" Format String Syntax
Every method which produces formatted output requires a format string and an argument list. The format string is a String which may contain fixed text and one or more embedded format specifiers."
Spring 3.0.5 is now released and comes with the fixes of more than 80 minor issues and provided some enhancements and improvements to the Spring Expression Language (SpEL), annotation support, and embedded databases.
XStream is a simple library to serialize objects to XML and back again.
Features
Ease of use. A high level facade is supplied that simplifies common use cases.
No mappings required. Most objects can be serialized without need for specifying mappings.
Performance. Speed and low memory footprint are a crucial part of the design, making it suitable for large object graphs or systems with high message throughput.
Clean XML. No information is duplicated that can be obtained via reflection. This results in XML that is easier to read for humans and more compact than native Java serialization.
Requires no modifications to objects. Serializes internal fields, including private and final. Supports non-public and inner classes. Classes are not required to have default constructor.
Full object graph support. Duplicate references encountered in the object-model will be maintained. Supports circular references.
Integrates with other XML APIs. By implementing an interface, XStream can serialize directly to/from any tree structure (not just XML).
Customizable conversion strategies. Strategies can be registered allowing customization of how particular types are represented as XML.
Error messages. When an exception occurs due to malformed XML, detailed diagnostics are provided to help isolate and fix the problem.
Alternative output format. The modular design allows other output formats. XStream ships currently with JSON support and morphing.
Normally, array is a collection of similar type of elements that have contigious memory location. In java, array is an object the contains elements of similar data type. It is a data structure where we store similar elements. We can store only fixed elements in an array.
