When debugging with IntelliJ IDEA, what do the different variable colors mean?
debugging, intellij-idea, java, variables
Solution
Red is the standard color for variables.
Blue indicates that a variable has changed while you're stepping through the code. If you continue to the next iteration of your loop (assuming offlineNotifications is a Collection), you will see those are the variables manipulated in the current execution of code.
Problem
So when debugging with IntelliJ IDEA, the Variable Window often looks like this: (the white box is added by me afterwards) Now i have some variables colored red, others colored blue. Whats the meaning of the color, what is difference between these colors? I have also noticed red variables with blue fields and the other way around. I didnt find anything on the web about this.
