3.4 Line Terminators

Implementations next divide the sequence of Unicode input characters into lines by recognizing line terminators. This definition of lines determines the line numbers produced by a Java compiler or other system component. It also specifies the termination of the // form of a comment (§3.7).

   the ASCII LF character, also known as "newline"
   the ASCII CR character, also known as "return"
   the ASCII CR character followed by the ASCII LF character

   but not CR or LF

Lines are terminated by the ASCII characters CR , or LF , or CR LF . The two characters CR immediately followed by LF are counted as one line terminator, not two.

The result is a sequence of line terminators and input characters, which are the terminal symbols for the third step in the tokenization process.
