How do structure and class provide inheritance differently in Java?
In Java, classes provide inheritance through a hierarchical structure where a subclass can inherit fields and methods from a superclass, allowing for code reuse and polymorphism. This enables the subclass to extend or override behaviors of the superclass. In contrast, Java does not support inheritance through structures (often used in languages like C), as structures in Java are not a distinct type; instead, classes are the primary way to create complex data types with inheritance capabilities. Consequently, classes are the primary mechanism for implementing inheritance in Java, while structures are not a feature of the language.

Can you compile interface in java?
In Java, you cannot compile an interface directly because interfaces themselves are not executable; they are meant to define a contract for classes that implement them. However, you can compile the interface along with the implementing classes. When you compile a Java program, the Java compiler generates bytecode for all classes and interfaces, which can then be executed by the Java Virtual Machine (JVM).
