1) Java storage class called Person. This class is used for a simple study that just tracks a subject's change in weight. So, this Person class keeps track of the person's first name, last name and weight.  So, the class will have the following instance variables: firstName, lastName and weight. Write the mutators for setting the instance variables.  For the first name, set the value to "NOFIRST" if a blank String is passed to the mutator for that variable.  For the last name, set the value to "NOLAST" if a blank String is passed to the mutator for that variable.  For the weight, if the mutator for weight is passed a value less than 20.0, set the value to 20.0 2) Write a constructor that sets a value for all the instance variables by calling the mutator methods 3)  Add a parameterless constructor for this class. 4) Write the accessor methods for the Person class. 5)  Write a toXML() method that will return the following String for a Person named Jane Doe who weighs 125.7 lbs.

python programing：  You are going to create a race class, and inside that class it has a list of entrants to the race.   You are going to create the daily schedule of three or so races and populate the races with the jockey/horse entries and then print out the schedule.   Create a race class that has   The name of the race as a character string, ie “RACE 1” or “RACE 2”,  The time of the race A list of entries for that race   Create a list of of 3 (or 4) of those race objects(races) for the day   For the list of entries for a particular race, make a entrant class (the building block of your entrants list) you should have   The horse name The jockey name   Now you need to   Populate the structure (ie set up three races on the schedule, add 2-3 horses entries to each race.  You can hardcode the entries if you want to, rather than getting them from the user, just to save the time of making a menu interface and whatnot. Be able to print the days schedule   So example output would be…

IN C++ Write code that: creates 3 integer values - one can be set to 0, the other two should NOT multiples of one another (for example 3 and 6, or 2 and 8) take you largest value and perform a modulus operation using the smaller (non zero) value as the divisor print out the result. create an alias for the string type call the alias "name" then create an instance of the "name" class and assign it a value using an appropriate cout statement - print out the value Please screenshot your input and output, as the format tends to get messed up. Thank you!

Language: JAVA Keep Guessing Write a program that plays a number-guessing game to guess a secret number randomly generated within the range 1 and 10. The user will get as many numbers of tries as he/she needs to guess the number. Tell the users if their guess is right or wrong and if their guess is wrong let them try to guess the number again.   You must generate the secret number using the Java Random class. When the user guesses a number he/she will have to take an input of his guessed number from the keyboard. The user will have to take as many inputs as needed to guess the correct secret-number. That means the code will keep looping as long as the guess is different from the secret number. Use a while loop to prompt the user to guess again if the guess is wrong.   Create a class named NumberGuessingGame which will contain the main method, write all your code in the main method.   Sample input and output: Suppose the random number generated is 6.   I have chosen a number between 1…
