第14周作业

题目：编写一个应用程序，输入一个目录和一个文件类型，显示该目录下符合该类型的所有文件。之后，将这些文件中的某一个文件剪切到另外一个目录中。

package com.huang;
import java.util.*;
import java.io.*;
class FileAccept implements FilenameFilter{
    String type;
    FileAccept(String type){
        this.type = type;
    }
    public boolean accept(File Fname, String name) {
        return name.endsWith(type);
    }
    
}
public class Main {
    public static void main(String[] args) {
        System.out.println("请输入目录:");
        Scanner q = new Scanner(System.in); 
        String s = q.next();
        File Fname = new File(s);                        
        System.out.println("请输入文件类型");
        Scanner q1 = new Scanner(System.in); 
        String p = q1.next();
        FileAccept shu = new FileAccept(p);
        String fileList[] = Fname.list(shu);       
        System.out.println(s+"目录下有"+fileList.length+"个文件");
        for(int i =0;i<fileList.length;i++) {
            System.out.println(fileList[i]);
        }     
        
        
        System.out.println("请输入要剪切的文件");
        Scanner q2 = new Scanner(System.in);        
        String G = q2.next();    
        String f = s+"\"+G;       
        File Fname1 = new File(f);
        String FilePath = "D:\黄晓天\abc"+"\"+G;    
        try(BufferedReader close1 = new BufferedReader(new FileReader(f));
            BufferedWriter writer = new BufferedWriter(new FileWriter(FilePath));    
            ) {        
            String line = null;//线程
            while((line=close1.readLine())!=null) {
                System.out.println(line);
                writer.write(line);
            }
        } catch (FileNotFoundException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        System.out.println("提示：被剪切的"+G+"文件"+"已经剪切完毕。");
        Fname1.delete();                
    }
}
