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

	Inventor einstein = p.parseExpression(
			"new org.spring.samples.spel.inventor.Inventor('Albert Einstein', 'German')")
			.getValue(Inventor.class);

	// create new Inventor instance within the add() method of List
	p.parseExpression(
			"Members.add(new org.spring.samples.spel.inventor.Inventor(
				'Albert Einstein', 'German'))").getValue(societyContext);
