I need a basic and simple Java code for this exercise:

(Check password) Some websites impose certain rules for passwords. Write a method that checks whether a string is a valid password. Suppose the password rules are as follows:

A password must have at least eight characters. A character is alpha or digit.

A password consists of only letters and digits. No other symbols.

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 rules are followed or Invalid Password otherwise. For example, abcdef12 is legal, 12345678 is legal, $abcde12 is not legal, abcdefgh is not legal.
