You put them at the code that you need to debug the operation of. Not really much more that can be said on that...

Maybe I will just say that you can only put breakpoints on lines of code that actually execute, ie. you can't put a breakpoint on a line that just defines a variable, as an example. Also, it may be obvious to some but generally it helps to put the breakpoint on some part of the code that executes *before* the part that you are interested in, so that you can see the state of your app before part in question and then "step" into the code. It's much easier to step forward in code than the step back to something that has already happened.

I am not very clear on this Step Into  esp if the line has chain of 5 different methods each method with argument of someother method call. How to come back once you 'Step Into'. Click Step Reurn or Resume?

say my line number 100 is like below where i put break point

String fInput = StringUtils.substring(input, inputStartIndex + fieldDef.getBeginIndex(), inputStartIndex + fieldDef.getBeginIndex(),  + fieldDef.getSize());

So i 'Step Into ' does i land into  fieldDef.getBeginIndex()?(If i say Step Return will i come back to line 100?)
If I click 'Step Into' do i land into  fieldDef.getSize() method?(()?(If i say Step Return will i come back to line 100?)
 So is it better to put break point at line 99.

Any good video tutorials on this to explain clearly?
