Cross-Platform Newline Characters in Java

When working with strings in Java, it is often necessary to insert new line characters. However, the operating system you're running Java on may use different newline characters, such as "\r\n" for Windows and "\n" for Linux and macOS.

To overcome this platform dependency, Java 7 introduced the System.lineSeparator() method. This method returns the native newline character sequence appropriate for the current platform. Here's how you can use it:

String newLine = System.lineSeparator();

This variable will contain the appropriate newline character for your platform, whether it's "\r\n" for Windows or "\n" for other operating systems. By using System.lineSeparator(), you can write code that handles newlines consistently across different platforms.
