00.01	નમસ્કાર.
00.02	Netbeans Debugger. પરના આ ટ્યુટોરીયલમાં સ્વાગત છે.
00.06	જો તમે પ્રથમ વખત 'Netbeans વાપરી રહ્યા હોય તો આગળના ભાગ અમારા 'Spoken Tutorialની વેબ સાઈટ જુઓ.
00.14	આ ડેમોનસ્ટ્રેટ કરવા માટે હું વાપરી રહી છુ લીનક્સ ઓપરેટીંગ સીસ્ટમ ઉબ્નટુ આવૃત્તિ v12.04,
00.21	અને Netbeans (નેટબીન્સ) IDE v7.1.1
00.26	આપણે બધા જાણીએ છીએ કે debugging પ્રોગ્રામ એ કાળજીપૂર્વક કરવો પડે છે.
00.31	તેથીdebugging' ટૂલ જાણીને અને તેના ફીચરો સાથે પરિચિત હોવાથી તમે મૂલ્યવાન સમય બચાવી શકો છો.
00.39	આ શક્તિશાળીdebugging ' ટૂલ ખૂબ જ ઉપયોગી છે,
00.42	ખાસ કરીને જ્યારે તમે મોટા પ્રોગ્રામ્સને કોડ કકરવા અથવા ચકાસતા હોવ.
00.46	આ ટ્યુટોરીયલ આપણે 'NetBeans ડિબગર' પૂરી પાડેલ કેટલાક ફીચરો શીખીશું.
00.53	આ ટ્યુટોરીયલ સાથે પરિચિત થવું પડશે.
00.55	debugging વિન્ડો
00.58	બ્રેકપોઇન્ટ્સ રૂપરેખાંકિત કરવા
01.00	સમીકરણો ઉકેલવા અથવા ઘડિયાળ સુયોજિત કરવી.
01.04	તમારા પ્રોગ્રામના અમલીક્ર્ણ માટે ટ્રેસીંગ વિકલ્પો.
01.17	અને ' debugger' ને કોન્ફીગર કરવા માટેના વિકલ્પો
01.12	હવે ચાલો શરુ કરીએ અને સેમ્પલ કોડ debug કરીએ.
01.17	Netbeans IDEપર જાઉં છુ.
01.20	મેં ડેમોનસ્ટરેશન કરવા માટે IDE માં પહેલેથી જ sampleDebug જાવા એપ્લીકેશન બનાવ્યું છે.
01.27	This is a small program that initializes three integer values . આ નાનો પ્રોગ્રામ છે જે a, b, અને c ત્રણ ઇનટીજર વેલ્યુઓને ઇનશીલાઈઝ કરશે.
01.35	પછી તે 'Hello World!' અને 'a'. ની વેલ્યુ પ્રિન્ટ કરે છે.
01.40	It also creates a class object 'SampleClass', which has a 'value' integer, as a private integer value.
01.52	Then, it computes the value of 'b' ,
01.55	and calls a function to compute the value of c,
02.00	and prints the values of 'b' and 'c'.
02.05	To start with the debugging, let us first set the breakpoint.
02.09	To set a breakpoint, click on the line number.
02.13	I will set at this line which prints Hello World!
02.18	Notice that the line at which a breakpoint is set changes it's colour to pink and is marked by a small square against its line number.
02.28	When you run the program in the debugging mode,
02.31	by clicking on the Debug Project button in the toolbar,
02.35	the execution of the program stops at the line at which the breakpoint is located.
02.41	So far, 'a's value has been set.
02.45	Hover on it to check it's value.
02.49	It indicates that it's value is 10.
02.52	You can see that there are some additional windows below the workspace.
02.59	There is a 'Variables' window that shows a list of variables and their values.
03.07	So far, only the variable 'a' has been initialized.
03.11	We can also look at the 'Output' window with the sample debug output.
03.17	There is no output yet.
03.19	There is also a 'Debugger Console' ' that says that the program hit a breakpoint on line 29 and has stopped there.
03.28	There is also a 'Breakpoints' window that tells you that a breakpoint has been set on line number 29.
03.36	Before proceeding, let us see how to add a watch.
03.40	For example, let us say I want to watch on the integer value 'aSample'.
03.48	In the 'Variables' window below the workspace, I will double-click on the Enter new Watch option and enter the name of the variable 'aSample.value'.
