Q1. What is metaspace?
Ans. 
Metaspace is a memory space in Java that stores metadata about classes and methods.
• Metaspace replaces the permanent generation (PermGen) in Java 8 and later versions.

• It is used to store class metadata, such as class names, method names, field names, annotations, etc.

• Metaspace is dynamically allocated and resized by the JVM as needed.

• It helps prevent OutOfMemoryError caused by PermGen space exhaustion.
