Question
Here is the description of the program I need to do. It is in JavaProblem Description:
Some Websites impose certain rules for passwords. Write a method that checks whether a string is a valid password. Suppose the password rule is as follows:
• A password must have at least eight characters.
• A password consists of only letters and digits.
• A password must contain at least two digits.
Write a program that prompts the user to enter a password and displays "valid password" if the rule is followed or "invalid password" otherwise.
Sample 1
Enter a string for password: wewew43x
valid password
Sample 2
Enter a string for password: 343a
invalid password
Analysis:
(Describe the purpose, processing, input and output in your own words.)
Design:
(Describe the major steps for solving the problem.)
Testing: (Describe how you test this program)

please rate - thanks
import java.util.Scanner;
public class ValidPassword
{
public static void main (String[] args)
{String word;
boolean a,b,c,d,e,f;
Scanner input = new Scanner(System.in);
System.out.print("Enter a string for password: ");
word=input.next();
if (len(word) && letter(word) && number(word))
System.out.println("valid password");
else
System.out.println("invalid password");
}
public static boolean len(String s)
{int i;
if(s.length()>=8)
return true;
return false;
}
public static boolean letter(String s)
{int i;
for(i=0;i<s.length();i++)
if (!Character.isLetter(s.charAt(i))&&!Character.isDigit(s.charAt(i)))
return false;
return true;
}
public static boolean number(String s)
{int i,n=0;
for(i=0;i<s.length();i++)
if (Character.isDigit(s.charAt(i)))
n++;
if(n<2)
return false;
return true;
}
