Java language

JavaBeans was designed to distinguish properties, methods, and events without arty change to the basic Java language. It does this by using a facility called reflection. 

CORBA recently defined mappings for the Java language and aligned closely with Jav-aBeans and Enterprise JavaBeans for its component model. In fact, the Java Transaction Service is defined based on the CORBA model. 

The Java language provides a virtual machine that runs the same on all hardware.3 The public GUI classes in the Java library are the same for all hardware, but they are facades for a layer of peer classes that adapt to the local operating system.

Java RMI (remote method invocation) is offered as a part of the JAVA language specification and win be a language-dependent method for the distributed object environment. Although there is the constraint that aU the environments should be unified into Java, the developing process with it is a little easier than with CORBA or RPC because several functions for distributed computing are offered as utility objects.

LDG qualitatively tries to find cause and effect relationships between process deviations generated by HAZOP guide words. LDG HAZOP is a web-based multiclient expert system for HAZOP developed in Java language [4]. The main subunits connected to the user interface are the DOC and LDG modules. The DOC module is mainly used for the word processing unit. DOC modules consist of (1) result/report generation subsystems, (2) a document management subsystem, and (3) a hint generator.

This software is written in Java programming language. To run this Java application, the J2SE (v 1.4.2 or higher version) Java runtime environment must be installed. There is a free download web site http //iava.sun.eom/i2se/l.4.2/ download.html. The CASim software is designed to run on any computer that supports Java 1.4.2 or later Java runtime environment. (This includes almost all Windows, Macintosh, and linux systems.)... 

If you are investigating applications development, I advise you to explore Java or C as a possible programming language. Both Java and C are strong object-oriented applications development languages with a rich set of classes and methods to help you... 

Scatter search has been implemented in software called OPTQUEST (see www.opttek.com). OPTQUEST is available as a callable library written in C, which can be invoked from any C program, or as a dynamic linked library (DLL), which can be called from a variety of languages including C, Visual Basic, and Java. The callable library consists of a set of functions that (1) input the problem size and data, (2) set options and tolerances, (3) perform steps 1 through 3 to create an initial reference set, (4) retrieve a trial solution from OPTQUEST to be input to the improvement method, and (5) input the solution resulting from the improvement method back into OPTQUEST, which uses it as the input to step 7 of the scatter search protocol. The improvement method is provided by the user. We use the term improvement loosely here because the user can simply provide an evaluation of the objective and constraint functions. 

Two different navigation paths may refer to the same object for example, the object referred to as my boss may be the same object as that referred to as my friend s wife. In Figure 2.2, session-5.instructor and session-32.instructor both refer to the same object, laura. If both names refer to the same object, they both see the same attribute values and changes to those values, x = y means x and y refer to same object x <> y means that x and y refer to different objects. These symbols are based on the Object Constraint Language (OCL) in UML in C++ and Java we d use == and =. 

Our seminar scheduling application will have many classes in its implementation. One likely class is a calendar that tracks various scheduled events for various instructors. We start with two different Java implementations of the calendar. Then we show how the external behaviors can be specified independent of implementation choices and even of implementation language and technology. We will ignore any UI aspects. 

So there is a class layer of design described entirely in terms of classes, with related types, which can be implemented directly in a language such as Java, Eiffel, or C++ or otherwise by judicious application of class-to-nonclass patterns (see Figure 3.32). 

Various complications arise in inheritance from multiple classes. For example, both superclasses may define an operation for the same message, or both superclasses themselves inherit from a common parent, and each language will provide some consistent resolution convention. Java and standard Smalltalk prohibit multiple inheritance of implementations for this reason. 

Java also supports such a reflexive layer Classes, interfaces, methods, and instance variables can all be manipulated as runtime entities, although in a more restricted form than in Smalltalk. The language still needs work in this area. 

Eiffel is among the few programming languages to provide directly for operation specs, but they can, of course, be documented with an operation in any language. In C++, suitable macros can be used Java could use methods introduced on the superclass Object. For debugging, pre- and postconditions can be executed. 

CLOS is an exception Its operations are not attached to any particular receiver. As with Java and C++, there may be several operations with the same name and different parameter lists but the operation to be executed is chosen at runtime on the basis of the classes of all the parameters (not just the receiver, like the other languages). Catalysis works as well for CLOS as it does for Java and so on because multireceiver messages are a type of action.