04.02	Click on OK.
04.06	So far 'aSample' has not been created so it says it does not know the value.
04.12	Once it executes the line we'll know what the variable contains.
04.16	In a similar way you can also watch and evaluate expressions.
04.21	Here I'm checking for b=a+10.
04.25	What if I wanted to know what a-4 is.
04.29	So let me go to the Debug menu in the menu bar, and select Evaluate expression option.
04.37	The 'Evaluate Code' window appears in the workspace.
04.41	Here I will enter the expression 'a-4'.
04.45	Click on the Evaluate Expression button here, and in the Variable window, it says 'a-4' s value is 6.
04.56	Let us now proceed and execute this single line of code.
05.00	To do that, choose the Step-Over button from the toolbar.
05.06	That should execute only that 1 single line of the code to print “Hello World”.
05.12	To see the output, go to the output window and choose the sampleDebug output window
05.17	That says, Hello World! a is 10.
05.22	The program has now stopped at the line to create a SampleClass object.
05.28	Now, I want to go into the constructor of the SampleClass.
05.32	To that I can choose the Step Into option from the toolbar.
05.41	Then I can choose Step Over and see that the value came inside the constructor call is now set to 10.
05.51	You can also check that by hovering on the variable.
05.55	When I Step Over again, we can see that this.variable is also set to 10.
06.03	To get out of this function I can either choose Continue, Step Over or Step Out.
06.11	Let me choose Step-Out to come out of the method.
06.14	And now I'm back to where the function call was made.
06.19	When I say Step-Over again, you will notice that aSample.value is now set to10.
06.27	This is what we were watching for.
06.30	Apart from Breakpoints and StepOvers, you can also stop the execution of the program at the line of the cursor.
06.38	For example, let me go into the function here and set the cursor to be on this line which says d=b-5; .
06.49	Now from the toolbar, choose the Run To Cursor option.
06.54	You will notice that the execution of the program gets into the function and stops at the line where the cursor is located.
07.05	You can see that it has computed the value of b, as 20.
07.10	And inside the variable window, it has set 'b' to be 20.
07.14	Now, I can choose Step Over again and d's value also gets initialized and becomes 15.
07.23	Now, I can either choose to return or completely finish the execution of the program.
07.29	Let me choose Step Out and come back to the function call.
07.36	When you hover on the getC() function, you'll notice that the function has returned a value of 15.
07.43	The variable 'c' has not yet been assigned that value.
07.47	So, when we Step Over and execute that line, 'c' will get a value of 15.
07.55	We can now check it in the variable window or hover on the variable to check it's value.
08.03	Now if you want to stop the debugging session, you can choose the Finish Debugger Session option from the toolbar.
08.12	If you want to continue the execution to the next breakpoint you can choose the Continue option.
08.19	Once you finish, you can also choose the Continue option to complete the execution of the remaining program.
08.25	Let me choose Continue here.
08.27	In the Output window, it shows me the output as: b is 20 and c is 15.
08.34	Now, this was a quick overview of the options of debugging on netbeans.
08.39	If you want any advanced feature settings, you can -
08.42	Go to Tools menu, click on Options, go to Miscellaneous option, click on the Java Debugger tab.
08.53	Here you can change settings for multi-threaded program breakpoint options.
08.59	Or have filters to decide on which methods you would want to step in.
09.07	Now to the assignment.
09.09	As an assignment, take any of your programs, excellent if it has already errors.
09.16	If not, introduce some errors with the logic or algorithm.
09.20	Set breakpoints in the code. Usually, you would set a break at the calling point of a function which you suspect has the error.
09.29	Use Step-Into to go into the function.
09.32	Use Step-Overs to execute the lines and make sure to inspect the values of variables in the variable window.
09.41	Add some watches to help you identify and correct the error.
09.45	Step-Out of the method.
09.48	Continue till you reach the next breakpoint.
09.51	And finally, Finish the debugger session and Run your application.
09.57	In this tutorial, we became familiar with the netbeans debugger.
10.02	We saw how to set breakpoints and watches.
10.06	Add expressions which we want to evaluate, while the code is running.
10.11	Trace execution of a program with Step-Into, Step-Over, Step-Out and Run-to-Cursor options.
10.19	Also saw how to configure the debugger for advanced debugging.
10.24	Hope this tutorial saves you a lot of time in your testing and debugging tasks.
