how many characters in \n JAVA?

Question

just a quick question.

I wonder how many characters count for \n (new line ) in JAVA?

Because I need to fit 160 chars in one String,etc.

So.. How many chars should I consider for \n when appending to my StringBuffer?

Thanks

Answer 1

'\n' itself is one character when represented internally in Java, but when interfacing with external systems it can be represented by anywhere between 1 and 8 bytes. Some systems and protocols represent a newline with \r\n , which is 2 characters. And the encoding matters as well, since it can cause each character to use 1, 2, or 4 bytes.

Without more information on what system or protocol the characters are going to be sent on it is not possible to give a completely accurate answer.

Answer 2

1 character.

String str = "qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq\n";
System.out.println(str.length());

output 160

Answer 3

'\n' is just a single character.

Answer 4

\n should be single character only.

Answer 5

The property System.getProperty("line.separator") is a system dependant new-line String. This can be one or two characters. \n is the line feed (single) character which could happen to be the same as a new line, but this is platform dependant.

Answer 6

\n in java corresponds to only one character. If you need to check then might this code will help.

String str = "\n";
char[]  test = str.toCharArray();
System.out.println(test.length);

Answer 7

'\n', '\r', '\t', '\0' they are all one character in both java and c/c++, and other languages.
