從文件[]文件目錄

Question

我有代碼的一個問題：

public class Files { 

    public static void main(String[] args) throws IOException { 
     // filter files AAA.txt and BBB.txt from another's 
     File f = new File("d:\\dir"); // current directory 
     File f1 = new File("d:\\dir1\\"); 


     FilenameFilter textFilter = new FilenameFilter() { 
      public boolean accept(File dir, String name) { 

       if (name.startsWith("A") && name.endsWith(".TXT")) { 
        //System.out.println(name); 
        return true; 
       } 
       else if (name.startsWith("B") && name.endsWith(".TXT")) { 
        //System.out.println(name); 
        return true; 
       } 
       else { 
        //System.out.println(name); 
        return false; 
       } 
      } 
     }; 

     File[] files = f.listFiles(textFilter); 
     for (File file : files) { 
      if (file.getName().startsWith("A")) { 
       //here save file to d:\\folder1\\ 
      } 
     } 
    } 
} 

我如何保存例如與特定名稱的文件AAA.txt到文件夾1和BBB.txt到文件夾2.感謝任何例子

從Files類從Java 7：
使用move(Path source, Path target, CopyOption... options)

import static java.nio.file.StandardCopyOption.*; 
import java.nio.file.FileSystem; 
import java.nio.file.Path; 
import java.nio.file.Files; 
... 
for (File file : files) {  
    if (file.getName().startsWith("A")) { 
    //here save file to d:\\folder1\\ 
    // convert file to Path object use toPath() method. 
    Path targetFilePath = FileSystems.getDefault().getPath("d:\\folder1\\").resolve(file.getFileName()) 
    Files.move(file.toPath(), targetFilePath , REPLACE_EXISTING); 
    } 
}
