Char and Boolean in Kotlin

Char type

• Characters are represented by the Char keyword.
• They cannot be treated directly as numbers but you can perform explicit conversion functions according to your needs. Let’s understand this by example.

char a = 65  // Compile time error.
This code works fine in Java but will throw error in kotlin.

• Character literals go in single quotes like ‘V’, ‘J’ etc.
• In kotlin, strings are represented by the String class. String literals go inside the double quotes like “Viveki”, “Jay” etc.
• Special characters can be escaped using a backslash.

The following escape sequences are supported:

• \t — To print tab
• \b — To use a backslash
• \n — newline character
• \r — carriage return
• \’ — To print single quote
• \” — To print a double quote
• \\ — To print a backslash
• \$ — To print the dollar sign
• To encode any other character like hexadecimal or binary use Unicode escape sequence syntax: ‘\uFF004’.

Boolean Type

• Boolean values are represented by Boolean keyword.
• Boolean has two values either true or false. Both must be in lower case and cannot represent as 0 and 1.

So, guys, that’s it for char and boolean in kotlin. Feel free to let me know if I missed something.
