Set to tell the script to build the BlueJ jar. The Powershell script has several parameters you may specify: Parameter

You can download Maven itself here if you haven't already and are just running it through your IDE.ĭownload BlueJ.ps1 and place it in the root of your project. Refer to Windows prerequisites for instructions. If you haven't already, make sure Maven is in your PATH, verify this by running mvn. You will use the same technique cartoonists have used for a hundred years now: redrawing an image in a slightly different location and repeating that process many times a second so the image appears to move.Note: You may already have the maven-jar-plugin plugin installed, simply replace it or add the extra configuration as above to make it executable. In your final lesson, you will continue exploring Java 2-D graphics with a look at some simple animation. You will also learn about the basic components of a Java window and then add some simple graphics to it. This lesson will introduce you to the world of Java windows, and you will look at GUI (graphical user interface) programming in Java. So far in this course, everything has been text-based.

The interface has several thousand classes, and it's important to know how to find things within it.Ĭreating Windows and Adding Graphics in Java

That's the documentation of all the classes that Java includes when you install the JDK, plus explanations of how to use them. How can you make numbers and other output look the way you want them to in Java? This lesson looks at Java's application program interface (API). You will find all these items useful in future programming!įormatting Output and the Java Application Program Interface

Finally, Java's switch structure lets you replace a series of nested if statements with a single value-based structure. Enumeration lets you set up new data types with built-in limits on their values. BlueJ's debugger lets you watch your program's internal actions as it runs. This lesson is a grab bag of tools and topics. Three Tools: Debugger, Enumeration, and Switch Last, you will find out about a debugger, which lets you look at what's going on inside the program as it runs. You will learn about class methods and how to call them without creating any objects. This lesson focuses on how Java generates exceptions and how to prevent them from crashing your programs. But in a loop structure, if the condition is met, the branch is backward instead of forward. Loops in Java involve decisions, just as branches do. In this lesson, you will learn to repeat actions using a control structure called a loop. When you're done with this lesson, you will know how to write Java programs that make decisions based on the principles of computer logic. This lesson explores the decision-making process in detail and see how Java does it. Without decision-making, computers would be big, bulky calculators. Making decisions is one of the most important and powerful things a computer language can do. Then you will write a program that incorporates all these features.Ĭomputer Logic: Writing Programs That Make Decisions You will learn about data input, which means getting information into programs from an outside source. This lesson covers how to declare data variables in Java and how to use variables in arithmetic expressions.
While doing that, you will look at how to declare classes, objects, attributes, and methods to Java.Ĭreating a Program That Makes Calculations You will revisit the HelloWorld application and rewrite it in Java's OOP (object-oriented programming) structure. This lesson introduces classes and objects. Beyond that, you will explore how to use these classes in the Java libraries. First, you will learn how to use them in some simple programs and how they relate to each other. This lesson is about Java's primitive data types-the building blocks you need to use before you can build more complex types. You will use the editor to enter your program, and you will find out more about how to compile it and run it. Along the way, you will learn to create projects and classes in BlueJ.

Now that you have the software downloaded and installed, you're ready to start programming! It's time to write your first Java program. Then, you will explore the process of editing, compiling, and running computer programs written in Java. First, you will be set up with the downloads and installations you will need for the rest of the course. This lesson will introduce you to computer programming in general and to Java in particular.
Java is one of the most widely used programming languages in the world, on machines from microprocessors in DVRs and microwaves to supercomputers.
