Eclipse stands out as one of the most renowned development environments for Java, equipped with all the essentials to build a Java project from scratch. To embark on a new project, the first step is to create it. While the process is straightforward, those who have installed Eclipse for another programming language might find creating a new Java project in Eclipse a bit confusing.
Steps
Install Eclipse IDE for Java Developers. During the initial setup of Eclipse, you'll be prompted to select an IDE (Integrated Development Environment). Opt for "Eclipse IDE for Java Developers." This will install the necessary files and tools for initiating a Java project.
- If Eclipse is already installed for a different programming language, you can add Java support directly within Eclipse. Click on the "Help" menu and select "Install New Software." Choose "All Available Sites" from the dropdown menu at the top, then type "java" in the Filter field. Check the box for "Eclipse Java Development Tools" and click "Next." Follow the instructions to download and install the Java tools. Once installed, Eclipse will restart.
Click "File" → "New" → "Java Project." The "New Java Project" window will open.
- If the "Java Project" option doesn't appear but Java Development Tools are installed, select "Project..." from the "New" menu. Expand the "Java" folder and choose "Java Project."
Assign a name to your project for easy identification by you and other users. You can always rename the project later if necessary or desired.
Choose the location to save your project files. By default, they are saved in the Eclipse folder. You can customize this location if preferred.
Select the Java Runtime Environment (JRE) you wish to use. If you intend to create a program for a specific JRE, choose that environment from the dropdown menu. By default, the latest JRE will be selected.
Select your project layout. You can opt to use the project folder or create separate folders for source and class files. Eclipse's default layout option is "Create separate folders..." However, you may need to adjust this based on your project's requirements.
Click "Next" to open the "Java Settings" window. This is where you specify additional sources and add libraries to your project.
Use the Source tab to specify the build path. The compiler relies on this path to build your program. You can create additional source folders, link to external sources, or add and remove folders from this build path. The compiler uses the build path to determine which sources to compile.
Use the Libraries tab to add libraries to your project. This tab allows you to include JAR files and select pre-built libraries for use. With the JAR import feature, you can also utilize libraries from other projects.
Click "Finish" to start working on your new project. You will be directed to your Java workspace. If you were working with another programming language before starting this project, you will be prompted to switch to the Java perspective to fully leverage the IDE's capabilities.
- Your project will appear in the "Package Explorer" pane on the left side of the window. If only the Eclipse Welcome tab is visible, click the small Java button on the left side of the window.

Tips
- If you need to adjust settings after creating the project, right-click on the project name and navigate to the desired option.
