[Java] How to Insert Line Breaks in a String

Differences in Line Break Codes

The line break code can vary depending on the operating system.

Examples

Line breaks can be achieved by directly including the line break code in the string.

String text = "Hello \r\nWorld";
System.out.println(text);

Hello
World

Example Absorbing Environmental Dependencies

Java offers a standard feature to obtain environment-independent line break codes.

By using System.getProperty("line.separator") as shown below, you can get the appropriate line break code for the execution environment.

public static final String LINE_SEPARATOR = System.getProperty("line.separator");

String test = "Hello" + LINE_SEPARATOR + "World";
System.out.println(test);

It's recommended to use System.getProperty("line.separator") for line breaks in Java.
