    JAVA File类执行下面这段程序为什么会出现异常 File file=new File(args[0]); 这句是什么意思??

    import java.io.*;

    import java.util.*;

    public class FileClass {

    /**

     * @param args

     */

    public static void main(String[] args) {

    // TODO Auto-generated method stub

    try{

    File file=new File(args[0]);

    System.out.println(args[0]+"文件");

    if(file.isFile()){

    //是否为文件

    System.out.print(file.canRead()?"可读":"不可读");

    System.out.print(file.canWrite()?"可写":"不可写");

    System.out.print(file.length()+"字节");//注意不能调用数组类型 File[] 的 length（）例：File[] files=file.listFiles();不可以这么调用filess.length()

    }

    else{

    //列出所有文件及目录

    File[] files=file.listFiles();

    ArrayList<File> fileList=new ArrayList<File>();

    for(int i=0;i<files.length;i++){

    //先列出目录

    if(files[i].isDirectory()){

    //是否为目录

    //取得路径名

    System.out.println("路径"+"[  "+files[i].getPath()+"  ]");

    }

    else{

    //文件先存入fileList,待会再列出

    fileList.add(files[i]);

    }

    }

    //列出文件

    for(File f:fileList){

    System.out.println(f.toString());

    }

    System.out.println();

    }

    }

    catch(ArrayIndexOutOfBoundsException e){

    System.out.println("using:java FileDemo pathname");

    }

    }

    }

    结果：using:java FileDemo pathname

    是不是创建的对象所代表的文件没有被创建成功


     

    File file=new File(args[0]); 就是创建一个args[0]所指文件路径的文件对象。出现异常的原因是：你把args[0]作为文件路径，而你运行时又没有指定。

    Ah,here is the thing you are__________.

    A.looking at
    B.looking for
    C.taking care of
    D.needed

    答案：B
    解析：
    考查词组辨析。句意为：“看，这是你要找的东西。”look at“看”；look tor“寻找”：take care of“照顾，照看”。此外，D项中needed为过去分词，与前面are相连表示被动，而本句中并不需要用被动语态，故排除、
