Java Lab 004

Instructions:

1. Fork this repository to your GitHub account.
2. Clone the forked repository locally to your machine.
3. Create a new branch named Feature01.

Part 1: Redesigning Code as Methods

Objective: Redesign code from a previous exercise into methods that take parameters.

Instructions:

1. Create a new Java file named RedesignDate.java
2. Write a method called printAmerican that takes the day, date, month, and year as parameters and displays them in American format.
3. Test your method by invoking it from main and passing appropriate arguments. The output should look something like this (except the date might be different): "Monday, July 22, 2019".
4. Once you have debugged printAmerican, write another method called printEuropean that displays the date in European format.

Part 2: Execution Flow and Method Calls

Objective: Review the flow of execution through the program Zippo.java, a program with multiple methods.

Questions to Answer In This README.md:

1. Write the number 1 next to the first line of code in this program that will execute.
2. Write the number 2 next to the second line of code, and so on until the end of the program.
3. What is the value of the parameter blimp when baffle gets invoked?
4. What is the output of this program?

Part 3: Stack Diagram and Program Output

Objective: Answer questions about stack diagrams and program output without running the program in Zoop.java.

Questions:

1. Draw a stack diagram that shows the state of the program the first time ping is invoked.
   • Hint: If you Google how to use IntelliJ's BreakPoint functionality, you can screenshot the program state instead of drawing it.
   • Regardless of your methodology, a picture of the programs state should be added to this Repo and committed.
2. What is the output by the following program?
   • Paste your output in the bash code-block below.

Part 4: Exploring Method Invocations

Objective: Explore method invocations and their consequences.

Questions to answer in the README.md via Markdown:

1. What happens if you invoke a value method and don’t do anything with the result; that is, if you don’t assign it to a variable or use it as part of a larger expression?
2. What happens if you use a void method as part of an expression? For example, try System.out.println("boo!") + 7;.

Part 5: Stack Diagram and Program Output

Objective: Draw a stack diagram that shows the state of the program the second time zoop is invoked in file Part5.java. Determine the complete output.

Questions:

1. Draw a stack diagram that shows the state of the program the second time zoop is invoked.
   • Hint: If you Google how to use IntelliJ's BreakPoint functionality, you can screenshot the program state instead of drawing it.
   • Regardless of your methodology, a picture of the programs state should be added to this Repo and committed.
2. What is the complete output?
   • Paste your output in the bash code-block below.

Submission

Follow these steps for submission:

1. Create a Feature01 branch of your code if you haven't already.
2. Draw the stack diagram and determine the complete output.
3. Commit your answers to your local copy/Feature01 branch.
4. Push it to your Remote/origin branch (i.e., GitHub: Feature01 -> origin/Feature01).
5. Issue a Pull request to my instructor repo.
6. Make sure to COPY the Pull request URL and submit it for the lab/assignment in Canvas.
