Hi All,
I want/need a coding example of getting this
data type below from a file named "t.tmp"
ArrayList<String> dimensions = new ArrayList<String>();
and a
ArrayList<String> clr = new ArrayList<String>();
These data types were written to a file before,
now I can't get the data out of the file.
How were they written into the file? If you cannot answer that, could
you describe the file as it would look in a text or hex editor? How you
read data from a file is heavily influenced by what the format of the
file is.

Hi Joshua,
Here is what was written to the
file using these named ArrayList
ArrayList<String> dimensions = new ArrayList<String>();
ArrayList<String> colorpxl = new ArrayList<String>();
......
With this :
String respName = "ColorPixlData.txt";
System.out.println("File Saved as "+ respName);
try {
FileOutputStream fout = new FileOutputStream(respName);
ObjectOutputStream out = new ObjectOutputStream(fout);
out.writeObject(dimensions);
out.writeObject(colorpxl);
out.flush();
out.close();
}catch (IOException e) {e.printStackTrace();}
}
Here is the start of the contents of this file.
Google may not even print it in this form .....
