Typechecking Java Protocols with [St]Mungo 215 Fig. 1. State machine for CProtocol 216 A. L. Voinea et al. The send and receive operations given in the client's local protocol are trans- lated as typestate methods in CProtocol.protocol. For example, the message request(str) to S (...
2. Understanding Type Safety in Java Collections Type safety in Java collections is essential for preventing runtime errors and ensuring that a collection only contains elements of a specific type.Java generics, introduced in Java 5, provide compile-time type checking, enabling us to define collecti...

Rethrowing Exceptions with More Inclusive Type Checking The Java SE 7 compiler performs more precise analysis of rethrown exceptions than earlier releases of Java SE. This enables you to specify more specific exception types in thethrowsclause of a method declaration. ...

This work contributes to three distinct elds of formal reasoning: It contributes to our understanding of Java from a formal perspective, acting as a highly detailed analysis of ...

You can use multiple type-checking modules where each module checks for a different kind of error. In this way, you can build on top of the Java type system, adding specific checks when and where you want them. With the judicious use of type annotations and the presence of pluggable type...
