本资料包系统性地探讨了Java编程语言中程序流程控制的核心机制,重点解析了条件判断语句(if-else、switch)和循环结构(while、do-while、for)的语法、特性及应用。通过对不同控制结构在解决实际问题(如实现猜数字游戏、打印九九乘法表、数据...
The Java SE 7 Advanced Platform, available for Java SE Suite, Java SE Advanced, and Java SE Support customers, is based on the current Java SE 7 release. For more information on installation and licensing of Java SE Suite and Java SE Advanced, visit Java SE Products Overview. See the fol...
Autoboxingis the automatic conversion that the Java compiler makes between the primitive types and their corresponding object wrapper classes. For example, converting anintto anInteger, adoubleto aDouble, and so on. If the conversion goes the other way, this is calledunboxing. Here is the simple...
You have seen the use of theprintf()andformat()methods to print output with formatted numbers. TheStringclass has an equivalent class method,format(), that returns aStringobject rather than aPrintStreamobject. UsingString'sstaticformat()method allows you to create a formatted string that you can...
In programs written in the Java programming language, hexadecimal numbers must be preceded with 0x. See also octal. hierarchy A classification of relationships in which each item except the top one (known as the root) is a specialized form of the item above it. Each item can have one or...
Besides just entering program lines, BASIC has special commands for modifying programs. EDIT allows you to modify the specified line. RENUM automatically renumbers the program lines, which is necessary if you need to add a new program line between two existing lines with consecutive numbers. You...

Java PathExplorer, developed by Havelund and Roşu (Havelund and Roşu, 2004), uses the rewriting-logic based model checker Maude to check LTL on finite execution traces of Java programs. The authors provide different semantics for LTL formulas in order to avoid cycle detection. Java PathExplo...

JVM allows Java to be run everywhere, so programmers only need to write code once to run it on multiple platforms. C# runs on Common Language Runtime and can run on Windows and Unix-based operating systems. To run Java, programmers need Java Development Kit, or JDK, while C# uses the...
