Kotlin variables complete tutorials.
In order to create a variable, the compiler needs to know three things:
1. What the variable’s name is.
2. Whether or not the variable can be reused.
3. What type of variable it is.
Use var to define a variable whose value may change.
Use val to define a value whose value will stay the same.
Kotlin's ability to infer the type is called type inference.
Explicitly declare a variable’s type:
var x: Int = 3
The Kotlin compiler will only let you assign a value to a variable if the value and variable are compatible. If the value is too large or it’s the wrong type, the code won’t compile.
Every numeric type has the following conversion functions: toByte(), toShort(), toInt(), toLong(), toFloat() and toDouble().
In Array, Declaring a variable using val means that you can’t reuse the variable for another object. You can, however, still update the object itself.
