Extension Methods and Operators Extension methods enable you to add methods to existing types thereby providing additional functionality without the need
to edit or recompile the code.
Invoking a Method You can invoke a method in two ways: by using the invoke statement or by using the inline invocation syntax.
Operator Overloading in JVM COBOL You can overload operators to provide alternative behavior, or behavior for different operand types.
String Handling in JVM COBOL JVM COBOL provides a predefined Java string type and provides powerful techniques for handling strings.
Types and Type Conversion Types can be converted into other types using the AS syntax or a conversion operator.
Type Compatibility of .NET and JVM COBOL with Other Languages Many .NET COBOL and JVM COBOL types have a strict correspondence with types in other languages, such as binary-long and float-short.
For those that don't have a correspondence, there are alternatives.
