Defining Variables in Scala

Two Types of Variables

• val (immutable)
• var (mutable)

Example: Immutable val

1

val hello = "Hello Scala"
hello = "Hello again" // ERROR: can only assign once
println(hello)

Note: val is not the same as const in C++. (See: Java final vs. C++ const.)

Example: Mutable var

1

var goodbye = "Hello Scala"
goodbye = "Goodbye Scala"
println(goodbye)
