00:00.000 --> 00:06.000
Methods and Functions

00:06.000 --> 00:13.000
In this video we will understand, explain what methods are and why they are useful in programming.

00:13.000 --> 00:18.000
Define and call methods with and without return values.

00:18.000 --> 00:26.000
Apply parameters, arguments, and return statements to solve simple problems.

00:27.000 --> 00:30.000
What are methods?

00:30.000 --> 00:34.000
Methods are blocks of code that perform a specific task.

00:34.000 --> 00:39.000
They help make programs easier to read, reuse, and maintain.

00:39.000 --> 00:43.000
Write code once, use it many times.

00:43.000 --> 00:47.000
Break down large programs into smaller parts.

00:47.000 --> 00:53.000
Keep code organized and less repetitive.

00:53.000 --> 00:57.000
Defining and calling methods.

00:57.000 --> 01:00.000
In Java, methods follow a simple structure.

01:00.000 --> 01:02.000
Examples.

01:02.000 --> 01:04.000
A method with return type.

01:04.000 --> 01:08.000
A method without return type.

01:08.000 --> 01:12.000
To call a method.

01:12.000 --> 01:17.000
Parameters, arguments, and return.

01:17.000 --> 01:22.000
Parameters, inputs, and method takes.

01:22.000 --> 01:26.000
Arguments. Actual values passed when calling.

01:26.000 --> 01:30.000
Return statement sends a value back to the caller.

01:30.000 --> 01:33.000
Example.

01:33.000 --> 01:38.000
Calling.

01:38.000 --> 01:42.000
Best practices and exercises.

01:42.000 --> 01:46.000
Use clear names for methods like add, calculate area.

01:46.000 --> 01:49.000
Keep each method focused on one task.

01:49.000 --> 01:53.000
Test methods to check if results are correct.

01:53.000 --> 01:55.000
Practice ideas.

01:55.000 --> 02:00.000
Create utility methods for addition, subtraction, multiplication.

02:00.000 --> 02:04.000
Combine them into a simple calculator program.

02:04.000 --> 02:09.000
Write test cases to verify answers.

02:09.000 --> 02:13.000
Methods make Java programs organized and efficient.

02:13.000 --> 02:18.000
They let us reuse code, use parameters, and return results.

02:18.000 --> 02:21.000
With simple examples like a calculator,

02:21.000 --> 02:25.000
methods keep programs clear and powerful.
