Generating getters/setters and constructorsĪs with any modern IDE, there are many keybindings to do all sorts of actions in Eclipse. Renaming a variable, field or class, etc.Īlt+Shift+S can be used to quickly add common code: It can also be used to override methods and generate getters /setters and constructors.Ĭtrl+1 can be very handy in quick and smart fixes such as:Īssigning constructor parameters to new or existing class fieldsĪssigning a statement to a local variable Use Ctrl+Space and Ctrl+1 for Content Assist and Quick FixesĬtrl+Space allows for auto-completion. The search can be filtered by file type and scope of the search, such as searching only the selected project.ħ. This is really helpful if you want to search files in your workspace for text.

HOW TO USE ECLIPSE DEBUGGER FOR JUNIT CODE
Here are a few shortcuts to help to understand your code (using Windows). This seemingly minor detail helps me avoid typing too many characters and then hitting return to find what I want. When you hit Ctrl+F to find text in a source file, check the Incremental checkbox in the search dialog to make the occurrence of the searched text appear as you type. Set The "Incremental" Option in the Search Dialog Only when I have too many working sets, or I have projects that considerably differ from each other that I rarely switch between, then I separate them in different workspaces. This reduces memory consumption in the IDE and makes it as if these closed projects do not exist in your workspace anymore until you re-open them. In this case, I can simply close a working set by right-clicking on it from the Package Explorer and selecting Close Project. I often end up with many working sets containing projects I'm not using. One thing that you may need to do is change the Package Explorer view to view these working sets as shown below. For example, I typically keep a working set for sample projects for quick experimentation, and then typically a working set for each group of related modules in a Maven project. It also keeps your projects organized and accessible from within the same view.
HOW TO USE ECLIPSE DEBUGGER FOR JUNIT WINDOWS
This way you don't have to switch workspaces or have two Eclipse windows using different workspaces. But before reaching that level, you can just group related projects into a working set. If you work on many different projects, at some point you may need to use multiple workspaces to separate them. Group Related Projects in Working Sets Before Choosing Multiple Workspaces Go to Window -> Preferences -> Keys, then search for "Next editor" and "Previous editor", and override their bindings to Ctrl+Tab and Ctrl+Shift+Tab respectively (note: I'm using Windows). If you're used to switching tabs in browsers and editors like Notepad++, then do yourself a favor and change the keybinding for switching between Java source files. You can find a list of Java tooling improvements in Oxygen here.

Showing the last returned value while debugging a Java program. There are many improvements in the last release of Eclipse alone, and with the latest build released just a few days ago, the IDE supports Java 9 out of the box. These features don't require any plugin to be installed if the very first tip is followed. In this post, I'd like to share my favorite features in Eclipse that help me be more productive in my daily work as a Java developer. Especially those in the Java ecosystem, where Eclipse provides a solid environment for developing, debugging and running applications. With over 10 years of releases and countless extensions and plugins, Eclipse remains one of the most popular IDEs for developers working across several domains.
