System.lineSeparator() vs line.separator property

System.lineSeparator() vs line.separator property

Java 7 introduced System.lineSeparator() as a more convenient and readable way to get the system's platform-dependent line separator string.

How it Works

Internally, it still queries the 'line.separator' property but wraps it in a method call. This avoids the need for System.getProperty("line.separator") and makes the code cleaner.

Java Example

public class LineSeparatorExample {
    public static void main(String[] args) {
        String separator = System.lineSeparator();
        System.out.print("Line 1" + separator + "Line 2");
    }
}

Output

Line 1
Line 2

Key Points

• Platform-independent newlines
• Cleaner alternative to getProperty()
• Standardized in Java 7
• Ensures correct file formatting across OSs
