I started doing some exercises of a book I’m following in Java, everything was fine, until yesterday I was compiling and running the good programs. Then today DO NADA stopped running the programs to give this error there, and I can not solve in any way!
It’s not misspelling, it’s not lack of package in the execution (nor package I’m putting for these exercises, are simple as Hello World), it’s not lack of compilation. There is simply the file . class but when I call it says it could not find!
Nor does Hello World spin!!!
