java - Backspace \b Chacacter Scope with regard to OS? -

i looked extensively, unable find information regarding scope of \b character in java.

note: using eclipse, , know provides limited no support character. (side question if want answer: looking console eclipse plugin supporting \b char)

i want know 2 things:

can write backspace char file delete written test? (i don't need this, reduces compatibility if can't program)

can delete newline (\r\n or either) character \b?

can write backspace char file delete written test?

no.

can delete newline ("\r\n" or either) character \b.

no.

the situations characters \b interpreted when writing screen, console or terminal.

characters written file not treated this.

this not java-specific restriction. rather inherent in way operating systems¹ handle writing data files.
