Question

When I try to save a file with the file name that already exists, I need to prompt the user to rename the file in order to save. What is the better way to prompt the user rename the File f the same File exists in the directory?I need to implement this via the same dialog box I use to save the file.

File exportFile = new File(FilePath + "\\"+ FileName);
boolean exists = exportFile.exists();  

if (!exists) {  

    System.out.println("File does not exists");  
    // TODO code here             
}
else{  

    System.out.println( "File exists.");
    // TODO code here                                       
}

The code is to be implemented in the //TODO part. How can I do this?

Answer 1

while(exists) { \\Prompt the user to enter another name & change "exists" status correspondingly}

            while(exists) 
        {
         String temp=dis.readLine();
         exists = (FilePath + "\\"+ temp).exists();
         if(!exists) {exportFile = new File(FilePath + "\\"+ temp); break;}

          }  

where dis is a DataInputStream object. Good luck.
