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 total. Write a boolean method named isValidPassword. The method should receive a String and determine whether the Stringis a valid password. Examples:.isValidPassword ("557s3") should be true• isValidPassword ("55r17s3") should be trueisValidPassword ("55753") should be falseshould be falseisValidPassword("eftyh")isValidPassword("5783") should be falseTip: you may want to use the charAt method of the String class and the isDigit and istetter methods of the Characterclass.

Question

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.
