Join David Gassner for an in-depth discussion in this video Debugging with IntelliJ IDEA, part of Java Essential Training.
- All good integrated development environments for Java…provide debugging capabilities.…The ability to set break points…and to watch variable values so that you can find out…where errors are occurring in your code.…I'll demonstrate how to do this in IntelliJ IDEA…in the debugging project.…This project has just a few lines of code.…I'm declaring a string value.…I'm then getting a character array from the string.…And then I'm stepping through the character array…using a for loop and I'm outputting one character at a time.…
When I run the application,…I see the string displayed vertically.…One character per line.…But now, I'm going to step through the code…one line at a time.…I'm going to add a break point.…I'll click once, to the right of my line numbers,…if they're displayed, but to the left of the code.…And I see a break point icon displayed.…If I move the cursor off the icon and then back again,…I'll see some useful information about it.…Now, to run the code and hit the break point,…I'll run in debug mode.…
You can do this from the menu by choosing run, debug main.…
