Do java packages need a IDE

Question

I tried to create a package but it's giving errors! Sololearn said to make a package with something that does not look possible in the Sololearn console! Is my code wrong or am I coding in the wrong place?

Answer 1

Sololearn is not an IDE.

Answer 2

But does it need an IDE? I know it's not but does package creation need it?

Answer 3

Sololearn is a “web IDE” but it does not support your own Java packages.
You are trying to import a class of the sample package,
inside sample package itself, which is not necessary.
And pou is not public.

you need to have the java development kit installed in your computer. You don't strictly need an ide, a simple text editor will be enough, but an ide will probably give you better tools and workflow management.
