Java MCQ: Which class is used to obtain information about a class in Java Reflection?

Answer:

Explanation:

The Class class in Java is the primary class used to obtain information about a class in Java Reflection. The Class class is part of the java.lang package and provides various methods to inspect the structure and behavior of classes at runtime.

To obtain a Class object, you can use one of the following approaches:

• Using the .class syntax: Class<?> clazz = MyClass.class;
• Using the getClass() method: Class<?> clazz = obj.getClass();
• Using the Class.forName() method: Class<?> clazz = Class.forName("com.example.MyClass");

Once you have a Class object, you can use it to retrieve information about the class, such as its fields, methods, constructors, and annotations. The Class class provides methods like getDeclaredFields(), getDeclaredMethods(), and getDeclaredConstructors() to inspect different components of the class.

The Class class is fundamental to Java Reflection, as it allows you to perform a wide range of operations on classes at runtime, making it a key component of dynamic and flexible Java applications.
