Given the following method that checks for a valid 5-digit number, what do we need to fix?
Public static boolean isValid(String s)
{
If (s != null && s.length() == 5)
{
Int i = 0;
Boolean b = Character.isDigit(s.charAt(i)) &&
Character.isDigit &&
Character.isDigit) &&
Character.isDigit) &&
Character.isLetter);
}
Else
{
Return false;
}
}
A) Change the parameter variable type to integer
