How does java handle unicode characters?

由 风流意气都作罢 提交于 2021-02-08 04:23:12
问题 I read this blogentry regarding perl and how they handle unicode and normalization of unicode. Short version, as I understand it, is that there are several ways to write the identifier "é" in unicode. Either as one unicode character or as a combination of two character. And the perl program may not be able to distinguish between them causing strange errors. So that got me thinking, how does the Java editor in Eclipse handle unicode? Or java in general, since I guess thats the same question.

Eclipse “Correct Indentation” ignoring spaces vs. tabs setting

由 断了今生、忘了曾经 提交于 2021-02-08 03:36:49
问题 I'm running Eclipse Juno Service Release 2 (20130225-0426) in Windows and I'm finding that auto-indent (Ctrl-I) ignores both the General/Editors/Text Editors/Insert spaces for tabs and Java/Code Style/Formatter/Indentation/Tab policy="Spaces only" settings. With both of those set, Ctrl-I indents the code with a combination of tabs and spaces, even though Ctrl-Shift-F uses spaces only. The problem is I don't want Eclipse to reformat my code -- just correct the indentation with spaces. Is this

项目 内容 这个作业属于哪个课程 https://www.cnblogs.com/nwnu-daizh/ 这个作业的要求在哪里 https://www.cnblogs.com/nwnu-daizh/p/11435127.html 作业学习目标 　　 1.掌握java异常处理技术； 2.了解断言的用法； 3.了解日志的用途； 4.掌握程序基础调试技巧。 第一部分：总结第七章理论知识 　　1.异常(exception)： 　　　　 1）异常对象是派生于Throwable类的一个封装了错误信息的对象实例。 　　　　2）异常具有自己的语法和特定的继承结构。 　　　　3）所有的异常都是由Throwable继承而来，但在下一层分解为两个分支：Error 和 Exception 　　　　　　1.Error类层次结构描述了Java运行时系统的内部错误和资源耗尽错误。 　　　　　　2.Exception层次结构又分为两个分支： 由程序错误导致的异常属于RuntimeException，例如：错误的类型转换；数组访问越界；访问空指针。　　另一个分支包含其他异常。 　　 　　2. 抛出(throws)异常 ：声明抛出异常在方法声明中用throws子句中来指明。 　　　　1）throws子句可以同时指明多个异常，说明该方法将不对这些异常进行处理，而是声明抛出它们。 　　　　2

Using Eclipse JDT to find all identifiers visible within a specific node

由 心不动则不痛 提交于 2021-02-07 21:55:44
问题 I'm working on a plug-in to Eclipse JDT that parses Java files and offers automatic corrections to them. I'm doing so using Eclipse's API for analyzing the AST. I'm trying to write a method that calculates the environment of a method - a list of all the identifiers that are visible within the scope of the method. Another way to look at this is the list of identifiers that can be auto-completed from a specific point in Eclipse. For example: import ... public class MyClass { private static

How to import sbt projects to Eclipse?

由 故事扮演 提交于 2021-02-07 20:16:41
问题 I want to import my sbt projects to Eclipse. While searching on the Internet I came to know there is an sbteclipse plugin for Eclipse to import sbt projects, but I don't know how to do this. I am using Eclipse Kelper and sbt 0.13 on Ubuntu 12.04 LTS. 回答1: tl;dr Use Scala IDE for Eclipse. sbteclipse is a plugin for sbt itself and aims to "create Eclipse project definitions" that in turn doesn't require installing any plugins in Eclipse. sbt is a build tool while Eclipse is an IDE. While both

问题 I have an RCP application with an existing command and handler to switch perspective programmatically. And I also have and new plugin consumed by the existing RCP application. I want this new plugin to execute the command/handler of my RCP application, what can be the possible solution for this? 回答1: You may need to define a handler for that command (not sure), but executing commands programmatically looks like this: Command command = ((ICommandService) getSite().getService(ICommandService
