英语翻译
The purpose of this book is to teach you the fundamentals of programming.Along the way,you will become quite familiar with a particular programming language called Java,but the details of that language are not the main point.Programming is the science of solving problems by computer,and most of what you learn from this text will be independent of the specific details of Java.Even so,you will have to master many of those details eventually so that your programs can take maximum advantage of the tools that Java provides.
From your position as a new student of programming,the need to understand both the abstract concepts of programming and the concrete details of a specific programming language leads to a dilemma:there is no obvious place to start.To learn about programming,you need to write some fairly complex programs.To write those programs in Java,you must know enough about the language to use the appropriate tools.But if you spend all your energy learning about Java,you will probably not learn as much as you should about more general programming issues.
Moreover,Java was designed for experts and not for beginning programmers.There are many details that just get in the way if you try to master Java without first understanding something about programming.

这本书的目的是教会你编程的基本原则.顺此路,你就会逐渐对一种特殊的被称为爪哇的编程语言,非常熟知.但是关于那种语言的一些详细内容并不是此书测重点.程序编制是一门用电脑解决问题的科学.且你从此书中学到的大部分东西将是有关爪哇的一些独立的具体细节.但即使如此,你也要完全掌握大部分的细节描述,这样你就能最优地利用爪哇提供的工具.
从你作为一个程序编制的新生的立场看,你对理解和掌握编程及编程语言的具体细节这两个抽象概念的需要,将带你走进一个窘境,就是没有明显的切入点.要学习编程,你需要写一些极其复杂的程序.要想用爪哇写那些程序,你必须完全了解爪哇语言,目的是选择最适合的工具.但是如果你浪费大量的精力来学习爪哇的话,你将必然对编程问题学习不充足.
此外,爪哇是为专家能手,而不是为了程序初学者设计的.如果你在试图对程序一无所知的情况下掌握爪哇,你的学习之路将布满荆棘.
