How to Use Properties Files in Java

How to Use Properties Files in Java

In Java, you can easily create and use a properties file containing name/value pairs. First, make a .properties file?name it Properties.properties. Place key/value pairs such as name = java in the file where “name” is the key and “java” is the value. Now, you can use this name attribute/key in your .java code by creating a ResourceBundle like this:

 ResourceBundle rb = ResourceBundle.getBundle("Properties"); String name = rb.getString("name").trim(); 

Note that the second line retrieves the value of the key named “name.” Doing this helps avoid having to hard-code values in your Java files. It’s also easy to maintain and provides better readability.
