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.
