Kas saaksid loetleda Properties tüüpi objektide peamised omadused Java's?

The Properties objects in Java represent a specialized class for storing key-value pairs, where both the key and the value are strings. Main features:

• Inherit from Hashtable<Object,Object>, but are typically used with String.
• Commonly used for storing configuration parameters.
• Allow loading and saving data in .properties format via load(InputStream) and store(OutputStream, String) methods.
• Support specifying default values through the constructor.
• Do not guarantee the order of elements.

Usage example:

Properties props = new Properties();
props.setProperty("username", "admin");
props.setProperty("password", "12345");

String user = props.getProperty("username");
