“Java Memory Management MCQs” is an article that offers a collection of multiple-choice questions (MCQs) focused on Java’s memory management. These MCQs are designed to help Java developers improve their understanding of memory handling, garbage collection, and best practices. Whether you want to assess your knowledge, enhance your skills, or prepare for interviews, these questions provide a practical and engaging way to boost your expertise in this crucial aspect of Java programming.
1.) What is the primary purpose of the Java memory management system?
2.) In Java, where are local variables and method call stack frames stored?
3.) Which memory area is responsible for storing class metadata, constants, and method information?
4.) What is the primary purpose of the Java Garbage Collector?
5.) Which part of the memory is dedicated to storing object instances and arrays?
6.) How does the Java Garbage Collector determine whether an object is eligible for garbage collection?
7.) Which garbage collection algorithm is known for minimizing pause times but may require more memory?
8.) What happens when an object becomes unreachable in Java?
9.) Which type of memory leak occurs when an application keeps creating objects without releasing them?
10.) Which memory area stores objects that have class-level scope, such as static variables?
