How do I get a platform-dependent new line charact

Question

How do I get a platform-dependent newline in Java? I can’t use "\n" everywhere.

Answer 1

This is also possible: String.format("%n").

Or String.format("%n").intern() to save some bytes.

Answer 2

If you are writing to a file, using a BufferedWriter instance, use the newLine() method of that instance. It provides a platform-independent way to write the new line in a file.

Answer 3

Avoid appending strings using String + String etc, use StringBuilder instead.

String separator = System.getProperty( "line.separator" );
StringBuilder lines = new StringBuilder( line1 );
lines.append( separator );
lines.append( line2 );
lines.append( separator );
String result = lines.toString( );

Answer 4

The commons-lang library has a constant field available called SystemUtils.LINE_SEPARATOR

Answer 5

You can use

System.getProperty("line.separator");

to get the line separator

Answer 6

Java 7 now has a System.lineSeparator() method.
