Today, most people don’t need to know how a computer works. Most people can simply turn on a computer or a mobile phone and point at some little graphical object on the display, click a button or swipe a finger or two, and the computer does something. An example would be to get weather information from the net and display it. How to interact with a computer program is all the average person needs to know. But, since you are going to learn how to write computer programs, you need to know a little bit about how a computer works.
Creating a computer program can be like composing music, like designing a house, like creating lots of stuff. Almost all of the computer programming these days is done with high-level programming languages. Java is the high-level programming language developed by Sun Microsystems.
Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web. The Core Java Technology is the foundation of Java
Platform of JSE. It is utilized in all classes of Java programming, from desktop to Java Enterprise Edition.
