## How to Load Properties Files in a Hierarchical Java Package Structure?

Finding the Properties File

When dealing with a hierarchical Java package structure, loading properties files can present a challenge. The question revolves around accessing a properties file buried within the com.al.common.email.templates package.

To address this, a solution is provided to load the Properties object from within the specified package:

<code class="java">Properties prop = new Properties();
InputStream in = getClass().getResourceAsStream("foo.properties");
prop.load(in);
in.close();</code>

It's important to surround this code with appropriate exception handling.

Package Awareness

If the class accessing the properties file is not located within the com.al.common.email.templates package, the InputStream must be acquired differently:

<code class="java">InputStream in = 
 getClass().getResourceAsStream("/com/al/common/email/templates/foo.properties");</code>

Relative vs. Absolute Paths

Relative paths in getResource() and getResourceAsStream() search within the directory representing the package the class is in. Absolute paths (beginning with "/") ignore the current package, while relative paths without a leading "/" are relative to the package directory.
