What is Java ?

The “Green Team” at Sun Microsystems and James Gosling created Java, a general-purpose, class-based, object-oriented programming language, in 1991. Java’s key features include cross-platform compatibility, stability, and efficiency. One of the most widely used and well-known programming languages in the world is Java.

Java programming can be used for Financial services apps for Android, web apps for servers, big data apps for science, embedded systems for social media, high-frequency trading spaces for software, etc.

Pros and Cons of Java

Speaking of advantages, the following is a list of Java’s advantages:

PROS

Java is a Secure Language:

Because pointers can result in unapproved memory access, this is a potential threat. Java likewise utilized OOPs concepts such as summarization, abstraction, and inheritance to increase security and prevent unauthorized user access.

Java is Inexpensive and Simple to Maintain

Because of its simple design, Java is inexpensive and simple to maintain and develop. Java can operate on any technology, regardless of the system’s hardware, which significantly reduces development costs.

Java is platform-independent:

JavaScript programs written in one system can be operated  on any other computer that has java. Java compatibility is not dependent on the operating system or hardware, making it platform-independent and extremely flexible.

Java provides portability:

Java is a highly flexible language. This is due to the fact that Java is platform-independent and doesn’t require any special devices to run. As a result, Java is simply compatible with most every device.

Java is reliable:

Java is updated on a regular basis to fix bugs. As a result, Java is among the most sustainable programming languages available in the market. So most bugs are immediately removed via updates. Hence it is critical to keep Java up to date.

Cons of Java

Despite the fact that the highly esteemed language has a long list of advantages and the added benefit of longevity, it has a few cons too:

• It performs less than optimally because it is slower than native languages like C or C++ and uses CPU time for automatic memory management.
• Java programs consume more memory because they run on top of the Java Virtual Machine.
• As memory and processing necessities grow, hardware costs rise.
• It focuses on storage rather than having any backup capabilities.

Node.js vs Java: What are the Main Differences?

Performance

Java uses compilers, which makes it slower than native languages. Contrarily, Node.js-based applications never buffer, allowing for faster runtime and chunked data output. And although Just-In-Time compilers might slightly boost Java’s performance, node.js comes out on top in terms of speed and performance.

 Stability

Java and Node.js are total opposites with each other in terms of stability. Node.js is designed to be used in conjunction with APIs. Since APIs frequently change, apps created in this environment frequently experience stability problems. Java is renowned for its extremely stable interfaces because of its strict, tried-and-true structure.

Scalability

Although the lack of internal scalability in Java can be remedied by integrating third-party programs like NCache, it does not currently have any (for distributed cache). Node.js’ event system enables servers to give a response in a non-blocking manner, which makes them highly scalable. Scalability is one of Node’s key characteristics.

Cost of Development

Java development is cheaper in the US and Indian market. If you want to outsource your development or hire freelancers, you will encounter prices that vary largely.

Typically, it is difficult to pinpoint the exact cost because project complexity, strategic planning, drawbacks, as well as other factors all influence the estimates. But compared to Java, Nodejs has high cost of development .

Security

Security is one of the most important things to consider while choosing the technology for web development. Node.js lacks in error handling or application failure. That is why it’s not too secure . In contrast, Java is extremely secure. There are no security problems other than those that might be caused by certain integrations.
