00:00Next question we will do is find product of A and B

00:03We will give two numbers A and B

00:06And we will find out their product

00:08We will multiply A by B by the result

00:11We will find out this

00:13Return

00:14So for this we will make a function

00:16What will return type of function?

00:19Return type int

00:20Because we will make product and return it from the function

00:24What can we keep this function?

00:26We can keep the name of this function

00:28And what will happen in this function?

00:30There will be two parameters

00:32The first parameter will be integer A

00:36And the second parameter will be integer B

00:39And my job is to multiply both in this function

00:43So what will I do?

00:45I will make a third variable

00:47Which I will store A multiplied by B

00:50And here I will return my product variable

00:55I will always add public static

00:57Because this is my access modifier

00:59So I will return my product here

01:01What will I do in the main function?

01:03I will add call in the main function

01:05I will multiply

01:06I will pass in the multiply

01:07I will pass A

01:08I will pass A

01:09Or I can pass 3 or B

01:11I can pass 5

01:12So we can pass directly values in our java functions

01:16And then whatever output comes

01:18I can store that output

01:20In this new variable

01:23Prod

01:24Which I will do in the next

01:26Print

01:27So in this way my flow will be

01:29I have to make this function

01:30Which will be written

01:31In the main function

01:33I will call in the main function

01:35I will pass 2 values

01:36A and B

01:37And the answer is returned

01:39I will store it in this variable

01:41I will then print

01:43Print

01:44So let's write this function

01:46In the function

01:47First we will write public

01:49Static

01:50Int

01:51Because it will be return type

01:53Int

01:54The name we have to give

01:55Multiply

01:56In the multiply

01:57First we will have a parameter

01:59Integer A

02:00Then Integer B

02:01After that

02:02What will I do?

02:03I will make a variable

02:05Product

02:06In which I will store

02:07A multiplied by B

02:08And I will return

02:10Product

02:11Product

02:12What will I do in the main function

02:15In the main function

02:16I will make two variables

02:17Int A

02:18Which I will store

02:193

02:20Int B

02:21Which I will store

02:225

02:23Now I am going to call

02:24Multiply

02:25In the multiply

02:26I have passed the same A and B

02:27But since the call by value

02:28So A and B

02:29Is always copy and pass

02:30Multiply

02:31As I will return this function

02:32I will give the product

02:34I will store it here

02:36How will I store it?

02:38I will store it

02:39A variable

02:40In the prod

02:41Now I will do the value

02:42I will print

02:43A multiplied by B

02:45Is equal to

02:46Save

02:47And

02:48A multiplied by B

02:49Is equal to

02:50Save

02:51And

02:52So A multiplied by B

02:53Is equal to 15

02:54Because 3 multiplied by 5

02:56Is equal to 15

02:57Because 3 multiplied by 5

02:58Is equal to 15

02:59So

03:04In the whole code

03:05When I have to multiply two numbers

03:06I will simply

03:07Where

03:08I will multiply two numbers

03:09Here

03:10I will multiply 10

03:11And

03:1220

03:13So

03:14I will simply

03:16Call

03:17In the prod

03:18Now I will store a new value

03:20And

03:21What will I do?

03:23I will print it

03:24So

03:25Now I will have two multiplications

03:27And

03:28A into B

03:29First of all

03:3015

03:31Then

03:3210

03:33And

03:3420

03:35Which is

03:36200

03:37So

03:38When I will work

03:39Two numbers

03:40I will write a straight line

03:41Which I can call the multiply function

03:42Video

03:45And

03:46In

03:47The

03:48Of

03:49No

03:50No

03:51But

03:53You

03:54The

03:55likely

03:56That

03:57Was

03:58That

03:59Were

04:00Us

04:01You

04:02I

04:03I

04:04Not

04:05States

04:06Any

04:07You

04:08Any
