Java is a programming language used for web content, stand-alone programs, and server-side applications. It was developed by Sun Microsystems in the 1990s and is popular for its automatic memory management. Java has five key goals and is often used with extensions. Learning Java is essential for the computer programming industry.
In the computer industry, Java® is an essential skill. Java® is a programming language used to create interactive content for web pages, as well as to develop stand-alone programs and server-side applications. It is often used in conjunction with extensions such as OSGi or CORBA.
Java® was developed by Sun Microsystems in the early 1990s. It started as a project called “Oak” led by James Gosling. Its original purpose was to develop applets, small programs that run in your web browser. However, it was later discovered that Java® was also suitable for building e-commerce applications.
In 1998, the Java® Community Process was established to allow interested professionals to be involved in the future development of this unique programming language. Today, Sun Microsystems provides a GNU General Public License for its Java® virtual machine and compiler. Unfortunately, the library needed to run Java® programs is not yet available as free software.
Java® has five key goals: to improve ease of use by combining the best features of other popular programming languages, to use object-oriented programming methodology to promote greater flexibility in software applications, to contain built-in support for using computer networks, provide a way to run code from a remote source, and allow the same program to run on multiple operating systems.
Java® is very popular because its automatic memory management model allows programmers to avoid the time-consuming task of manually managing memory by implementing a process known as automatic garbage collection. However, some people find that Java® is slower and consumes significantly more memory than C++ or other natively compiled languages. Regardless, a thorough understanding of Java® is required for anyone wanting to work in the computer programming industry.
Learning Java® can be compared to learning the grammar rules for a foreign language, but once you’ve developed a good understanding of Java® you should find it relatively easy to master other common programming languages. There are many different resources available for mastering the basics of Java®. If you are patient and persistent, you can teach yourself Java® using the free tutorials and online courses available on the web. There are also Java® programming classes available at most local community colleges.
Java® is sometimes confused with JavaScript®, a scripting language that shares a similar sounding name but is completely unrelated. Most of the syntax used in Java® comes from C and C++, but the object model is simpler and there are fewer low-level structures to learn.
