Solution
The keyword used to define a generic class in Java is b. generic.
In Java, generic programming allows developers to define classes, interfaces, and methods with type parameters. This means you can create a class that can operate on objects of various types while providing compile-time type safety. The syntax for defining a generic class includes the use of angular brackets <> after the class name, where you specify the type parameter(s).
For example:
class Box<T> {
private T item;
public void setItem(T item) {
this.item = item;
}
public T getItem() {
return item;
}
}
In this example, T is the type parameter that can be replaced with any object type when you create an instance of Box. This allows for more flexible and reusable code, as the same class can work with different data types without casting and type-checking at runtime, ensuring type safety at compile time.
