Write a Java method to check whether a string is a valid password.

Password rules:
A password must have at least ten characters.
A password consists of only letters and digits.
A password must contain at least two digits.

There are at least SIX functions/methods as the following:

1. menu() – to print the password’s rules.

2. getString() – to get the password from the user.

3. isPassword() – to check either the password is valid based on the given rules. 4

. getChar() - to get the input from the user, either ‘y’ or ‘n’.

5. isLetter() – to check the password to be a letter from ‘A’ to ‘Z’.

6. isNumric() – to check the password to be a number from ‘0’ to ‘9’.

fprintf("1.A password must have at least eight characters.\n") fprintf("2.A password consists of only letters and digits.\n") fprintf("3.A password must contain at least two digits .\n") password=input("Input a password (You are agreeing to the above Terms and conditions.):",'s');

len= length (password);

valid=true;

if len<8 valid=false; else digit_count =0; for i= 1:len ch=password (i);. if ch>='0'&&ch<='9' digit_count=digit_count+

1; elseif(ch<'a' II ch>'z') &&. (ch<'A' II ch>'z') valid=false; end end if digit_count<2 valid =false; end end

if valid printf("password is valid :%S\n", password). else. printf("password is invalid:%S\n", password) end

Write a function to check whether string s1 is a substring of string s2. The function returns the first index in s2 if there is a match. Otherwise, return -1. For example, the function should return 2 if s1 is "to" and s2 is "October". If s1 is "andy" and s2 is "candy", then the function should return 1. The function prototype is as follows: int indexOf(const char *s1, const char *s2).
