在Codenameone中使用分割方法时出错 [英] Error using split method in Codenameone
问题描述
我创建了一个新的Codenameone项目。它包含以下代码:
I have created a new Codenameone project. It contains the following code:
String values = "one, two, tree";
String[] v = values.split(",");
当我构建项目时,出现此错误:
When I build the project, I got this error:
location: variable definition of type String
error: cannot find symbol
String[] v = values.split(",");
symbol: method split(String)
但是,如果我使用示例项目 MapsDemo并使用split方法,则一切正常。
However, if I take the sample project "MapsDemo" and use the split method, everything is ok.
可以做什么
谢谢。
推荐答案
代号一个支持Java 5和 String.split()
的子集不存在。在所有平台上更改VM实现代码要比在一个包空间的代号中添加一个可移植库要困难得多。使所有边缘情况都100%兼容也变得更加困难,并且使可执行文件更大(即使您不使用它,也要为String.split付费!)。
Codename One supports a subset of Java 5 and String.split()
isn't there. Its much harder to change the VM implementation code across all platforms than just add a portable library in the codename one package space. Its also harder to make all the edge cases 100% compatible and it makes the executable larger (you pay for String.split even if you don't use it!).
我们有 StringUtils
和 StringTokenizer
,在 cn1lib 部分。
