"《Think In Java》是一本深受Java程序员喜爱的经典教材,由Bruce Eckel撰写,旨在帮助读者深入理解和掌握Java编程,适用于初学者和有经验的开发者。本书的第三版针对Java技术的最新发展进行了更新,以帮助程序员编写健壮、高效、灵活的Java程序。译者团队在翻译过程中力求忠实于原著,对专业术语的翻译遵循标准,并提供了英文原文以助于理解。" 在《Think In Java》这本书中,读者将逐步学习到Java语言的基础知识,包括但不限于: 1. **Java语法基础**:如何声明变量、数据类型、控制结构(如if语句和循环)、函数等,这些都是编程的基础,也是Java初学者的入门知识。 2. **面向对象编程**:深入讲解类、对象、封装、继承和多态等核心概念,这是Java的核心特性,也是现代软件开发的关键。 3. **异常处理**:理解如何在代码中捕获和处理异常,提高程序的健壮性。 4. **集合框架**:介绍ArrayList、LinkedList、HashMap等数据结构,以及如何有效地使用它们来存储和操作数据。 5. **泛型**:理解如何使用泛型来增强类型安全性,减少类型转换的需要。 6. **多线程编程**:学习如何创建和管理线程,以及同步和通信机制,这对于构建高效的并发应用程序至关重要。 7. **输入/输出和网络编程**:了解Java如何处理文件操作和网络通信,为实现跨平台的分布式应用打下基础。 8. **反射和注解**:掌握Java的动态类型特性,以及如何使用注解来添加元数据,提升代码的可维护性和灵活性。 9. **高级主题**:如垃圾收集、内存管理和性能优化,这些知识有助于编写更高效的应用。 本书不仅涵盖了Java语言的广泛主题,还强调了“用Java的思想去考虑问题、解决问题”的编程思维方式,这使得即使是有经验的Java程序员也能从中受益,不断深化对Java的理解和应用。通过阅读和实践《Think In Java》,读者将能够应对实际开发中的各种挑战,提升自己的编程技能和解决问题的能力。

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
