String comparison (equals, compareTo) in Kotlin - Mini Project: Build & Apply

String comparison (equals, compareTo)

📖 Scenario: You are creating a simple program to compare two names to see if they are the same or which one comes first in alphabetical order.

🎯 Goal: Build a Kotlin program that compares two strings using equals and compareTo methods and shows the results.

📋 What You'll Learn

Create two string variables with exact names and values

Create a boolean variable to store the result of equals comparison

Use compareTo to find the alphabetical order difference

Print the results exactly as instructed

💡 Why This Matters

🌍 Real World

String comparison is useful in sorting names, searching text, and validating user input in many apps.

💼 Career

Understanding string comparison helps in writing code for data processing, user authentication, and UI sorting features.

1

Create two string variables

Create two string variables called name1 and name2 with the exact values "Alice" and "Bob" respectively.

Kotlin

# Your code here

Need a hint?

Use val to create variables and assign the exact string values.

2

Create a boolean variable for equals comparison

Create a boolean variable called areEqual that stores the result of name1.equals(name2).

Kotlin

val name1 = "Alice"
val name2 = "Bob"
# Your code here

Need a hint?

Use the equals method to compare name1 and name2.

3

Compare strings alphabetically using compareTo

Create an integer variable called compareResult that stores the result of name1.compareTo(name2).

Kotlin

val name1 = "Alice"
val name2 = "Bob"
val areEqual = name1.equals(name2)
# Your code here

Need a hint?

Use the compareTo method to compare name1 and name2 alphabetically.

4

Print the comparison results

Print the values of areEqual and compareResult using two separate println statements.

Kotlin

val name1 = "Alice"
val name2 = "Bob"
val areEqual = name1.equals(name2)
val compareResult = name1.compareTo(name2)
# Your code here

Need a hint?

Use println to show the boolean and integer results on separate lines.
