Ok so I just started to learn java right, got eclipse and all, I set up the environment variable but after writing the basic hello world I try to run it and get this message "the selection cannot be launched, and there are no recent launches" I really take this serious as this is what I want to do with my life, I have no teacher and learn everything I can from the internet which is kinda slow but I do my best, this message is becoming frustrating as I cannot move forward please help, anybody
P.s I already tried deleting the environment variable I put in and redoing it, like 4 times already, plus typing javac on cmd gives me that bunch of messages so I think the fault is not from the path. Thanks in advance

Hello,

how are you trying to launch your program?
Do you have a main method?

Did you try to follow one of these great tutorials http://www.vogella.com/tutorials/Eclipse/article.html#create-your-first-java-program ?

Hi Stanley,

The Run button is related to the current selection in your workbench.
So please ensure that the java main class or the project which contains the Java main class is selected before clicking on Run.
Please also ensure that your project is recognized as a Java project, you should have a little J decorator on the project icon.
