SSK3100 (Group 15)

Morning world!
Today I will explain about what I have learned in SSK3100 course. This is the first lecture and what I learned.
Firstly, download Java via website and install the program in computer.

Next, go to Control Panel - System - Advanced Setting - Environment Variables - System variable - search for ''Path" and edit the variable value by entering the java jdk 10.0.2 bin link into the column.

So now, open the Command Prompt.

FYI : ''mkdir'' stands for create a new folder
         ''cd'' stands for enter the file you created

Create a SSK3100 folder followed by kyee and lab01.

Next, save a notepad in your lab01 file.
Copy the script from attachment that lecturer gave into the notepad and Save as "MyFirstJavaProgram".

''java - version'' - to check on your java version

''set class'' & "set classpath" - This is a exceptional step when you found out your java program is not functioning well. so this step is needed.

When you see ''Hello World'', you are DONE!


But anyway there is some typing error in command. Not to worry, just retype the command and it will goes well.

Practice makes PERFECT!
