What is the method for defining variables in Kotlin?

In Kotlin, variables can be defined using the keywords var or val.

1. Variables defined using the var keyword are mutable, meaning they can be reassigned, similar to regular variables in Java.
   Example: var x: Int = 5
2. Variables defined using the ‘val’ keyword are immutable; once assigned a value, they cannot be changed, similar to constants in Java.
   Example: val y: String = “Hello”

In the above example, x is a mutable integer variable with an initial value of 5 that can be changed through assignment operations. On the other hand, y is an immutable string variable with an initial value of “Hello” that cannot be modified.
