title: Load java properties inside static initializer block
body: <p>I have a static util class that does some string manipulation on a bit sensitive data.
  Prior to use of this class I need to initialize certain static variables with values, such as usernames/password, that I prefer to store in a <code>.properties</code> file.</p>
  
  <p>I am not very familiar with how loading of <code>.properties</code> file work in Java, especially outside of *Spring DI *container.
  Anyone can give me a hand/insight on how this can be done?</p>
  
  <p>Thank you!</p>
  
  <p><em>Addition:</em> <code>.properties</code> file precise location is unknown, but it will be on the classpath. Sorta like <code>classpath:/my/folder/name/myproperties.propeties</code></p>
