3. Select "Edit Configurations..." from the dropdown menu.
4. In the Run/Debug Configurations dialog, click on the "+" icon to add a new configuration.
5. Choose the type of configuration you need (e.g., Application, JUnit, etc.).
6. Fill in the necessary details such as the main class, program arguments, and environment variables.
7. Click "OK" to save your configuration.

What Are the Common Types of Debug Configurations in IntelliJ?

IntelliJ supports various types of debug configurations, tailored to different development needs:

• Application: For standard Java applications.
• JUnit: For running unit tests.
• Spring Boot: For Spring Boot applications.
• Remote: For debugging applications running on remote servers.

How to Manage and Edit Existing Debug Configurations?

Managing existing debug configurations is just as crucial as creating new ones. To edit or manage your configurations:

• Enhance the accuracy of your tests.
• Ensure that your application runs smoothly without unnecessary interruptions.

How to Use Breakpoints Effectively in IntelliJ Debugger?

Breakpoints are a powerful feature in IntelliJ that allows you to pause the execution of your code at specific lines. Here’s how to use them:

1. Open your code file in the editor.
2. Click in the gutter (the left margin) next to the line number where you want to set a breakpoint.
3. Run your application in debug mode.
4. When the execution reaches the breakpoint, it will pause, allowing you to inspect variables and the program state.

What Are the Tips for Debugging in IntelliJ?

Here are some essential tips to enhance your debugging experience:

• Utilize the "Evaluate Expression" feature to test code snippets during debugging.
• Step over and step into functions to navigate through your code effectively.
• Make use of the "Watches" panel to monitor specific variables.
• Configure logging levels to capture detailed information during debugging.
