1. A new chapter on databases: New to this edition is Chapter 15, “Databases.” This chapter introduces the student to databases and SQL using Java DB.
2. New Java 7 topics added: This edition discusses some of the new language features added in Java 7. Specifically, the ability to switch on a string expression is discussed in Chapter 4, and type inference is discussed in Chapter 7.
3. Improved organization in Chapter 4: The section covering the if/else if statement has been simplified and now appears immediately following the section on nested if statements. These sections have been rewritten to highlight the similarities between an if/else if statement and a nested i f statement.
4. A new section on System.out.printf: This new section has been added to Chapter 2 .
5. New In the Spotlight sections: Many of the chapters have new sections titled In the Spotlight . Each of these provides a programming problem and a detailed, step-by-step analysis showing the student how to solve it.
6. Online VideoNotes: An extensive series of online VideoNotes have been developed to accompany this text. Throughout the book, VideoNote icons alert the student to videos covering specific topics. Additionally, one Programming Challenge at the end of each chapter now has an accompanying VideoNote explaining how to develop the problem’s solution. The videos are available at www.pearsonhighered.com/gaddis.
7. Additional programming problems: Additional Programming Challenge problems have been added to most chapters. Several of these are simple games that will challenge and motivate students.

身為一個正在準備就業的資訊科學生,我對Java的掌握程度至關重要。《STARTING OUT WITH JAVA: EARLY OBJECTS 4/E (PIE)》這本書,為我打下瞭非常堅實的基礎。我尤其欣賞書中在物件導嚮程式設計(OOP)部分所花費的篇幅和講解的深度。作者並沒有一味地強調語法,而是花瞭很多時間去解釋OOP的核心思想,例如封裝、繼承和多型。透過大量的圖示和實際的應用情境,我能更深刻地理解這些概念在真實世界中的體現,並且知道如何在程式碼中有效地運用它們。書中的專案練習也很有份量,它們不僅是單純的練習題,更像是小型的軟體開發專案,讓我能夠將所學到的知識融會貫通,並在實踐中學習如何組織和設計程式碼。我發現,透過這些專案,我不僅學到瞭Java的語法,更學到瞭如何「思考」一個程式該如何被建構。這對我將來進入職場,解決實際的軟體開發問題,非常有幫助。
评分我對《STARTING OUT WITH JAVA: EARLY OBJECTS 4/E (PIE)》這本書的評價,可以用「驚喜」兩個字來形容。我原本預期它會是一本比較枯燥乏味的教科書,但實際閱讀後,卻發現它遠超我的想像。書中對於物件導嚮概念的講解,真的是我讀過最清晰、最容易理解的版本之一。作者巧妙地將複雜的理論,轉化為生活中常見的例子,讓我能夠輕鬆地掌握這些核心概念。而且,書中提供的練習和實驗,非常豐富,涵蓋瞭從基礎語法到進階應用。我特別喜歡那些挑戰性的專案,它們不僅能鞏固我對知識的理解,更能激發我的創造力,讓我思考如何將所學應用到更廣泛的場景。對於初學者來說,能夠找到一本既有深度又不失趣味的學習材料,真的非常難得。這本書讓我對Java產生瞭濃厚的興趣,也更有信心去深入學習這個強大的程式語言。
评分老實說,以前對程式設計總是抱持著一種「很難學」的刻闆印象,尤其聽到Java,就覺得它一定很複雜。《STARTING OUT WITH JAVA: EARLY OBJECTS 4/E (PIE)》這本書,徹底打破瞭我的觀念。它以一種非常友善且循序漸進的方式,引導我進入Java的奇妙世界。我喜歡書中那種「學以緻用」的教學模式,每一個概念講解完,都會立刻搭配相應的程式碼範例,讓我能夠馬上看到實際的效果。而且,作者的文字錶達非常生動,不會讓人覺得枯燥乏味。書中一些小技巧的分享,也讓我受益匪淺,例如如何寫齣更簡潔、更有效率的程式碼,以及一些常見的程式設計陷阱。最讓我感動的是,書本的品質也非常好,紙質厚實,排版清晰,閱讀起來非常舒適。這本書不僅是學習Java的工具書,更像是一本引領我探索程式世界的好夥伴。
评分說實話,我一開始買這本書的時候,其實有點猶豫。市麵上Java的書那麼多,挑選起來真的有點眼花繚亂。但是,《STARTING OUT WITH JAVA: EARLY OBJECTS 4/E (PIE)》的目錄和介紹引起瞭我的注意,尤其是「Early Objects」這個標題,讓我感覺它可能是比較適閤初學者的。實際翻閱之後,我的感受更加肯定。書本的編排架構非常清晰,每一章節都圍繞著一個核心概念展開,並且會逐步引入更複雜的議題。作者在解釋物件導嚮的過程中,用瞭很多貼切的比喻,讓抽象的概念變得具體易懂,例如把物件想像成生活中的各種物品,類別則是這些物品的藍圖,這對我這樣剛接觸程式設計的人來說,真的是豁然開朗。而且,書中對於錯誤處理和調試的介紹也相當到位,讓我在遇到問題時,知道該如何去分析和解決,而不是隻能原地打轉。我覺得這本書最大的優點,就是它沒有把初學者嚇倒,而是用一種鼓勵的方式,引導我們一步一步地探索Java的世界。
评分哇,這本《STARTING OUT WITH JAVA: EARLY OBJECTS 4/E (PIE)》真是讓我驚豔!身為一個剛踏入程式設計領域的學生,我對Java完全是從零開始。一開始拿到這本書,坦白說,我有點擔心它會不會太過艱澀難懂,畢竟「物件導嚮」聽起來就不是那麼容易消化。但齣乎意料地,作者的寫作風格非常親切,就像一位經驗豐富的老師在旁邊細心地引導。書中的概念講解循序漸進,從最基礎的變數、資料型態,到迴圈、條件判斷,都解釋得非常清楚。讓我印象深刻的是,書裡麵的範例程式碼都非常實用,而且都附有詳盡的註解,讓我能夠快速理解每一行程式碼的作用。更棒的是,書中還設計瞭很多練習題,涵蓋瞭從簡單的數學運算到稍微複雜的資料結構應用,讓我能夠透過動手實作來加深對知識的理解。每次完成一個練習題,都有一種小小的成就感,也更有信心繼續往下學。對我這種新手來說,能夠找到一本既有係統又不失趣味的入門書,真的非常幸運!這本書絕對是開啟Java學習之旅的最佳夥伴。
