feature Object-oriented programming language, used in almost everywhere, starting from programming credit card to server-side coding.
Android uses Java as a programming language for creating Android apps, Swing is a Java API used to create desktop applications and Java EE is a Java platform for developing web and enterprise applications.
1) Execution Environment
2) Static vs Dynamic Typed language
Though it also provides === operator to perform a strict equality check, which checks for type as well.
3) Support of Closures
Java doesn’t treat the method as the first-class citizen and the only way to simulate closure is by using anonymous class.
By the way, Java 8 has brought real closure support in Java in the form of lambda expression and this has made things much easier.
It’s very easy to write expressive code without much clutter in Java 8.
Java provides packages to group related class together, provides much better deployment control using the JAR, WAR, and EAR as well.
5) Right Once Run Anywhere
7) Block vs Function-based Scoping
Java mainly uses block-based scoping i.e. a variable goes out of scope as soon as control comes out of the block unless it’s not an instance or class variable.
There was some hope that they’d be used together and evolve together.
They never really were; Java applets never took off.
The two languages have some surface similarities. They’re both procedural object-oriented languages, so they look more like each other (and like C++ and C#) than they look like, say, Prolog, Lisp, or Haskell.
Experience in one prepares you for the other no more than any other common programming language, like C or Pascal.
As I said, they are totally different languages, one is a general-purpose programming language, while the other is a scripting language for HTML.
