Guy Steele. They do not need to specify null value, since they are primitive types. What if we want to query the database for a list of all popular polls that are currently running?This is where the specification pattern come in handy. if write access to the named file is not allowed. Implements the write method of OutputStream. Things become worse if we want to combine constraints. This section applies to Java methods and constructors. Bill Joy. 131-162. Also includes classes for compressing and decompressing data using the DEFLATE compression algorithm, which is used by the ZIP and GZIP file formats. (This second section contains links to the documents published on the Internet.) The height of this rectangle. length Regards, Anayonkar Shivalkar (SCJP, SCWCD, OCMJD, OCEEJBD). Since a FileOutputStream object may be buffered either by the Java implementation or by the underlying operating system, errors writing to the file or file descriptor may only be exposed when flushing or closing the stream. The Package specification includes any specifications that apply to the package as a whole or to groups of classes in the package. Declarations for other inherited methods are also included here for convenience. The Java Compatibility Kit includes a test to verify each assertion, to determine what passes as Java Compatible TM . For example we would like to query the database for all popular polls that are still running.The answer to this is a variation of the composite design pattern called composite specifications. 2015-02-13 Legal Notice. They may not be completely accurate. In the time between those two dates users can vote among different choices. NumberFormatException - if the string does not contain a parsable double. Michael Scharhag In addition to the class specific requirements, there are overall Java platform API documentation requirements with respect to handling unchecked exceptions (exceptions that derive from java.lang.RuntimeException). If access to the named file is not allowed, the security exception thrown by the security manager checkWrite method will be surfaced here. This example demonstrates the Executive Summary (first paragraph). Using a composite specification we can combine specifications in different ways.To query the database for all running and popular pools we need to combine the isCurrentlyRunning with theisPopular specification using the logical and operation.

The additional stipulation on constructors is, not surprisingly, that all constructors must create a set that contains no duplicate elements (as defined above).

Alexandre Mendes wrote:Really my question is pretty vague... "Leadership is nature's way of removing morons from the productive flow" - Dogbert Articles by Winston can be found here. Do you mean that people specify programs before creating them? This example demonstrates OS/Hardware Dependencies, Allowed Implementation Variances, and Cause of Exceptions.
