Java Programming

Hi,
I doing password validation. Condition is character length should be 8 and it should have atleast 1 alphabet and 1 number. I have got code for doing this its working fine with 1.5 but not with 1.4.

Later i found that Scanner class is not present in 1.4. But i need to do the same functionality with 1.4. what can i do?

what can be used instead of Scanner ??

the value entered should be a string 'cos am getting the string from another file.

help needed..

Thanks in advance..
Here is my code..........

import java.util.Scanner;

	       boolean errOccurred = false; 

	       errOccurred = length <7 && length > 19;

	       if (!errOccurred)
	       {
	           
	           for (int i = 0; i < b.length ; i++ )
	           {
