Java Lessons and More

Looking at how to use arrays to hold a collection of integers. Exploring how to access and change values.

Do While Loop reminded me of doo-wop. I heard recently from someone that music and programming are connected fields. Continuing our discussion of loops in this episode with for loops. Note that all loop types can be nested.

In this episode, we dive into how to read text files into your software application and how to program the processing of each line, separating out the contents by delimiters. Please note that the file must be in the same directory as your Java development environment.

Introduction to the use of while loops to keep things going if a condition is met or to stop repeating if it’s not!

Like having a remote control, you give your users the power to easily choose between a variety of options by implementing a switch statement in your Java class bodies of code.

We wrap up our exposé of if statements for now with touching on how to fit more content in between the logic statements with the proper use of curly braces, and also how to fit if statements inside of if statements using the concept of nesting.

Adding on an else statement to last week’s code. These help to account for other scenarios or options not covered by just a plain if statement. Like what if you order a grilled cheese but the restaurant is out of Texas Toast, what other options are there?

We explore how to use if statements and the logic behind how they operate (in as simple terms as I can and with practical examples to make it easier).

As planned, we are taking a break to do a fun mathematical magic trick. Try it out with your friends or family. Mathemagic!

In this episode, we discuss how to use enumerated types in Java. We look at two different ways to access the name and how to use it to determine the ordinality of the elements. I believe this lesson is the last of the not-so-exciting numerical Java stuffs, so hopefully next week we can do something fun like a magic trick.
