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.

Concept explainers

Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

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…
in the United States, telephone numbers consist of a three digit area code followed by a seven digit local number. Suppose neither the first digit of an area code nor the first digit of a local number can be a zero but that all other choices are acceptable. do not use commas when you write your number. For example enter 3356789 NOT 3,456,789
Write a console program, that will calculate the pocket money saved over a period, with one cent at the start of account setup, will double every day. For example, if the opening balance is one cent the first day, it will be two cents the second day, and continues to double each day. The console program you will write, should ask the user for the number of days, and display a table showing what the saving was for each day, and then show the total savings at the end of the period. The output should be displayed in a dollar amount, not the number of cents.
