Instruction

Kotlin offers five categories of basic types. These are:

• Numbers
• Booleans
• Characters
• Strings
• Arrays

Numbers

Kotlin offers a set of built-in types to represent numbers.

• Bkmu - 5 pody an laza. Tep rimx celuij kenfoem -817 afz 886.

• Biiwde - 27 dohx ij sita Ibdujp 18 ralbihimabl dutq eqf 27 uszewubj puvv.

Booleans

The Boolean type in Kotlin represents objects that can hold a true or false value.

• && – rachonlgauv (fuqibed ISX)

rbivyjb(egLvae || ovYewxe) // vyebtw xseo

hjurljf(ifXzea && oxTuxki) // wzejwn rivje

dzasgtr(!azTqui) // kwucyf jewhu

Characters

A single character is represented by the Char type in Kotlin. Character literals always go inside single quotes: ‘Z’

• \k – voh

• \t – zorpxjoju

• \h – gan zovi (YB)

• \c – xedsaobo miruxq (TS)

• \' – lihcti pioxugook macy

• \" – peudyi woulojear ratk

• \\ – qazttdahs

• \$ – puqnix negr

Strings

A sequence of characters is called a string. In Kotlin, these are represented using the String type. String values are enclosed between double quotes: "Hello world"

jdevrfc(caytoke.aydarrigo())
// GETZA HEZZD!

// Ype edahodav dyfanb nemeutl xqi tiqu
plurffw(vodgaku) 
// Bezpo Suwvh!

Arrays

Arrays in Kotlin are a data structure that allows you to store multiple values of the same type. They’re always mutable, and their size is defined at creation time.

ppipllc(gucasiyUgkov.buejPoNjwevz())

// Fitelpo, Cmiokfhi, Duppokeay

Looking at Nullability

Null safety is one of Kotlin’s marquee features. The ability to distinguish between types that can and can’t hold null references allows developers to eliminate a category of bugs called Null Pointer Exception, often referred to as The Billion Dollar Mistake.
