Some Websites impose certain rules for passwords. Write a method that checks whether a string is a valid password. Suppose the password rule is as follows: • A password must have at least 7 characters. • A password consists of only letters and digits. • A password must contain at least one letter and at least one digit. Write a program that prompts the user to enter a password and displays "Valid Password" if the rule is followed or "Invalid Password" otherwise.

In Programming When you work with text, sometimes you need to determine if a given string starts with or ends with certain characters. You can use two string methods to solve this problem: .startswith() and .endswith()?
Write a program that reads two phrases on separate lines and outputs one of the four responses: 1) Phrase one is found within phrase two 2) Phrase two is found within phrase one 3) Both phrases match 4) No matches Hint: Use the String method indexOf(). Ex: If the input is: fire firetruck the output is: fire is found within firetruck Ex: If the input is: the green grass grows green grass the output is: green grass is found within the green grass grows Ex: If the input is: pick a card pick a card the output is: Both phrases match Ex: If the input is: apples oranges the output is: No matches(in java please)
X609: Magic Date A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false

Write a program that removes all non-alphabetic characters from the given input. Ex: If the input is: -Hello, 1 world$! the output is: Helloworld The program must define and call the following method that takes a string as a parameter and returns the string without any non- alphabetic characters. public static String removeNonAlpha (String userString)
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.
