00:00:00,610 --> 00:00:02,060
- [Instructor] In this
Self Check exercise,

2
00:00:02,060 --> 00:00:04,900
we'd like you to test
out replacing substrings

3
00:00:04,900 --> 00:00:08,310
by starting with this original
string containing spaces

4
00:00:08,310 --> 00:00:11,840
and replacing each space
with a space, two dashes,

5
00:00:11,840 --> 00:00:14,410
a greater than sign, and another space.

6
00:00:14,410 --> 00:00:17,040
So, go ahead and pause the
video to give that a shot,

7
00:00:17,040 --> 00:00:18,540
then come back for the answer.

8
00:00:22,861 --> 00:00:24,780
Okay, let's go ahead and reveal that.

9
00:00:24,780 --> 00:00:25,720
So as you can see,

10
00:00:25,720 --> 00:00:28,000
we're calling directly
on the string literal,

11
00:00:28,000 --> 00:00:30,780
its method replace, and
we're going to replace

12
00:00:30,780 --> 00:00:33,930
every space character with the string

13
00:00:33,930 --> 00:00:36,220
that we specified in
the problem statement,

14
00:00:36,220 --> 00:00:39,113
and indeed, there are the replacements.
