Answer 1

Maybe, you are running the 'project' instead of just the class BasicSorting_1. Then this error may apear because you have the "main method" in both classes (BasicSorting and BasicSorting_1), then Java can't determine wich class he will use as 'main'.

Try running just the single java file;

If that's not working, try checking out the package(if you really have it):

package Sorting;
