Running Scripts with scala
You can run a Scala file straight from the terminal without any extra steps. It is like pressing play on a saved song instead of building the speaker first.

Syntax
scala FileName.scalaRunning Scripts with scala
The scala command can directly run a .scala file without a separate compile step, making it convenient for quick scripts, though it compiles internally before running.
For larger projects, scalac compiles to .class files ahead of time, which then run faster on repeat execution. Judge0 compiles your submitted code with scalac before running it.
Note:
scala file.scala compiles and runs a script in one command, ideal for quick, one-off programs.Example: Running Scripts with scala
object Main extends App {
println("This program was compiled and run via the scala toolchain")
}Login to try C/C++/Java/PHP code in the editor

Common Mistakes
- Running
scala Helloon a file name with no.scalaextension, so the file is not found. - Defining a
mainmethod without anobject, so the script has no entry point to run. - Expecting the script to be fast on repeated runs, when it recompiles each time; use
scalacfor a compiled build.
