ClassPublic.java is a Java .class file converter which makes a Java class public and non-final, its fields public, and its methods public and non-final. ClassPublic.java has a compact implementation, depending only on J2SE 1.5.0 or newer. ClassPublic.java can be used to increase interoperability and code reusability of a .class file whose .java source is not available or is not feasible to recompile.
Components 4 Java is a development tool for Java. It provides a framework to organize and separate different parts of code, and fills the gap between the class level and the library level as provided by the Java SE architecture. Additionally, you can organize your classes in well-separated and loosely coupled components. Those can be stuck together graphically into larger compositions. Finally, components and compositions will be distributed among Java archives as specified in assemblies.
