What is inheritance in Java?OptionsThe ability to create new classes from existing classesThe ability to create multiple instances of a classThe ability of a class to inherit fields and methods from its subclassThe ability of a subclass to inherit the fields and methods of its superclass

The correct answer is "The ability of a subclass to inherit the fields and methods of its superclass".

Inheritance in Java is a mechanism where a new class is derived from an existing class. In Java, classes are used to create objects (a particular data structure), and methods are used to perform actions. The new class, known as the subclass, inherits the fields (variables) and methods of the superclass. This mechanism is used for code reuse and also for polymorphism.
