JAVA Simplified 02 HelloWorld in JAVA with Eclipse under Linux Ubuntu -- Getting Started
In this lesson, you will learn to write a simple program called Hello World. We'll use Eclipse under Linux Ubuntu. To code in JAVA,
you had better install Eclipse, on which you need to create a JAVA project and program file. Program file is also known as source file, source code, source code file, java file and etc.
Tip:
don't be afraid of making mistakes. As long as you are operating on the virtual machine I gave you, do whatever you want. If you mess things up so bad, you can shut down the virtual machine and replace it. This virtual machine is always available for you to download.
Tip for beginners:
Each of you guys have different expectations on what you learn in this lesson and in the subsequent lessons. Firstly, what we will NOT do is: we will not make graphic user interface. We'll not drag and drop buttons, textbox, radiobutton, etc. The programs we will write doesn't always look glamorous. They are mostly background programs that run behind the scene. Secondly, what we do is to process input and obtain the desired output or do a certain task. Input can be manually input data, can be file, can be data queried from database. For instance, you might want to send reminders to each and every students through email; you are reminding them 1 day in advance to go to the class. In addition, different students go to different classes on different days at different times. Sending emails can be a repetitive, tedious, and time consuming manual operation. Or we can let computer do it automatically. So, in this example, the input IS students' information, such as their email addresses, what classes they attend. The task, is to send different emails to the students. In this series, starting from the 4th lesson, we will develop such a program, step by step, piece by piece.
