Java Heap vs Stack
Question 1
Which of the following is stored in Stack Memory in Java?
- A
Local variables and method calls
- B
Objects and their properties
- C
Class-level static variables
- D
Only Objects
Question 2
In Java, what is true about Heap Memory?
- A
Heap Memory stores method calls and references to variables
- B
Heap Memory is where instance objects are created and stored
- C
Heap Memory is automatically deallocated when methods return
- D
Heap Memory is used for storing thread-related information
Question 3
What happens when a method is invoked in Java?
- A
The method’s local variables are stored in Heap Memory
- B
The method’s local variables and references are stored in Stack Memory
- C
The method’s local variables and references are stored in Method Area
- D
The method execution is not related to memory allocation
Question 4
Where are local primitive variables stored in Java?
- A
They are stored in Stack Memory
- B
They are stored in Heap Memory
- C
They are stored in the Method Area
- D
They are stored in Permanent Generation
Question 5
When an object is created in Java, where is it stored?
- A
Stack Memory
- B
Method Area
- C
Heap Memory
- D
Native Memory
Question 6
Which of the following statements about Stack Memory in Java is true?
- A
It is used for allocating objects
- B
It is shared by all threads
- C
It stores data that can be accessed across threads
- D
It is cleared automatically when a method execution ends
Question 7
Which of the following is NOT true about Heap Memory in Java?
- A
Objects stored in Heap Memory are accessible across different methods
- B
Heap Memory is automatically garbage collected when objects are no longer referenced
- C
Memory in Heap is limited and needs to be manually managed
- D
Objects stored in Heap Memory are shared among threads
Question 8
In terms of performance, which of the following is true about Stack Memory?
- A
It is faster because it follows LIFO (Last-In-First-Out) order
- B
It is slower than Heap Memory because of object creation
- C
It can handle large objects efficiently
- D
It has more memory space compared to Heap Memory
Question 9
How does memory allocation differ between Heap and Stack?
- A
Heap Memory is allocated for storing variables, and Stack Memory is used for methods
- B
Stack Memory is for variables and method calls, while Heap Memory is for objects
- C
Stack Memory stores objects, and Heap Memory stores primitive types
- D
Heap Memory is faster, while Stack Memory is slower
Question 10
Which of the following is a characteristic of Heap Memory?
- A
It is allocated and deallocated automatically
- B
It stores references to variables and method calls
- C
It has a limited size that can lead to StackOverflowErrors
- D
It is cleared immediately after method execution
