"《Think in Java》是Java开发技术的重要参考书籍,被誉为程序员的必备宝典。作者Bruce Eckel是Java领域的权威,该书已更新至第三版,反映了Java技术的最新发展。书中全面介绍了如何使用Java语言编写健壮、高效和灵活的程序,适合初学者和有经验的开发者。译者团队包括陈昊鹏、饶若楠、薛翔、郭嘉和方小丽,他们在翻译过程中力求忠实于原著,并提供了专业术语的标准译法,以帮助读者准确理解。尽管书中可能存在的错误和不妥之处,作者鼓励读者提出指正。前言部分提到,虽然技术革命不断,但编程的核心在于解决问题,而非技术本身。" 《Think in Java》这本书深入讲解了Java编程的精髓,不仅涵盖了语言基础,如类、对象、接口、继承、多态等面向对象编程概念,还涉及了高级主题,如集合框架、异常处理、输入/输出、线程、泛型、反射和注解等。通过实例和清晰的解释,读者能够学会如何运用Java的思想解决实际问题。 集合框架是Java编程中的关键部分,书中详细讨论了ArrayList、LinkedList、HashSet、HashMap等各种集合类的使用方法和它们之间的区别。异常处理是确保程序健壮性的重要手段,书中阐述了如何正确抛出、捕获和处理异常。输入/输出系统涵盖文件读写、流的概念,以及网络通信等方面,帮助读者理解数据传输的机制。 线程部分讲解了并发编程的基本概念,如同步、互斥和死锁,这对于开发多用户或实时系统至关重要。泛型的引入提高了代码的类型安全性和重用性,而反射允许在运行时检查和修改程序行为,提供了更大的灵活性。注解则是元数据的一种形式,能提供编译时和运行时的附加信息,简化代码并支持框架的自动化处理。 此外,书中还强调了设计模式,这是解决常见编程问题的成熟方案,如单例模式、工厂模式、装饰器模式等,这些模式帮助开发者写出可维护、可扩展的代码。 《Think in Java》不仅是一本学习Java语法的教程,更是一本引导读者理解编程思想、提升编程能力的宝典。无论你是Java新手还是经验丰富的开发者,都能从中受益匪浅,不断深化对Java的理解。

Write java code: Copy the files, small_weapons.txt, and large_weapons.txt from the assignment folder on Blackboard and save them to your folder. For testing purposes, you should use the small file. Use the large file when you think the application works correctly. To see what is in the files use a text editor. Nilesh is currently enjoying the action RPG game Torchlight 2 which is an awesome game and totally blows Auction House Simulator 3, oh sorry, that should be Diablo 3, out of the water. He has got a file containing info on some of the unique weapons in the game. The transaction file contains the following information: Weapon Name (string) Weapon Type (string) Damage (int) Weapon Speed (double) … To tell if one weapon is better than another you need to know the Damage Per Second (DPS) the weapon does, since weapons have a different attack speed. DPS is calculated by taking the damage value and dividing it by the attack speed.a) You will write a program that will allow Nilesh to load the file and display the weapon info and DPS of every weapon in the input file. When the user chooses to open a weapon file, they are required to type in the filename. It will then read the 4 values about a particular weapon and then display the 4 values to the console window on one line neatly padded along with the DPS of the weapon. This is repeated until the end of the file. b) Modify your code from a) so that the weapon information written to the console window is also written to a text file. The user should be able to specify the name of the file. Add a header to the beginning of the file which has column headers for each column. At the end of the text file display the total number of weapons in the file. c) Document your code appropriately and add your name and id number as comments at the top of your code. Please also submit this text file you have created. Enter the file you want to search end with .txt: large_weapons.txt 1 Blackfang Bludgeon Great Hammer 489 1.44 339.58333333333337 2 Bones 2 Boneshredder Great Axe 256 0.84 304.76190476190476 3 Comet's Tail Great Sword 872 1.2 726.6666666666667 4 Decapitator Great Sword 188 1.08 174.07407407407408 5 Demolisher Great Hammer 887 1.32 671.9696969696969
