What are interfaces in Java?
Interfaces in Java are abstract classes that have no instance variables, no constructors, and are composed only of methods, constants, and default methods. They provide a common set of methods that can be implemented by any class that implements the interface. Interfaces allow for a level of abstraction and create a contract between two or more objects.

What is a thread in Java?
In Java, a thread is a concurrent process that allows multiple independent tasks to run simultaneously. A thread has its own call stack, program counter, and local variables. Threads may share memory and other resources, making them potentially more efficient than multiple processes. Threads can be used to process tasks in the background, allowing the main program to run without interruption.

What is JVM pooling in Java forms?
JVM pooling in Java forms is a process in which a single instance of a Java subprocess is created and used by multiple web applications, instead of having a different JVM instance for each application. The pool is managed by a Pool Manager, which creates and manages the runtime environment for each individual application in the pool. This reduces memory usage, and improves scalability and performance as more applications are added to the pool.
