Guess until you get it right

This example keeps asking the user for a number until the number is the correct one.

How to build

kotlinc src/**/*.kt -d build

How to run

kotlin -cp build project005.GuessKt

Noteworthy

• In this example we use another java class for the sake of the example: Scanner
• We had to import that class, since that one isn't from the java.lang package.
• Scanner deals with closeable resources, so we can use the use kotlin extension function.
• When we created the Scanner, we passed System.in as parameter. The backticks are escaping the in because it's a reserved word in kotlin but not in java. Kotlin also permits special identifiers using backticks in tests.
