Java ☕ Methods

This video tutorial introduces the concept of methods in programming, focusing on writing reusable code. It covers how to write a simple method in Eclipse, explains method returns, and discusses method parameters. The tutorial includes an activity on writing a Boolean method, demonstrating how to determine if a number is even or odd. The video aims to make viewers comfortable with creating and using methods in their code.

What is the primary purpose of using methods in programming?

• To make the code run faster

• To allow code reuse and organization

• To increase the complexity of the code

• To reduce the number of variables

Where should a method be written in relation to the main method?

• In a separate file

• At the end of the program

• Outside the main method

• Inside the main method

• By writing the method name inside a loop

What does a method return when it is designed to return a value?

• Any of the above

• A string

• An integer

• A variable

What are method parameters used for?

• To determine the method's visibility

• To define the method's return type

• To provide input values to the method

• To specify the method's name

How are parameters passed to a method?

• Using the 'param' keyword

• Separated by commas

• As a single string

• In a separate file

What does the modulus operator (%) help determine in a number?

• If the number is positive

• If the number is negative

• If the number is even or odd

• If the number is prime

What will the Boolean method return if the input integer is even?

• True

• False

• The integer itself

• An error

What is the result of calling the 'isEven' method with the number 100?

• True

• An error

• False

• 100
