Project Structure

ApplianceManager.java

Executes the main code of the program.

• Initializes a custom set of appliances using the CustomSet class.
• Adds predefined appliance objects (WashingMachine, Refrigerator, Microwave) to the set.
• Demonstrates adding a new appliance (Fan) and displays the contents of the set.
• Handles exceptions that might occur during execution.

Appliance.java

Defines the abstract base class Appliance, representing a generic household appliance.

• Fields:
  • name: The name of the appliance.
  • power: Power consumption in watts.
  • isPluggedIn: Boolean indicating if the appliance is plugged in.
  • electromagneticRadiation: Radiation level in microteslas.
• Methods:
  • Getters for all fields.
  • plugIn and unplug methods to simulate the appliance being connected or disconnected from power.
  • toString: Formats the output information about the appliance in a readable format. WashingMachine.java, Refrigerator.java, Microwave.java Concrete subclasses of Appliance that represent specific types of appliances.
• Each class initializes an appliance with predefined values for name, power, and electromagnetic radiation. CustomSet.java Implements a generic collection class, CustomSet, which adheres to the Set interface.
• Features:
  • Internal structure: Uses an array with an initial capacity of 15, dynamically increasing capacity by 30% when full.
  • Constructors:
    • Default constructor initializes an empty set.
    • Constructor accepting a single object adds it to the set.
    • Constructor accepting a collection adds all elements to the set.
  • Implements all Set interface methods, including:
    • add: Adds an element if it does not already exist.
    • remove: Removes an element if present.
    • contains: Checks if an element exists in the set.
    • iterator: Provides an iterator over the set elements.
  • Ensures capacity dynamically grows as needed.
