Java Properties provides an efficient way to access bean-like properties of Java objects.

In a nutshell, provides an efficient way to access bean-like properties of java objects. Unlike java bean properties, a chain of properties can be specified efficiently, allowing convenient access to properties of nested domain objects.

Runtime class-generation and caching can be used very easily to obviate the need for reflection, without losing the flexibility it provides.

Class Properties It also provides classes which manipulate objects at runtime by using strings to address conceptual variables (think bean properties) in a similar fashion to the java reflection mechanisms.

Class Property example Say we have the following classes:

public class Order {
...
public Customer getCustomer() { ... }
...
}
public class Customer {
...
public Address getAddress() { ... }
...
}
public class Address {
...
public String getLine1() { ... }
public String getLine2() { ... }
...
}

Now, we could do this to access line 1 of the address:

result = order.getCustomer().getAddress().getLine1();

But what if there are nulls? What if we want to compare the first line of the address from two different orders? Whith properties this is really simple:

ClassProperty p = PropertyManager.getProperty(Order.class,"Customer:Address:Line1",true);
result = p.getValue(order);

The idea is simple enough - you use the string "Customer:Address:Line1" to specify a series of getXXX calls. Importantly, it the library handles nulls for you, returning null if any of the objects in the chain are null.

Note, this is not simply a wrapper around java reflection, since it includes non-reflective optimizations by making use of the cojen library to generate class files at runtime to acces these properties.

The real benefit lies in being able to specify which properties you wish to access at runtime. You can even pass this ability on to the users of your library or application. Unlike reflection, class files are generated for the properties, and these files are cached - which means once you have specified a property once, further uses of the same property dont use reflection and are very fast.

Property API vs Java Bean Properties. The property API models accessor/mutator method pairs as conceptual variables called properties. The approach used is similar to, but more flexible than java bean properties, and more performant than reflection if runtime class generation is used. Unlike java bean properties, a chain or path of properties can be specified (and more importantly, turned into bytecode using runtime generation) to traverse a complex tree of objects.
It is simple to create applications portable between different security environments - using runtime generation where allowed, and falling back to reflection where security is tighter.

Dynamic Class Management. The properties package also provides classes to handle the loading (and unloading/reloading) of classes at runtime. It provides a framework useful for dynamically loading runtime-generated classes, for example.
While the property API can happily ignore the dynamic loading framework, it can also make use of it to enable runtime class generation.

The Java Brainfuck Compiler is a compiler for the uniquely powerful Brainfuck language, which produces Java bytecode that will run on any Java Virtual Machine (with no intermediate steps such as going by way of Java code).

Java Tools is a lightweight integrated development environment for creating, compiling, and executing Java applications and applets.
Java Tools includes point and click access to the Java files, commands, and documents. It also includes a built-in text editor and user interface for the Java debugger.
It is intended for the new Java user who needs help getting started. Its also for the more experienced Java user who wants easy access to the Java commands and a text editor.
Main features:
- GUI with built-in help and small footprint.
- Point and click access to all files (Java, manifest, HTML, image and sound) and directories (package).
- Point and click access to all commands for compiling (javac), archiving (jar), documenting (javadoc), executing (java), debugging (jdb) and disassembling (javap).
- Point and click access to all documents (Java API Specification, Java Tools and Utilities, Java Features and Java Tutorial).
- Point and click creation of all files (Java, manifest and HTML) and directories (package).
- Point and click installation of distribution archive files (Java document, Java source code, Java Tutorial and Sun Tools).
- Automatic determination of class file dependencies for archiving (jar) and documenting (javadoc) Java files.
- Checking for unused, redundant and missing imports.
- Logging of all commands invoked by GUI.
- Code metrics for Java files.
- Built-in text editor (see Edit for details).
- Built-in user interface for the Java debugger with command-line editing and history.
- Self-installing executable (Java archive file).
- Comprehensive installation and user documentation for Java and Java Tools.

java-diff is a set of Java classes which implement the longest common subsequences algorithm.

java-diff compares the elements in two arrays, returning a list of Difference objects, each of which describes an addition, deletion, or change between the two arrays.

Java-GNOME application is a set of Java bindings for the GNOME and GTK libraries that allow GNOME and GTK applications to be written in Java.

The Java-Gnome API has been carefully designed to be easy to use, maintaining a good OO paridigm, yet still wrapping the entire functionality of the underlying libraries.

Java-Gnome can be used with the Eclipse development environment and Glade user interface designer to create applications with ease.

Java-Gnome is part of the official Gnome Bindings Release, commiting us to high quality regular releases.

Java::Swing provides a Perl extension providing direct access to the Java Swing API.

Though you can write a Java program which is driven by Perl, some people may prefer to keep their Perl pure. This package lets you do that in manner similar to the way Perl/Tk and Gtk2:: provide access to their underlying libraries. This lets us code in our favorite language, while using the graphical interface capabilities of Java Swing.

Once you use Java::Swing, you can refer to javax.swing classes by their class name alone as if it name were a Perl package name. All class methods, including constructors, can be called as normal through this Perl package name.

But, if you like, you may also use Java::Swing named attribute construction, as shown for the second JTextField above. Simply supply a hash reference whose keys are attributes of the class with the proper values. Your object will be constructed by calling the empty argument constructor. Then the attribute values will be supplied by calling set accessors. So columns => 10 will translate into setColumns(10).

As of version 0.12, you may add an Object attribute to the constructor hash. Then Java::Swing will call the constructor on the underlying class which expects it, and then call set accessors for any additional attributes.
