Java MCQ: Which of the following best describes Java’s garbage collection mechanism?
Answer:
Explanation:
Java uses an automatic memory management mechanism known as garbage collection. The garbage collector automatically reclaims memory occupied by objects that are no longer reachable or in use by the program. This process helps in preventing memory leaks and reduces the burden on the programmer to manually manage memory allocation and deallocation, which is common in languages like C and C++.
While garbage collection in Java is automatic, developers can optimize memory usage by understanding how the garbage collector works and by writing efficient code that minimizes unnecessary object creation.
Understanding Java’s garbage collection is crucial for managing memory effectively and for optimizing the performance of Java applications.
