Java is a commonly used and also high-level object-oriented programming language that has a wide application verity and allows programmers to develop applications for web, mobile, and desktop. Below are the principles, features and characteristics of programming in Java:- Java is simple: It is a very simple language as it is easy to learn and create using the best features of other languages, mainly C and C++. When an individual has the basics of the concept of object-oriented programming, it is easy to learn Java. Java also provides automatic memory management based on the development environment and eliminates pointers which gives the programmer an error-free development environment. - Java is platform independent: Java provides the ability for cross-platform programs by collecting intermediate code known as "bytecode" that can only be read on any system equipped with a Java Virtual Machine (JVM). Additionally, Java offers the option of “Write Once – Run Anywhere” or known as platform independent. There is no single language that is inactive to this feature, but Java is still closest to these features. - Java is object oriented: Java is a completely object oriented language because the object is located at the outermost level of the data structure in Java. It also supports OOP features. Every single thing in Java is preserved as objects to which procedures are applied. The entire object in Java is an object, including primitive data types which can also be converted into objects via wrapper class. - Java is distributed: program developers can call functions on protocols such as HTTP and FTP. They can access files from any remote machine on the Internet instead of writing codes on the local system. - Java is safe...... middle of paper ...... offers no help in making the program reliable and less likely to crash. The best example is the Ada language, which was designed from the beginning to make the program more reliable. It is usually used for safety-critical systems. - Development and maintenance costs Considering the cost to develop a project or maintain it could be important for undertaking software development. Few languages ​​have a reputation for reducing cost and time to make program development and maintenance quick and easy. - Expandability Different software programs must support thousands of concurrent users. There are systems written for interactive websites that needed to support huge numbers of users without crashes. But some other languages ​​scale or expand compared to others. These features typically support large systems that are considered a strong choice for a project.
