One of the most use programming languages used today is known as Java. The inspiration behind the programming language goes back to the languages such as C and C++. The Java developers saw how the C++ programming language tends to get bogged down and may have many bugs within the code. Even more importantly, C++ developers had to we write the same C++ programs again for compatibility with different operating systems. Java developers came together to figure out a way to make a programming language that is portable but yet powerful and robust. In 1991, the company called Sun Microsystems developed the programming language that was called Oak as in an oak tree that stood out the office window, but it was quickly renamed Java before the programming language was officially released. Later, the company called Oracle had now taken ownership of the Java programming language. “Write once run anywhere” is a very popular phrase that the Java developers created. The greatest benefit is that the Java programming language can be compiled once and ran on Windows operating system, UNIX, as well as Mac operating systems without having to rewrite the program for each operating system. They achieved the write once run anywhere ability by using what is called a Java virtual machine or JVM. Having that Java developers created the JVM makes it much easier to have more secure programs created as well as being more bug free than programs that was created with other programming languages. In the early years of computer programming, programs or console-based with only text and numbers. GUI stands for graphical user interface. Program his head created what is called GUI as pronounced as Goo-ee. Java’s GUI library was one of the first of the major software programs in this architecture, which was a library that was filled with methods and event listeners built-in for ease of
