Since it was launched, Java has been the topic of conversation. Java’s predecessor C++ (which is also an object-oriented programming language) was not without its flaws. Java is a perfect substitute for C++. Its longevity is astounding due to the fact that modern technologies are replacing the older ones at a rapid pace over the course of over twenty years after it’s invention, Java is still the most widely used language for applications software development. In the present, Java is one of the most popular programming languages. It’s so robust that it can be used to do nearly everything from basic applications as web-based servers. This means that it Java programming language a feasible choice for all kinds of developers regardless of what kind of work they choose to perform.

Characteristics of Java
Java is a simple language
Do not get me wrong! Java isn’t a walk in the park but its syntax is easy and easy to grasp. It draws many of it’s syntaxes and syntax in C as well as C++ programming languages, so if have one or both of them, Java will be easy for you to master. Java has eliminated many of the more complicated and infrequently used functions like operator overloading, pointers, and so on. Additionally, an automatic garbage collector eliminates unneeded objects and memory-consuming instances without the need to do it manually.
Object-Oriented
Java is an object-oriented language. The term “object-oriented programming” (OOP) is an approach to programming that structure the design of software around data instead of logic and functions. An object is a field that has distinct properties and behaviour. For instance, a school class could have variables such as Name Class, Name Roll Number Father’s Name, Marks and methods to store and retrieve these data values.
The concept of object-oriented programming (OOP) is focused on the objects that programmers would like to manipulate and not the logic required to manipulate the objects. This type of programming is ideal to large, complex and often updated as well as maintained applications. This includes design and manufacturing software and mobile apps such as OOP could be utilized to simulate manufacturing systems. The primary notions of OOPs include:
- Object
- Class
- Inheritance
- Polymorphism
- Abstraction
- Encapsulation
Platform Independent
Java code is compatible with various platforms, including Windows, Linux, macOS and many more. Compiler is able to compile Java software and transforms it into the byte code. Because it can operate on different systems, this byte code is platform-independent, i.e. Write Once, Run Anywhere (WORA).
Secure
Java is utilized in a networked and distributed environment. The following attributes make Java an extremely secure language
- There is no need to use explicit pointers
- Java Program runs inside a virtual Sandbox (Java Virtual Machine, also known as JVM).
- Classloader classloader Java Runtime Environment (JRE) has a classloader utilized to dynamically load Java classes to Java Virtual Machine. Java Virtual Machine. It enhances security by separating the application for local classes in the file system from those that are imported from networks sources.
- Byte code verifier
- Security Manager decides the resources that a class has access to, for example, writing and reading on the local disk.
Robust
The word “robust” means strong. In the context of a dictionary for programmers it is a reference to reliable. There isn’t a programming language that is able to guarantee 100% reliability. Because Java compilers can detect many defects that could be discovered when executing various languages Java place a large importance on early error detection. Certain kinds of programming errors that are common in other languages have been eliminated from Java. Java does not provide, for instance, pointers, which reduces the chance of writing memory over and damaging data. To support programming to ensure the resilience of data, Java has a runtime system for handling exceptions. Java makes the programmer write code to handle exceptions. Java can recognize and respond to unexpected situations which allows the program to run normally, and gracefully end whenever a runtime error occurs.
Architectural Neutral
Because there are no implementation-dependent aspects in Java, such as the size of primitive types, it is architecture-neutral. In C programming it is the data type called int that occupies two bytes when it is in 32-bit architecture, and four bytes for 64-bit architecture. In Java however, it consumes four bytes in both 64-bit and 32-bit architectures. This gives the developer freedom to the developer to use cutting or byte overflow.
Portable
Java programs are portable because they are architecture-independent. They don’t require modified to run on every platform. Java software can be transformed into byte codethat can be carried easily.
Performance
The efficiency and performance of Java are impressive considering that the byte code is very similar in comparison to computer code. However, it’s slower than other languages like C++ which are constructed. The main reason is Java applications, in contrast to C or C++ applications are run by the Java virtual machine (JVM) after compilation, instead of directly running to the CPU of a computer using native codes.
The performance of the performance of a Java written bytecode Java software is determined by the way host Java virtual machine (JVM) handles its tasks and how effectively the JVM makes use of the software and hardware (OS) when doing so. For the majority of interactive applications that use the CPU, which is often idle, and waiting on input or input from different sources, the speed of the JVM is greater than.
Distributed
Distributed computing involves the cooperation of several computers via the internet. Java was designed to make distributed computing as simple as possible. Because networking is built into Java creating network-based applications is as easy to send and receive data and from the file. Java also comes with a wealth of features to create microservices (is an architectural model that allows an application to be designed as a collection of smaller applications) within distributed system.
Multithreaded
Multi-threading is an Java feature that allows the execution of more than one part of a program simultaneously to increase the efficiency of CPUs. A thread is an element of such a software. Threads are thus light-weight procedures within processes. For instance, when surfing the internet, one is able to listen or play an audio track. A server could serve many clients simultaneously when it comes to the network programming. In the same way, there are numerous activities happening in GUI programming simultaneously. The simultaneous process are possible to implement in Java by using multi-threading.
