All language subtitles for 003 Breakpoints_en

More often than not, you're going to get bugs.

So it helps to visualize the runtime using breakpoints in this lesson, you're going to learn how to

use breakpoints.

You can access this lesson from the resources if your resources don't include the following path, then

please download the updated resources from GitHub.

All right, inside the breakpoints class, we can start a debugging session to visualize the output

of each variable line by line.

So in this code, click the run and debug option.

And click on credit lines that Jason file, and here you can see the current file that we can launch

the debugger for, it's the file that corresponds to the breakpoints class.

Not that important, just showing you what's going on behind the scenes.

But what we want to do is we're going to place a breakpoint next to each line of code when we launch

the debugger for this file.

What it's going to do is it's going to stop at each break point and allow us to visualize the output

for that line.

Essentially, it's going to allow us to visualize the run time line by line, kind of like the animations

I've been showing you throughout the course, except now we can do it in voice code, which is really

cool.

So without further ado, click launch.

Current file.

Press continue to stop at each breakpoint.

And here in the left pane, you can visualize the output of each variable and long double boolean car

are primitive types and notice that each primitive store is a value.

And once you get to the last break point, if you press continue, it's just going to disappear because

debugging session is over.

So let's restart the session.

Go to the last line.

And a small little trick for you is to step over at the last line if you want to see it.

Now, string is a class type, you can see that the string variable contains an object with a bunch

of fields'.

One of the fields is an array that contains the ASCII representation of each character.

So what you would see is hello, but what's actually being stored is one hundred and four one two one

one.

Oh, wait.

Where each one corresponds to a character.

Again, this isn't that important.

It's just really cool that this code allows us to see exactly how each variable behaves.

In this lesson, you learn to visualize the output of a variable.

You visualized five primitives, each one stores of value, and you visualize the class type variable

which contains an object.
