Java is a general purpose programming language. That is, a language that is used in the development of various software products, without a clear specialization in a particular area. It is similar in many ways to Python, JavaScript, and other languages at the same level as Java. In addition, Java borrows a lot of syntax from C and C++.
It is an object-oriented language. The whole structure is built around objects, classes, instances and other formal entities accepted in the programming community as the OOP development standard. It's like designing houses using separate building blocks, which can then be used to build different types of buildings. Programs written in Java are made up of similar "blocks", which reduces development time and makes the code more readable and easier to modify.
Java also acts as a platform. Code written in this language runs in the JVM virtual machine and is initialized without problems in any system where the corresponding virtual machine is supported.
History of Java
The Java language was developed by a team of Sun Microsystems engineers in 1995. The company, along with Java, was later taken over by Oracle Corporation.
A key goal in the development of Java was to create a programming language that could run on more than just computers. That is, it was versatile enough to work even on the operating system of the refrigerator. At the time of development, such a decision seemed too far-sighted, but it brought with it several important architectural changes that became critical for Java and made this language popular.
For example, the language allowed you to write code once and compile it without changes for any third-party software. This greatly simplified development and, more importantly, reduced the number of man-hours required to write code.
