Java: how to line break in a properties file?

In a Java properties file, you can include line breaks (newlines) by using the escape sequence \n. Here's how to do it:

  1. Open or create your .properties file using a text editor.

  2. To insert a newline in a property value, use the \n escape sequence. For example:

    welcome.message=Hello,\nWelcome to our application!

    In the above example, the property welcome.message has a newline character \n embedded in it. When you read this property in your Java code using Properties, the newline character will be interpreted as a line break.

  3. In your Java code, use the Properties class from the java.util package to load and read the properties file. Here's an example of how to do it:

    import java.io.FileInputStream; import java.io.IOException; import java.util.Properties; public class PropertiesExample { public static void main(String[] args) { Properties properties = new Properties(); try (FileInputStream input = new FileInputStream("your.properties")) { properties.load(input); } catch (IOException e) { e.printStackTrace(); } String welcomeMessage = properties.getProperty("welcome.message"); System.out.println(welcomeMessage); } }

    When you run this code and read the welcome.message property, it will interpret the \n escape sequence as a line break, and you will see the output with a line break:

    Hello, Welcome to our application!

Remember to adjust the code and property file paths according to your specific use case.
