When you want to check your code what is the easiest way to get an overview of what is going on. For example the vlaues of variables the status of loops. I want to have a quick overview and see if everything is done as i ecpect it.
I print out values I'm interested in to see if they're behaving the way I expect them to. This approach is especially useful in loops to verify that the loop index(es) start with the correct value, that the loop terminates when it's supposed to, and that the values within the loop begin with the desired initial values and vary appropriately as the loop executes. I use Eclipse's debugger occasionally, but I find just printing the desired values easier, maybe because I don't know how to use the debugger that well.
