00:00:00,180 --> 00:00:05,970
If statements can use comparisons to control the flow of your code, a comparison is only useful when

2
00:00:05,970 --> 00:00:07,350
it's inside of an IF statement.

3
00:00:09,640 --> 00:00:13,480
So in this lesson, you're going to use statements to control how your code runs.

4
00:00:16,379 --> 00:00:21,750
As usual, we're going to start by creating a new class inside the Section three folder, create a new

5
00:00:21,750 --> 00:00:25,740
file named FLC Java and make sure the class has a main method.

6
00:00:31,960 --> 00:00:35,100
The if statement runs, it's code only if a condition is true.

7
00:00:36,730 --> 00:00:42,280
This is a comparison, but when a comparison is inside of a statement, we call it a condition.

8
00:00:45,270 --> 00:00:51,210
There are two parts to in a statement, the condition which can be true or false and the code inside

9
00:00:51,780 --> 00:00:54,150
which only runs if the condition is true.

10
00:00:57,490 --> 00:01:03,520
So inside of Java, we're going to make an invariable that stores a student's grade into grade is equal

11
00:01:03,520 --> 00:01:04,510
to 65.

12
00:01:10,350 --> 00:01:15,780
Then we're going to make an if statement if and inside the brackets, we're going to read a condition

13
00:01:15,780 --> 00:01:18,960
that checks if a grade is greater than 50.

14
00:01:22,730 --> 00:01:25,820
And inside the if statement, we're going to print.

15
00:01:28,770 --> 00:01:29,760
Great job.

16
00:01:32,070 --> 00:01:32,880
You passed.

17
00:01:37,270 --> 00:01:39,550
This code will only run if the condition is true.

18
00:01:41,950 --> 00:01:43,300
So we're going to run our code.

19
00:01:51,290 --> 00:01:53,480
And it ran the code inside the statement.

20
00:01:55,030 --> 00:01:59,690
That's because the grade 65 is bigger than 50, which makes the condition true.

21
00:02:00,340 --> 00:02:02,980
So the code inside the if statement runs.

22
00:02:08,830 --> 00:02:11,140
Now we're going to change the students grade to 45.

23
00:02:16,460 --> 00:02:17,510
Rewrite our code.

24
00:02:20,520 --> 00:02:21,900
And nothing happens.

25
00:02:23,840 --> 00:02:27,110
The grid is not bigger than 50, which makes the condition false.

26
00:02:27,440 --> 00:02:29,150
So Java skips the code.

27
00:02:32,770 --> 00:02:36,370
When the if condition is false, Jova runs the false statement.

28
00:02:40,670 --> 00:02:46,780
And if a statement looks like this, there is an if statement with a condition and an el statements.

29
00:02:51,260 --> 00:02:54,140
And when the condition is true, Juvy runs the estimates.

30
00:03:01,020 --> 00:03:05,970
And when the condition is false, Java skips the statement and runs the code inside else.

31
00:03:10,640 --> 00:03:16,910
So back in our code, if a student scores under 50, we want the app to say study hard next time, so

32
00:03:16,910 --> 00:03:18,350
we're going to add an else block.

33
00:03:21,150 --> 00:03:24,210
And inside will print study hard next time.

34
00:03:29,850 --> 00:03:30,930
Rerun your code.

35
00:03:36,200 --> 00:03:42,170
And this time the code inside the statement runs, never going to change the grade back to 65.

36
00:03:43,220 --> 00:03:44,540
We run your code once more.

37
00:03:47,820 --> 00:03:50,910
And this time at Prince, great job you passed.

38
00:03:54,550 --> 00:04:00,340
We need to be careful about putting in the right condition, let's assume that if 50 percent warrants

39
00:04:00,340 --> 00:04:04,300
a pass, but our condition checks if the grid is greater than 50.

40
00:04:06,370 --> 00:04:10,750
I'm going to change the grade to 50 and see what happens, rewriting my code.

41
00:04:14,340 --> 00:04:17,040
And that's not good, the condition is false.

42
00:04:17,070 --> 00:04:18,510
So the student fails.

43
00:04:22,170 --> 00:04:27,480
We need to fix our conditions is that the student policies, if they're great, as greater than or equal

44
00:04:27,480 --> 00:04:28,110
to 50.

45
00:04:29,270 --> 00:04:30,500
Let's rerun the code.

46
00:04:32,090 --> 00:04:34,910
And right on the student pass with a D minus.

47
00:04:36,750 --> 00:04:42,390
In this case, the grid is equal to 50, so the condition is true and this runs the code inside the

48
00:04:42,520 --> 00:04:43,200
statements.

49
00:04:47,230 --> 00:04:50,830
In this lesson, you learn to use if statements to control how your code runs.

50
00:04:52,690 --> 00:04:55,510
When the condition is true, Jova runs the if statements.

51
00:04:58,460 --> 00:05:03,470
When the condition is false, Java skips the statement and runs the code inside ls.
