advanced java interview questions:

1. *explain the java memory model (jmm)*

the java memory model defines how threads interact through memory and what behaviors are allowed in concurrent programming. it specifies how and when changes made by one thread become visible to others.

*key points:*
*volatile keyword:* it ensures that the value of a variable is always read from the main memory and not from the thread's local cache.
*synchronization:* it is used to control access to shared resources.

*example:*


2. *what are java annotations? give examples.*

annotations in java provide metadata about the program. they do not change the action of the code but can be used by the compiler or runtime for various purposes.

*example:*


*custom annotation example:*

the `==` operator compares references (memory addresses) while `equals()` compares the actual content of the objects.

*example:*


4. *what is the java stream api? provide an example.*

the java stream api, introduced in java 8, allows for functional-style operations on streams of elements. it enables processing sequences of elements (like collections) in a declarative way.

*example:*


5. *what is the difference between `string`, `stringbuilder`, and `stringbuffer`?*

*string:* immutable, meaning once created, it cannot be changed.
*stringbuilder:* mutable, not synchronized, suitable for single-threaded scenarios.
*stringbuffer:* mutable and synchronized, suitable for multi-threaded scenarios.

*example:*


6. *what is the purpose of the `final`, `finally`, and `finalize` keywords in java?* ...
