Print in new line, java

Question

I have following code :

    System.out.println(" | 1  2  3  4  5  6  7  8  9");
    System.out.println("----------------------------");
    System.out.println("");

I use println to create a new line. Is it possible to do the same using \n or \r? I tried to add \n to the second println statment and continue printing with the print method but \n does not create a new line.

any ideas?

I wonder why you have problems to simply write `System.out.println("\n)";` The "\n" considers as escape sequence for C/C++/C# and Java aswell. — Malakai, Oct 16 '16 at 11:56

    String newLine = System.getProperty("line.separator");//This will retrieve line separator dependent on OS.

    System.out.println("line 1" + newLine + "line2");

Since Java 7 you have `System.lineSeparator()` http://docs.oracle.com/javase/7/docs/api/java/lang/System.html#lineSeparator%28%29 – Marc-Andre Nov 22 '13 at 20:08

is `System.out.println();` looked down upon? Doesn't this do the same thing? This is my second day in Java, came to find best practices. – Dan Aug 14 '14 at 00:03
it does except that it adds line separator at the end – jmj Aug 14 '14 at 00:07
Great! This is really useful for me. – Nyein Mon Soe Jul 22 '15 at 07:47

Your best shot would be with

String.format("%n")

or

System.out.printf("%n");

It is supposed to print a newline character, depending on the current platform, so it's perfect for the console.

If you are printing to a file, then it depends.

This is far by the best answer since it address the problems discussed: 1. Platform and 2. Java Versions. – tortal Feb 19 '21 at 23:38

You should use the built in line separator. The advantage is that you don't have to concern what system you code is running on, it will just work.

Since Java 1.7

System.lineSeparator()

Pre Java 1.7

System.getProperty("line.separator")

It does create a new line. Try:

System.out.println("---\n###");

In the past, the Apple Mac requirse lines to be separated by '\r', So its better to write system independent code , check my solution – jmj Oct 24 '10 at 12:46
He's talking about "new line". Had he requested "new line + carriage return" I'd pointed him to \r\n :) If we're going to be picky, then I'd suggest using a StringBuilder rather than concatenating strings. – biasedbit Oct 24 '10 at 12:54

For `"line 1" + newLine + "line2"` using a StringBuilder explicitly would be counter-productive. The compiler can optimize this by itself. – Thilo Oct 24 '10 at 12:58

You might try adding \r\n instead of just \n. Depending on your operating system and how you are viewing the output, it might matter.

\n creates a new line in Java. Don't use spaces before or after \n.

Example: printing It creates\na new line outputs

It creates
a new line.

where does it say that using \n in java will use the correct newline, such as \r\n on Windows? – simpleuser Nov 11 '16 at 23:31

Since you are on Windows, instead of \n use \r\n (carriage return + line feed).

number will be printed in one line like 1 2 3 4 5 for new line we can use \n – Gajendra kumar Mar 06 '17 at 13:11
Does not answer the question. Even worse - attempts to solve a problem unrelated making it only confusing. Moreover - there is no explanation at all! – tortal Feb 19 '21 at 23:44
