Complete Java SE 8 Developer Bootcamp - Passing By Value: Objects

The video tutorial explains how method invocation works by passing an object reference, creating a new stack frame, and performing operations on the heap. It demonstrates the process using a 'debit fee' method, showing how references are copied and how changes affect the heap. The tutorial also covers string immutability, illustrating how changes to strings create new objects rather than modifying existing ones, using a 'salutation' method as an example.

What happens when the method 'debit fee' is called with an account reference?

Explain how the dot operator is used within the 'debit fee' method.

What is the significance of the stack and heap in the context of method calls?

Describe the behavior of strings in Java when passed to methods, using the 'salutation' method as an example.

What happens to the original string when a new string is created in the 'salutation' method?
