00:00Hi everyone, today we are going to study the chapter. It's called functions or methods.

00:05First of all, what is the name of the functions? What is coding?

00:08We will listen to the functions many times. Today we are going to understand what functions are actually and how we can write the functions.

00:15Let's say, we have seen a remote in the house. Now we know how the remote is in the house.

00:21The remote is like this, where there are many buttons inside. And every button is a specific work.

00:26I know that if I want to increase the volume, then I have to press this button.

00:32If I want to reduce the volume, then I have to press this button.

00:38If I want to mute the TV, then I have to press this button.

00:42If I want to close the TV, then I have to press another button.

00:46On the remote, there are fixed buttons.

00:49I know that if I want to do any work, if I want to mute the TV, then I will press the button.

00:56Then I will press the button and it will be done.

00:58Once again, we don't write the logic.

01:00What is the logic?

01:01Once again, we have to write the mute button.

01:04We just use that logic.

01:06Once again, we don't know the logic.

01:07Once again, we don't know what to mute the TV.

01:10Once again, we will learn the same thing.

01:12If we replicate the same thing in code, then we can replicate it with the help of functions.

01:20In English, functions means a work or particular function.

01:25We call functions.

01:28In Java, functions are a block of code.

01:31It is a block or a group that performs a particular work.

01:38We can do it with that particular task.

01:42Once again, when I have to do it, I will do it with my code.

01:46I have created a block in which it is the logic of the work.

01:50Once again, I can do it with this block.

01:55Functions are a reusable part of code.

01:58It is a part in which we have written a logic in the code.

02:01Now, we can perform a particular function with that part.

02:06I will not tell logic every time.

02:08Every time, we have to do it.

02:10If I can imagine my code as a button,

02:13this is my Java code.

02:15I have written a logic in it.

02:17I have written a logic once again.

02:19Once again, I have to call the mute functions.

02:21Once again, I will call it.

02:22Once again, it means press the button.

02:25Once again, the mute functions will perform.

02:28Once again, I will call it.
