Automatic Memory

Java is a very popular Object-oriented programming (OOP) language because of its platform independent and automatic memory release mechanism (or garbage collection). However, garbage collection also speeds CPU time and should be done after careful consideration. In the paper, memory usage behavior and run-time object characteristics, including heap and object size, object age and access frequency, are studied using several commercial benchmarks. The profiler design method and experiment detail are represented in the paper. The runtime object characteristics are very important to guide the employment of different memory management algorithm.

Abstract An object-oriented programming (OOP) technique is investigated in order to develop the framework for mechanical design automation systems. A task-oriented decomposition approach is applied to conceptualize the task-object (or task-performing-object) in which common behavior and communication protocols are encapsulated [1]. Each task in the entire design process, either controlling design strategies or performing design methods, is made into an object. The design method objects are implemented using Artificial Intelligence (AI) paradigms, such as artificial neural networks and expert systems. This report explains how OOP is integrated to develop a mechanical design framework (MDF). A single reduction gear box design process was used to identify some of the general tasks involved in mechanical design process. From this process the guidelines for developing task-objects for future systems are formed. Full details of these guidelines and an implementation example in Smalltalk on a PC are available in [7].

The Impact

The object-oriented programming paradigm has gained popularity in both industry and academia, and Java is becoming the language of choice. Yet, it can be a difficult language to learn, with many hurdles for novice programmers. This overview describes how Java was successfully introduced as the first programming language in an information technology master’s program at Bentley College. Careful consideration was given to a variety of factors, including when to introduce object-oriented concepts, which integrated development environment to use, and how to support students with minimal prior programming experience. The impact of these choices on the learning experience and the factors that led to the successful implementation of Java as a first programming language are described.

Better Than

Aimed at the problem of reading and controlling UG files by OpenGL in VC++ environment, a method of object-oriented programming is proposed. The OpenGL single document, multiple documents and visualization windows are created by using the classified idea in VC++ environment. PRT format data files of UG are converted to DXF format data files. Not only the conversion rate but also the conversion quality of different format data file are ensured by using the intermediate conversion format CGM and the problems of redundancy lines and view missing are prevented. DXF files are converted to 3DS files by 3DS MAX software. Controlling and redrawing of UG files in OpenGL are realized. The Object-oriented method is better than process-oriented program design method on the reliability and operability of procedure. The method has been applied in the virtual CNC milling system and provided a theoretical basis for the development of visualization system.

The object-oriented programming paradigm has gained popularity in industry and academia, and Java is becoming the language of choice. Yet, it can be a difficult language to learn, with many hurdles for novice programmers. This chapter describes our experiences transitioning to Java as the first programming language in an information technology Masters program. Careful consideration was given to a variety of factors, including when to introduce object-oriented concepts, which integrated development environment to use, and how to support students with minimal prior experience. The impact of these choices on the learning experience is described, and the factors that led to the successful implementation of Java as a first programming language are presented.

Model View

Object Oriented Software Development (OOSD) is a design technique that is used before the development and design of a software. This design method makes the system appears as a collection of objects to communicate with other objects by passing messages. The Model-View-Controller (MVC) has been inherited from Object-Oriented Programming (OOP) with the integration of Graphical User Interface (GUI) and interactive program execution. The MVC is very useful for developing Interactive and Dynamic Web Applications and iOS. With MVC, developers can trust on design patterns that are widely accepted as solutions for recurring problems. MVC can be used to develop flexible, reusable and modular Software. Applying the MVC design pattern in object-oriented Software development a flexible, reliable, modular and scalable website can be built. So, it’s necessary for every developer to have the knowledge of software development using MVC design pattern.

A Performance

In programming languages with automatic memory management garbage collection plays an important role of cleaning unused memory. Garbage collection algorithms have been developed for many years and aim to maximize the application’s performance. This paper presents and compares a performance of five garbage collection algorithms present in current version of Java 12 in three applications with different object lifetime span. The analysis covered the system responsiveness, garbage collector workload and application throughput at high application load.
