[[expressions-constructors]]
= Constructors

You can invoke constructors by using the `new` operator. You should use the fully
qualified class name for all types except those located in the `java.lang` package
(`Integer`, `Float`, `String`, and so on).
xref:core/expressions/language-ref/varargs.adoc[Varargs] are also supported.

The following example shows how to use the `new` operator to invoke constructors.
