FileName$1.class

Question

My file name is FileName.
Why I have FileName.class, FileName$1, FileName$2, etc in my folder?
A compilation feature?

Answer 1

This should be your anonymous inner classes.

Answer 2

@Tashi
It must be if I override methods as follows
className cn = new className(){
@Override void Say(){
System.out.print("Khm.");
}
};
I cant find any classes in my base class.

btw, how to delete a file that has too long title? My experiments led me to inability to delete a file. It says that the title is too long to move into the trash bin. I cannot edit it anyhow on the same reason.
