3 cards from this section. Quick, good the night before a test.
What is a stack frame?
Think about what information is needed for method execution.
What does the operand stack do?
Consider how calculations are performed.
What does each stack frame in the Java Stack store?
Consider what information is necessary for method execution.
True or False: The operand stack is used to store local variables permanently.
Think about the lifespan of each type of data stored.
There are three consecutive method calls in a program; each calls another method recursively. What is the maximum stack depth if each method call can have two local variables, and what are the implications if this depth is exceeded?
Consider the recursive structure and how many frames could be created.
Develop a simple Java program that triggers a StackOverflowError and explain how the Java Stack handles each method call.
Focus on how recursion should ideally terminate with a base case.
