Causes of memory leaks in Java:

• Improper management of objects in the heap: objects remain accessible through references even when they are no longer needed, preventing the garbage collector from removing them.
• Incorrect use of static variables: static references live for the entire duration of the application, and if they refer to large objects, memory is not freed.
• Excessive use of recursive functions can lead to stack overflow, but not directly to memory leaks.

Types of memory leaks in Java:

• Through unclosed resources: for example, unclosed streams, database connections, which lead to memory retention.
• Using incorrect data structures: for example, collections that continuously grow and are not cleared.

What is Docker? Docker is a platform for creating, delivering, and running applications in isolated containers. Containers allow packaging an application with all its dependencies, ensuring consistent operation across different environments.
