Interfaces

• Can only contain abstract methods.
  • However, since Java 8, default and static methods are also allowed.
• Can include public static final constants.
• Supports multiple implementations.
  • A single class can implement multiple interfaces.
• Provides looser coupling compared to inheritance and offers a standardized way of use.

public class MyClass implements InterfaceA, InterfaceB, InterfaceC {
    // ...
}

Interface Fields

Fields in a Java interface are implicitly public static final by default.

default Methods

• Methods in an interface that contain implementation code.
• Provide a default implementation that all implementing classes can use.
• Can be overridden in the implementing class if needed.
• Enable adding new methods to an interface without breaking existing code.
