Java is a general-purpose, high-level programming language developed by Sun Microsystems. who initiated the language in 1991.
Java is a widely-used programming language. It is also among the most favored for the development of edge devices and the internet of things.
It can also be used to build a small application module or applet for use as part of a webpage.Java can be used to create complete applications that may run on a single computer or be distributed among servers and clients in a network.
Java source code is compiled into Java byte code, which can run anywhere in a network, on a server or on a client environment that we are called Java virtual machine (JVM).
The JVM interprets convert to byte code into code that will run on computer hardware. In contrast, most programming languages, such as COBOL or C++, will compile code into a binary file. Binary files are platform-specific. The JVM includes an optional just-in-time (JIT) a compiler that dynamically compiles byte code into executable code. In many cases, the dynamic JIT compilation is faster than the virtual machine interpretation.
Object-oriented Concept
An object is made up of data as fields or attributes and code as procedures or methods. An object can be a part of a class of objects to inherit code common to the class. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.
Exception Handling in Java
To make a robust and well-behaved application, Java offers an exception handling mechanism using to maintain the normal execution control flow when an exception occurs. The Java exception-handling mechanism contains five keywords: try, catch, throw, throws, and finally.
Interpreted language
Java byte code is translated on the fly to native machine instruction & it’s not stored anywhere. The development process is more rapid and analytical since linking is an incremental and light-weight process.
Data Security
Unlike C++, Java does not use pointers concept, which can be unsecured. but in java environment Data converted to byte code, this code is not possible to read by humans. Secure coding is the practice of developing computer software in a way that guards against the accidental introduction of security vulnerabilities. Defects, bugs, and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities.
Desktop GUI applications
A java GUI application uses the standard java components GUI set, swing & is deployed to the desktop. Java Swing is a lightweight graphical user interface that means a GUI toolkit that includes a rich set of widgets. It includes packages that let you make GUI components for your java applications & it is platform-independent.
Scientific Applications
Java supports scientific application development, because of it is security very powerful, robustness features, much scientific application based on java technology.
Web Applications These are the main component of java which helps to develop the web-based applications. We can develop can kind of web-based application which helps with these technologies.
Mobile Applications
In Today’s world, every second phone has an android OS which is based on Java. Java is the technology of choice for building applications using managed code that can execute on mobile devices.
