(Check password) Some websites impose certain rules for passwords. Write a
method that checks whether a string is a valid password. Suppose the password
rules are as follows:
A password must have at least eight characters.
A password consists of only letters and digits.
A password must contain at least two digits.
Write a program that prompts the user to enter a password and displays Valid
Password if the rules are followed or Invalid Password otherwise.
(Number of days in a year) Write a method that returns the number of days in a year using the following header:
public static int numberOfDaysInAYear(int year)Write a test program that displays the number of days in year from 2000 to 2020.
2) Two integers are said to be relatively prime if their greatest common divisor (GCD) is one. For
example 12 and 13 are relatively prime, but 12 and 14 are not.
a. Write a method called relativelyPrime that accepts two integer parameters A and B. The
method should output if A, and B are relatively prime or nat.
Use the following method header:
public static void relativelyPrime(int A, int B)
b. Write a test program (main) to test the method by asking the user to input two positive
integers X and Y. Then the program will call the method relativelyPrime to output if X and Y are
relatively prime or not.
Sample Run 1:
Enter Two positive integers X and Y: 12 13
12 and 13 are relatively prime
Sample Run 2:
Enter Two positive integers X and Y: 12 14
12 and 14 are not relatively prime

- (Computer-Assisted Instruction) The use of computers in education is referred to as computer-assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use a Random object to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate method should be used to generate each new question. This method should be called once when the application begins execution and each time the user answers the question correctly.arrow_forward(In Java) In the game Clacker, the numbers 1 through 12 are initially displayed. The player throws two dice and may cover the number representing the total or the two numbers on the dice. For example, for a throw of 3 and 5, the player may cover the 3 and the 5 or just the 8. Play continues until all the numbers are covered. The goal is to cover all numbers in the fewest rolls. Create a Clacker application that displays 12 buttons numbered 1 through 12. Each of these buttons can be clicked to ‘cover’ it. A covered button displays nothing. Another button labelled Roll can be clicked to roll the dice. Include labels to display the appropriate die images for each roll. Another label displays the number of rolls taken. A New Game button can be clicked to clear the labels and uncover the buttons for a new game.arrow_forward(CLO3) Read the following description and answer the following questions about it: Problem Description: A car dealership allows customer to purchase their new cars with different options.

- (Game: ATM machine) Use the Account class created in our previous Lab Exercise to simulate an ATM machine. Create ten accounts in an array with id 0, 1, . . ., 9, and initial balance $100. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not stop.arrow_forward(Using Java in eclipse) write a method which takes two integers a and b as inputs, determines which of the two integers is larger, and returns half of the value of the larger integer example output: inputs are 7 and 4. half of the max is 3.5arrow_forward(Java in Eclipse) Write code that finds the sum of two matrices.

- (java programing) I don't want it in handwriting. Define a student class. A student has the following attributes: Firstname: the name of the student lastname: the name of the family Gender: which can be male or female status: which can be equal to freshman, sophomore, junior, and senior gpa: The average which value is between 0.0 to 4.0 Then define the following methods for the student class. • The show_myself: method will simply print all the attribute variables when called upon the object. This method has no input arguments. • The study_time: method will increment the gpa of the student according to the following formula: ` gpa = gpa + log(study_time)`. The only input argument of this method is the variable study_time. • In addition make sure that the gpa variable never exceeds 4.0 even if the student studies for a very long time. • Any necessary methods that is required for such class.arrow_forward(java programing) Define a student class.
