Integration with Java

Besides using the language Scheme, Java object fields and methods can be accessed using code such as: . This will invoke a Java method, and does the same thing as in Java. An object's fields can be accessed with: or . Static (class) methods can be invoked with the function . Kawa can be extended with Java code (by creating scheme functions in Java), and combined with other JVM implementations.
