Error: Selection does not contain a main type

by

Right click on the folder where you put your main class then click on Build Path –> Use as Source Folder.

Finally run your main file as java application. Hope this problem will be solved.

If the option ‘Use as Source Folder’ is not visible then inside the ‘Build Path’ select the option ‘Remove from Build Path’. This will allow ‘Use as Source Folder’ option to appear in the ‘Build Path’.
