Print and println output in Kotlin - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the difference between print() and println() in Kotlin?

print() outputs text without moving to a new line, so the next output continues on the same line. println() outputs text and then moves to a new line, so the next output starts on the next line.

What will be the output of this Kotlin code?<br>

print("Hello")
print("World")

The output will be HelloWorld on the same line because print() does not add a new line after printing.

beginner

What will be the output of this Kotlin code?<br>

println("Hello")
println("World")

The output will be:<br>Hello<br>World<br>Each word is printed on its own line because println() adds a new line after printing.

beginner

Can you use print() and println() together? What happens?

Yes, you can mix them. print() will print text without moving to a new line, and println() will print text and then move to a new line. This lets you control exactly how your output looks.

How do you print a variable value in Kotlin using println()?

You can print a variable by placing it inside println() using string templates like this:<br>

val name = "Alice"
println("Hello, $name!")

This will output: Hello, Alice!

What does println() do after printing text?

A Moves to a new line

B Prints text without moving to a new line

C Deletes the printed text

D Prints text twice

println() prints the text and then moves the cursor to the next line.

What will this code print?<br>

print("Hi")
println(" there")

A Hi (on one line) and there (on same line)

B Hi (on one line) and there (on next line)

C Hi there (on one line)

D thereHi

print("Hi") prints 'Hi' without new line, then println(" there") prints ' there' and moves to new line, so output is 'Hi there' on one line.

Which function would you use to print text and stay on the same line?

A print()

B println()

C readLine()

D printlnLine()

print() prints text and stays on the same line.

What will this code output?<br>

println("A")
print("B")
println("C")

A A (line 1) B (line 1) C (line 2)

B A (line 1) B (line 2) C (line 3)

C ABC (line 1)

D A (line 1) BC (line 2)

println("A") prints A and new line, print("B") prints B on same line, println("C") prints C and new line. So line 1: A, line 2: BC.

How do you include a variable inside a string in println()?

A Using + to join strings

B Using $variable inside the string

C Using %variable%

D Using variable()

Kotlin uses string templates with $variable to include variable values inside strings.

Explain the difference between print() and println() in Kotlin and give an example of when to use each.

Think about how output appears on the screen line by line.

Describe how you can combine print() and println() to format output in Kotlin.

Consider how to keep some text on the same line and move to a new line after.
