Basics¶

Identifiers¶

An identifier is a name that you can use to define a class, field, a function or variable.

An identifier must follows all the below rules

it must start with a letter ('a' to 'z' , and 'A' to 'Z'), or an underscore
the following characters can be a letter, an underscore or a number

Class identifiers¶

To reference a class, you need tp add the .class suffix, like in Java. But note that you can only reference simple name of classes, this means that you need to import it first.

import java.util.concurrent.Callable
println(Callable.class)

println(Object.class)

Comments¶

You can comment your code in Marcel the same way you would in Java.

Define comments like you would in Java. // ... for a single line comment, and /* ... */ for a multi-line comment

// this function does stuff
doStuff()

/* this function
  does some
  other stuff
 */
doOtherStuff()
