Question 2

When you pass a(n) ____________________, you pass a memory address.

Accepted Answer

reference

Question 3

What does it mean when a variable overrides another variable? Describe the process of declaring variables in methods and memory locations.

Accepted Answer

While you cannot declare a variable twice in the same block, you can declare variables in a method of a class and use that same variable name within other methods of the class. The variable that is declared inside each method takes its own computer memory locations. Therefore, when you use the variable's name in the method where it is declared, it will override other variables with the same name in another method. A locally declared variable will hide another variable with the same name elsewhere in the class.
