As promised, here is the second magic trick I’ve been talking about (credit to Jim Steinmeyer). Also, for now, unless there are further questions or requests, I am closing the podcast. I appreciate all the kindness and support from all over. Thank you!!!! 😊
In this episode, we round out the Java portion of this podcast (for now). I appreciate all of your support!
In this episode, we introduce try-catch statements to help give you options for when your program encounters an error (so that it doesn’t just break!). Also, I make a correction to my improper formatting that I spoke about before.
We take a look at the difference between binary and linear searches, when to use them, and the advantages and disadvantages of each.
First podcast-only episode! We talk about selection and insertion sorts and how to use them in your programs.
In this lesson, we talk about ArrayLists, a highly flexible way to handle collections of objects. We also wrap up our unit on arrays!
In this episode, we dive into tables! (Or vectors/arrays in the second dimension!!!) and how to write and read these in Java.
A brief explanation of how to have lists containing a certain type of object but which can be of variable length
You know the String[] args thing? Yeah, we talk about what that is all about.
(NOTE: See Twitter for the screen capture) In this episode, we introduce object-oriented class, object, and method programming. We talk about arrays of objects and also how to access characters using the Scanner object.
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.
In this episode, we tackle how to format the precision of decimals down to the exact, precise number of decimal places or digits after the decimal point.
In this lesson, we learn how to print out money and percents formatted properly using Java.
We go to the Math Class in Java and learn how to use the various operators to perform desired calculations.
In this episode, we explore how to generate random integers and decimals using the Random class in Java.
Learn how to manipulate strings in various ways. Also, we touch a little on Applets and graphics in this lesson.
Expanding on last week’s lesson, we take a look at how to interact with users in new ways. Scanner objects can be used to read in more than just text strings! Listen in to find out more!
Learn how to create a software program utilizing the Scanner object. In Java, Scanner allows the user to input text and is a good first step in creating interactive programs.
Looking at mathematical expressions in Java that employ integers and doubles. Exploring how these get used and computed.
Describing how to assign a new value to an integer once it has been declared with a given value. Also, I’m learning how to REST, in multiple ways.
How to create and use an integer in a Java program/code.
