How to read properties file and fetch data? Write code to read common.properties file?

• In below code filepath parameter will contain the path where we will keep the properties file and key parameter is the name of the value which we want fetch.
• public is the access modifier
• static  so that we can access the class without creating object
• String is the return type of propertyReader function

============================
public static String propertyReader(String filePath,String key)

{
        String value = null;
       
        //Inputstream is required while loading into properties
   
       try (InputStream input = new FileInputStream(filePath))
        {
           
           // object creation for Property class
            Properties prop = new Properties();

            // load a properties file
            prop.load(input);

            //getProperty will fetch the value according to the key
            value=prop.getProperty(key);
         

        } catch (IOException ex) {
            ex.printStackTrace();
        }
        return value;
       
    }
