I have tried to use this code but I keep getting error " SoftwareSerial does not have a type"

You have not included the SoftwareSerial library in your program
I'm not sure what you mean by software serial :-S
Sorry

Look at the fourth line.
Edit - and the error you're getting...
Okay, I can see the 4th line says "SoftwareSerial mySerial(2, 3);"
I'm very new to this code writing and I just took the example from the Tutorial - How do I fix this

By the way, the authors of that Tutorial must have mangled the code when they uploaded it.

int getFingerprintIDez();
So the code is useless then :-(.
Add the line
#include <SoftwareSerial.h>at the start of the program
Thanks, got pass the error message.
Now I have this one
Arduino: 1.6.5 (Windows 8.1), Board: "Arduino/Genuino Uno"
sketch_sep03a:14: error: 'Adafruit_Fingerprint' does not name a type
sketch_sep03a.ino: In function 'void setup()':

sketch_sep03a:217: error: expected '}' at end of input
'Adafruit_Fingerprint' does not name a type
.
Ive put this line in
#include <Adafruit_Fingerprint.h>
And the error has gone but not sure if its correct as I get this error messages now

That code is appalling to read. There should only be one terminating semicolon on one line, and the only thing that may follow it is a comment.
I know it's not your code, but if you put each statement on its own line, remove unnecessary blank lines, then do auto-format (Tools menu), and repost your code (using code tags!) we might have a fighting chance!
Please post your whole program as it is now using code tags. Select the text of the code in the message editor and click the code icon (</>) above the editor window. Formatting the code (Ctrl/T) in the IDE and removing the superfluous blank lines before copying here would be helpful too.
finger.begin(57600); // set the data rate for the sensor serial port }
Move the } to the next line away from the comment.
EDIT:
I could swear there was a program listing in the previous message...
Better, but it would be even better with the extraneous blank lines removed and each { and } on its own line.
In the meantime, you have
void loop() // run over and over again
{
getFingerprintID();
The getFingerprintID() function returns a value but you are not assigning it to a variable so the compiler thinks that you are defining a function here.
I was just making some changes before the posts

Now you have nothing in the loop() function. I assume that the closing brace above should not be there.
I have found this code but when uploading I get this error message

What error? All I see is a memory usage report from a successful compilation.
Ive sorted it - was on the wrong com port.
