How to get started with Java: Introduction to Java IDEs

Go to all tips in Murachs Java SE6 book

Introduction to Java IDEs

Dozens of Integrated Development Environments (IDEs) are available for working with Java. A typical IDE provides not only a text editor, but also tools for compiling, running, and debugging code as well as a tool for building graphical user interfaces. Eclipse and NetBeans are two of the most popular professional IDEs for working with Java. And BlueJ is an IDE that's popular for beginning Java students.

Although you've already learned how to develop Java applications with TextPad, we realize that you may prefer to use an IDE, especially if you have previous experience with one. That's why we developed free tutorials that show how to use this book with popular IDEs like Eclipse, NetBeans, and BlueJ. Each tutorial shows how to download and install a specific IDE, how use it to work with the applications presented in this book, and how to use it to debug an application. To download one of these free tutorials, please visit our web site at:

How to get started with Java: The Eclipse IDE for Java

Go to all tips in Murachs Java SE6 book

The Eclipse IDE for Java

Eclipse is a software framework for developing IDEs. Eclipse is opensource, available for free from www.eclipse.org, runs on all modern operating systems, and includes a popular Java IDE.

The first screen in figure 1-17 shows the window you use to edit Java code using Eclipse. As you work with this code editor, Eclipse can help you complete your code and notify you of potential compile-time errors. In addition, Eclipse will automatically compile your programs when you run them. And when you run a program that prints text to the console, Eclipse displays that text in its own Console window.


The second screen in this figure shows the windows that are displayed when you use Eclipse to debug a Java application. Here, you can use the code editor to set breakpoints, and you can use the buttons in the toolbar to step through your code. As you do, you can use the Variables window to view the values of all of the active variables. If you've used any modern debugging tool, you should understand how this works.

In addition, Eclipse provides many other advanced features that aren't available from a simple tool like TextPad. For example, you can use Eclipse with JUnit, which helps you test your applications, and also with Ant, which helps you document, package, and deploy your applications.

The NetBeans IDE

NetBeans is open-source, available for free from www.netbeans.org, runs on all modern operating systems, and includes a popular GUI builder that can be used to develop GUIs for Java applications.

The first screen in figure 1-18 shows the window you use to edit code using the NetBeans IDE. This code editor provides many of the same features that are available from the code editor that's available from Eclipse. Like Eclipse, NetBeans will automatically compile your programs when you run them. Also, when you run a program that prints text to the console, NetBeans displays that text in its Output window along with some other text for the application.

The second screen in this figure shows the popular GUI builder that's available from NetBeans. This GUI builder is sometimes referred to as the Matisse GUI builder, and many programmers consider it to be the most intuitive and easy-to-use tool for building GUIs for Java applications. To use it, you can drag Swing controls from the Palette window onto a form in Design view. Then, you can use Design view to align the controls, and you can use the Properties window to set the properties for the controls. As you do this, the code that displays the IDE is automatically generated. Finally, you can generate event handlers for the events that you want to handle and use Source view to write the code that handles these events.

Like Eclipse, NetBeans also provides a professional debugger and other advanced features that aren't available from a simple tool like TextPad. For example, NetBeans provides support for the JUnit and Ant tools.
