I need help with Java code. I'm not sure how to start...

Assume that a password is valid if and only if it contains at least one letter, at least one digit, and at least five characters in t otal. Write a boolean method named isValidPassword. The method should receive a String and determine whether the String is a valid password. Examples: .isValidPassword ("557s3") should be true • isValidPassword ("55r17s3") should be true isValidPassword ("55753") should be false should be false isValidPassword("eftyh") isValidPassword("5783") should be false Tip: you may want to use the charAt method of the String class and the isDigit and istetter methods of the Character class.
