Examples

The source code of the ShippingCost class demonstrates how easy it is to use Janino as an expression evaluator.

The ExpressionDemo class implements a command line-based test environment for the expression evaluator (see also its source code).

The ScriptDemo class implements a command line-based test environment for the script evaluator (see also its source code).

The ClassBodyDemo class implements a command line-based test environment for the class body evaluator (see also its source code).

The DeclarationCounter class implements a command-line utility that counts class, interface, field and local variable declarations in a set of Java^TM source files (see also its source code).
