What is the difference between Step Into and Step Over in a debugger

Question

I want to debug the whole flow of a  Java  program  I see there are several options for stepping through my program  What is the difference between step into  and step over

User · Answer

step into will dig into method calls step over will just execute the line and go to the next one

User · Answer

Step Into The next expression on the currently-selected line to be executed is invoked  and execution suspends at the next executable line in the method that is invoked   Step Over  The currently-selected line is executed and suspends on the next executable line

When debugging lines of code  here are the usual scenarios     Step Into  A method is about to be invoked  and you want to debug into the code of that method  so the next step is to go into that method and continue debugging step-by-step   Step Over  A method is about to be invoked  but you re not interested in debugging this particular invocation  so you want the debugger to execute that method completely as one entire step   Step Return  You re done debugging this method step-by-step  and you just want the debugger to run the entire method until it returns as one entire step   Resume  You want the debugger to resume  normal  execution instead of step-by-step  Line Breakpoint  You don t care how it got there  but if execution reaches a particular line of code  you want the debugger to temporarily pause execution there so you can decide what to do    Eclipse has other advanced debugging features  but these are the basic fundamentals   See also   Free video tutorial  Eclipse and Java  Using the Debugger IBM DeveloperWorks Debugging with the Eclipse Platform IBM DeveloperWorks Learn the essentials of debugging

You can t go through the details of the method by using the step over  If you want to skip the current line  you can use step over  then you only need to press the F6 for only once to move to the next line  And if you think there s someting wrong within the method  use F5 to examine the details

Consider the following code with your current instruction pointer  the line that will be executed next  indicated by - gt   at the f x  line in g    having been called by the g 2  line in main    public class testprog       static void f  int x            System out println   quot num is  quot     x 0        lt - STEP INTO            static void g  int x    - gt       f x              f 1       lt ----------------------------------- STEP OVER            public static void main  String args              g 2           g 3       lt ----------------------------------- STEP OUT OF          If you were to step into at that point  you will move to the println   line in f    stepping into the function call  If you were to step over at that point  you will move to the f 1  line in g    stepping over the function call  Another useful feature of debuggers is the step out of or step return  In that case  a step return will basically run you through the current function until you go back up one level  In other words  it will step through f x  and f 1   then back out to the calling function to end up at g 3  in main
