Javaでファイルを別のディレクトリに移動する方法
以下の2つの例では、ファイル ”
C:¥¥folderA¥¥Afile.txt
“をあるディレクトリから別のディレクトリ ”
C:\\ folderB \\ Afile.txt
“に移動します。
1. File.renameTo()
package com.mkyong.file; import java.io.File; public class MoveFileExample { public static void main(String[]args) { try{ File afile =new File("C:\\folderA\\Afile.txt"); if(afile.renameTo(new File("C:\\folderB\\" + afile.getName()))){ System.out.println("File is moved successful!"); }else{ System.out.println("File is failed to move!"); } }catch(Exception e){ e.printStackTrace(); } } }
2.コピーと削除
package com.mkyong.file; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; public class MoveFileExample { public static void main(String[]args) { InputStream inStream = null; OutputStream outStream = null; try{ File afile =new File("C:\\folderA\\Afile.txt"); File bfile =new File("C:\\folderB\\Afile.txt"); inStream = new FileInputStream(afile); outStream = new FileOutputStream(bfile); byte[]buffer = new byte[1024]; int length; //copy the file content in bytes while ((length = inStream.read(buffer)) > 0){ outStream.write(buffer, 0, length); } inStream.close(); outStream.close(); //delete the original file afile.delete(); System.out.println("File is copied successful!"); }catch(IOException e){ e.printStackTrace(); } } }
