3. Having a secure password is a very important practice, when much of our information is stored online. Write a program that validates a new password, following these rules: The password must be at least 8 characters long. The password must have at least one uppercase and one lowercase letter. The password must have at least one digit. Write a program that asks for a password, then asks again to confirm it. If the passwords don't match or the rules are not fulfilled, prompt again. Your program should include a function that checks whether a password is valid.

Write a program to find out the grade of a student based on the marks obtained in three subjects. The grade is calculated as: If average is 80 or greater than 80, grade is ‘A’. If average is less than 80 and greater then 50, grade is ‘B’. If average is less than 50 and greater then 33, grade is ‘C’. If average is less than 33, grade is ‘F’

In various applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0. Write a program that prompts the user to enter any number of values into a double array, and then calculates and displays the mean and standard deviations of these numbers using the following formulas: (z - mean) z+z3+ *** +zn deviation = mean = n-1 Required Methods You must write your program so that the following methods are defined/implemented and used (called): • /* Compute the deviation of double values */ public static double deviation (double[] x) • /* Compute the mean of an array of double values */ public static double mean (double[] x) Sample Run (user input…
