I m使用新工作计算机,该电脑有旧的 s子, Java1.3.1,我希望看到,我是否能够做某些类别的家务劳动。 我从我们的教授那里获得这一档案,并用他的机器进行班级工作,在我管理时,我正在发现编辑错误。 我对 Java帮助档案进行在线检查,并像收集一样,在1.3.1之前得到了支持,因此我无法确定我为什么会发现这些错误。 我的守则是:

import java.io.*; 
import java.util.*; 

public class WriteFile
{ 

    public static void main(String[] args) 
    { 
        if(args.length == 0) {
            args = new String[] { ".." }; 
        }
        List<String> nextDir = new ArrayList<String>();
        nextDir.add(args[0]); 
        try 
        { 

                while(nextDir.size() > 0) 
                { 
                    File pathName = new File(nextDir.get(0)); 
                    String[] fileNames = pathName.list(); 

                    for(int i = 0; i < fileNames.length; i++) 
                    { 
                        File f = new File(pathName.getPath(), fileNames[i]); 
                            if (f.isDirectory()) 
                            { 
                                System.out.println(f.getCanonicalPath()); 
                        nextDir.add(f.getPath()); 
                        } 
                        } 
                nextDir.remove(0); 
                } 
        } 
            catch(IOException e) 
            { 
                e.printStackTrace(); 
            } 
    } 
} 

Errors: ( or ] on line 12 which to me doesn t look like an error. Then a lot of cannot resolve symbol for List, String, nextDir on line 12, etc.

我认为,这要么是多余的,要么是对我的工作组合的错误。 感谢。

最佳回答

一般课程只得到java 1.5+的支持。

定期名单

List nextDir = new ArrayList();

希望这样做

问题回答

在 Java5之前,我不相信通用(即List<String>)。
