Print and println output in Kotlin - Mini Project: Build & Apply

Print and println output

📖 Scenario: You are learning how to show messages on the screen using Kotlin. This is like writing notes on a paper to share with friends.

🎯 Goal: You will write Kotlin code to print messages using print and println functions and see how they behave differently.

📋 What You'll Learn

Create a variable with a message

Use print to show the message without moving to a new line

Use println to show the message and move to a new line

Print multiple messages to observe the difference

💡 Why This Matters

🌍 Real World

Printing messages is the first step to communicate with users in programs, like showing instructions or results.

💼 Career

Understanding how to display output is essential for debugging and user interaction in software development.

1

Create a message variable

Create a variable called message and set it to the text "Hello, Kotlin!"

Kotlin

# Create a variable called message with the text "Hello, Kotlin!"
# Your code here

Need a hint?

Use val to create a variable that does not change.

2

Print the message using print

Use print(message) to show the message without moving to a new line

Kotlin

val message = "Hello, Kotlin!"
# Use print(message) to show the message without a new line
# Your code here

Need a hint?

print shows text but stays on the same line.

3

Print the message using println

Use println(message) to show the message and move to a new line

Kotlin

val message = "Hello, Kotlin!"
print(message)
# Use println(message) to show the message and move to a new line
# Your code here

Need a hint?

println shows text and moves to the next line.

4

Print multiple messages to compare

Print print(message) followed by println(message) and then println("Done") to see how lines change

Kotlin

val message = "Hello, Kotlin!"
print(message)
println(message)
# Print println("Done") to show Done on a new line
# Your code here

Need a hint?

Observe how print and println affect the output lines.
