Eclipse comes with a built-in tool called “Debug” that lets you find and fix errors in your code. You can use this feature to, among other things, step through your code, set breakpoints, look at variables, and evaluate expressions.
To use Eclipse’s Debug feature, you can:
- Double-clicking in the left margin of the editor or right-clicking on a line of code and choosing “Toggle Breakpoint” will set a breakpoint.
- Right-click on a Java file and choose “Debug As” > “Java Application” or press F11 to start the debugging session.
- Once the debugging session is started, you can use the “Resume” button to run the code until the next breakpoint or the “Step Into,” “Step Over,” and “Step Return” buttons to step through the code one line at a time.
- You can also look at the values of variables and evaluate expressions at runtime by using the “Variables” and “Expressions” views.
- You can also use the Debug feature with each language by installing the plugin for that language.
This feature can help you find and fix mistakes in your code, especially when you’re working on complicated projects or large code bases. It can also help you be more productive and efficient when using Eclipse by making it easy to find problems in your code and fix them quickly.
