Rename:
First we rename a file.
// file location
File oldFile = new File("C:\\Users\\radiate\\Desktop\\OldFolder\\villain.jpg"); // source file location
String oldFileName = oldFile.getName();
// rename the villain.jpg file to darklord.jpg
String rename = oldFileName.replace(oldFileName, "darklord.jpg");
System.out.println("old file name: " + oldFileName +"\n"+"rename file name : " +rename);
Output:
old file name: villain.jpg
rename file name : darklord.jpg
Copy:
Now we move the rename file into another location.
File newFileLocation = new File("C:\\Users\\radiate\\Desktop\\NewFolder"); // destination location
try {
FileInputStream inputOldFile = new FileInputStream(oldFile);
FileOutputStream outputNewFile = new FileOutputStream(newFileLocation.getAbsolutePath()+"\\"+rename);
// this is for copy the file into new location with new name
byte[] buffer = new byte[1024];
int filelength;
while((filelength= inputOldFile.read(buffer))>0){
outputNewFile.write(buffer, 0, filelength);
}
inputOldFile.close();
outputNewFile.close(); // end copy
System.out.println("Successful Rename and move");
} catch (IOException e) {
e.printStackTrace();
}
Output:
old file name: villain.jpg
rename file name : darklord.jpg
Successful Rename and move
