Hi,

I am reading as below from link

According to the JavaSW Language Specification, whitespace in Java consists of the ASCII space character (SP), the ASCII horizontal tab character (HT), the ASCII formfeed character (FF), and line terminators.

Line terminators consist of the ASCII newline character (LF), the ASCII carriage return character (CR), and the ASCII carriage return character followed by the ASCII newline character.

All these ASCII codes are an heritage from the time of the Teletype machine, but they are still being used on our printers and screen with almost the same effect.

LF - Line Feed
CR - carrier return
FF - Form Feed
HT - Horizontal Tab

All these codes are invisible, they just produce an action to position the next character to be printed.
Only the ASCII SP (space) code produced by the space bar on the keyboard is visible, otherwise we would see  allthewordsmixedtogheter.

\r - 0x0D - CR - Carraige return
Move to the leading end (left) of the current line.

\n - 0x0A - LF - Line Feed
Move to next line.

\f - 0x0C - FF - Form feed
Form feed means advance downward to the next "page". It was commonly used as page separators, but now it is also used as section separators. (It's uncommonly used in source code to divide logically independent functions or groups of functions.) Text editors can use this character when you "insert a page break".
