1. Strongly and Dynamically Typed
Java locks all variables into a specific type, and if mismatches happen, you are not allowed to execute the code until the issue is fixed. This situation asks for excellent coding habits and requires that intentions are oriented through any project in Java; therefore, a developer can become better and better.
The only disadvantage is that a good amount of ceremony surrounds strong typing, and because new properties and methods are public, they have to be part of the public interface, which means they need to be defined in the inheritance tree.
Still, the disadvantage of dynamic typing is not knowing what the variable contains at any time, and if some wrong content is assigned to a variable, one can not discover it until a nonsensical line is being executed. There are ways to remedy this challenge, but this asks for an overhead that is not an issue when it comes to strongly typed languages.
2. Compiled and Interpreted
Java is a compiled language that checks the code of the whole project while converting scribbles into a byte, which the JVM reads. That’s why it catches a significant number of syntactical errors and tells developers at the compile time.
After that, it operates with a compressed package of bytes like WAR or JAR, and the package can be executed by a virtual machine that can open it, load it in memory, find a point to enter, and bring it to somebody’s server or desktop.
Of course, this concept does not protect from logic errors in programming, but the developer at least has a chance to correct all the syntactical errors exceptionally quickly. Furthermore, Java doesn’t essentially protect the code, but there are tools to protect the output outlined in different resources online.
Still, this makes many various solutions and manipulations of the existing code base; therefore, it requires a great deal of discipline and organization to build and maintain large projects, which can be challenging.
Some packages can help, but none of them will help entirely. This happens because the interpreter has to read the code at the same time as execution.
3. Usage of Both Sides
Nevertheless, the critical element that shows how effective Java is is the companies that use it worldwide. Some of them include the following ones:
- Google – It uses Java in a lot of their apps
- Airbnb – In most cases, for back-end development
- Twitter – In order to gain a smooth digital interface
- Uber – It was actually built on Java
- PayPal – It became the first significant payment platform that used Java
As you can see, these and many more top-rated companies use Java as their preferred choice, which again shows how effective it can be for your business as well.
Nevertheless, it is fair to say that Java is the better choice, especially for beginners, but it can be even more effective when an experienced developer uses it. Therefore, hiring a Java developer who knows the job is the perfect choice for achieving the desired results.
