The finalize keyword in Java is used to manually suggest the garbage collector to consider an object for garbage collection.

Cache is not a type of memory area in the Java Virtual Machine (JVM). The primary memory areas in JVM include Heap, Stack, and Registers.

Using StringBuilder instead of concatenation in loops for string manipulation enhances performance in servlets because StringBuilder is more efficient in handling string concatenation operations.

In high-performance servlets, the Flyweight pattern can be used to manage resource-intensive objects efficiently by sharing common parts of state among multiple objects.

For optimal servlet performance, session data should be kept to a minimum, utilizing Session Tracking for state management.

To improve scalability, servlets can delegate database reads to Stateless instances, as they do not maintain client-specific state between method calls.

Optimizing database queries would be a key strategy in this scenario, as it directly addresses the performance issues associated with handling massive data queries.

Implementing load balancing is a key strategy to distribute the incoming traffic among multiple servers, ensuring a better balance and improved performance for a high-traffic web application.

Reducing unnecessary object creation is a good practice to optimize memory usage in a resource-constrained environment, as it helps minimize the overhead associated with object allocation.

The ServletContext is shared across multiple servlets within a web application.
