you need to create your public class and then just click on the green button with the white triangle on it ;) See here: https://i.sstatic.net/5TEtI.png

There is no problem with learning Java with Eclipse or any other IDE. If you move file from one computer to the other you need as it was said start a new project or you can use existing project and import files. In order to import files right click on a project and click then Import and select files. Then you should be able to run your class. Also be sure to have the Java perspective selected when you work on your class.

if you are just starting learning Java and dont understand whats going on with all that stuff with eclipse, I would recommend you to start from the basics, write your code in an ordinary text editor (notepad will do, or notepad++ if you want something more), after you have written and saved your source file, open up your command prompt, navigate to the location of the file, and run:

javac YourFileName.java
java YourFileName
