We will also show you how to load a properties file from the classpath and how to read all the keys from the properties file. Java Properties File Example.
The PROPERTIES files that are created by the many different software applications contain a list of variable names and value pairs that pertain to the associated computer application. This data stores the properties of the associated application. If a user changes the properties of the software, the PROPERTIES file is then updated as the.
Each parameter in properties file are stored as a pair of strings, in key and value format, where each key is on one line. You can easily read properties from some file using object of type Properties. Below is a example program which demonstrate to read the data from .properties file using Java.
