 How to print the letter J with dashes in java



Taking the step to print out anything (in this case the letter J) using dashes (or any other single symbol for that manner) is a great baby step in many programming languages.

I've seen wonderful examples of fairly sophisticated art (i.e. simpsons art) created using a single symbol.  The road there includes some of the simplest trial and error.  You can quickly move from creating the letter J to creating another letter, or perhaps your name initials, and then even to complete words.

This is another baby step that is worthy of practicing, by following, and then by aiming to complete more and more without referencing, and then completely by memory, and to practice often.

So let's do it, and discuss it, just a bit ...


Here's the code:

  1 public class PrintJ {

  2     public static void main (String argv[]) {

  3         System.out.println("----------");

  4         System.out.println("    --    ");

  5         System.out.println("    --    ");

  6         System.out.println("    --    ");

  7         System.out.println(" -  --    ");

  8         System.out.println(" -----    ");

  9     }

 10 }

Here's what we used when building this code:

* java 8

* vim editor (note: we have much love for intellij and other editors too!)

* code was placed in a file named PrintJ.java

Here's what we did to run the code:

* javac PrintJ.java

* java PrintJ

Here's what you'll see when you run it:

----------

    --    

    --    

    --    

 -  --    

 -----    

Here's a bit of description about the code and concepts used:

  • the public class name of PrintJ is the same as the filename, and that's important in order for the file class to compile
  • The syntax System.out.println is used for printing lines of content, and the content that you want to be printed belongs between the quotes
  • The typical public static void main function is added and is the entry point to the application
  • The dash character (-) is used to enable content to be printed on each line, working together to form the letter J

Another baby step completed, nice job!

How to create a java app that converts fahrenheit to celsius and allows you to list the cities you want converted in an input text file

     How to create a java app that converts fahrenheit to celsius and allows you to list the cities you want converted in an input text file To create a java app that converts fahrenheit to celsius and allows you to read the input cities (and their default celsius) from an input text file, there are a number of small steps to take. Once you master this app, you could easily reverse the order and convert celsius to fahrenheight, or you could advance to more complex capabilities. This is another baby step that is worthy of practicing, by following, and then by aiming to complete more and more without referencing, and then completely by memory, and to practice often. So let's do it, and discuss it, just a bit ... Here's the code:    1 import java.io.BufferedReader;   2 import java.io.FileReader;   3 import java.io.FileWriter;   4 import java.io.IOException;   5 import java.io.PrintWriter;   6     7 public class FahrenheitToCelsius...

How to create a java app that creates a very simple plot from data in a csv file

   How to create a java app that creates a very simple plot from data in a csv file To create a java app that creates a very simple plot from data in a csv file can be done in several ways.  In this example we'll use simple readily-available technology (specifically leveraging swing, which is an older java technology) instead of using more modern options like javafx and instead of pulling in some of the really cool packages out there now that can be leveraged from maven.  Depending upon comments and interests, we may show how to do the same (or better) using those technologies. Once you master this app, you could easily advance to more complex csv files and more complex aesthetics on the plot.  There are also a variety of plots you could explore. This is another baby step that is worthy of practicing, by following, and then by aiming to complete more and more without referencing, and then completely by memory, and to practice often. So let's do it, and discuss i...

Learn Java: The ABC's of Java

Learn Java: The ABC's of Java Let's get right to it and explore a sample list of ABC's to support our learning of Java. A is for Arrays.  You can create simple one or two dimensional arrays in Java that allow you to keep a simple list of things.  A is also for algorithms, as algorithms (simple step by step processes of how you want your code to work in plain english) are the beginning of a great app.  A is also for abstraction because java code is a gateway into building real world capabilities that are "real enough" to learn and play and solve problems, and the art of coding only what you need to for a purpose is important. B is for Built in capabilities and functions.  This allows you to do so much with pure java, before you worry about any dependencies or even any imports, and these solve many, many problems for you.  Each data structure in java also has built in functions that help you do useful things like check its length.  B is also for bytecode, whi...
