1. Write a program that separately prompts the user for a first name and last name and outputs a string containing the following information, in order: a. First letter of the user's name. b. First five letters of the user's last name. c. A random two-digit integer. You must construct the desired string ensuring all characters are lowercase; output the identification string accordingly. Assume the last name contains at least 5 characters. You must use the Random (java.util.Random) class to generate random numbers. As an example, input of Chris Alvin may result in calvin15.

- USE THE PROGRAM CODE BELOW TO CODE 1. COMMAND LINE ARGS CODE IN JAVA 1. Command Line Args Modify problem # 1 from Lab 8 to accept the values for the key as command line arguments. Your program may assume the arguments given at the command line are integers. If there are no arguments, print a message. If there is at least one argument, compute and print the average of the arguments. Note that you will need to use the parseInt method of the Integer class to extract integer values from the strings that are passed in. If any non-integer values are passed in, your program will produce an error, which is unavoidable at this point. Test your program in NetBeans using the data for problem # 1 Lab 8 as command line arguments. import java.util.Scanner;import java.text.NumberFormat; public class Quizzes{ //---------------------------------------------- // Read in the number of questions followed by // the key, then read in each student's answers // and calculate the number….3.2: Basic class use. Print person1's kids, call the incNumKids() method, and print again, outputting text as below. End each line with a newline.Sample output for below program with input 3:Kids: 3 New baby, kids now: 4Three variables, x, y, and z, supposedly hold strings of digits, suitable for converting to integers. Write a code that converts these variables into integers and print sum of the three integers. However, if any variable has a value that cannot be converted to an integer, print out, the string "bad value(s) in:" followed by the names of the variables that have bad values (separated by spaces, in alphabetically ascending order). For example, if the values of x, y, and z were respectively "3", "9", "2" then the number 14 would be printed; but if the values were "abc", "15", "boo" then the output would be: bad value(s) in: x z

A phrase is a palindrome if, after converting all uppercase letters into lowercase letters and removing all non-alphanumeric characters, it reads the same forward and backward. Alphanumeric characters include letters and numbers. Given a string s, return true if it is a palindrome, or false otherwise. Example 1: Input: s = "A man, a plan, a canal: Panama" Output: true Explanation: "amanaplanacanalpanama" is a palindrome. Example 2: Input: s = "race a car" Output: false Explanation: "raceacar" is not a palindrome..Write a code for craps game. Craps is a dice game in which the players make wagerson the outcome of the roll, or a series of rolls, of a pair of dice.The rules of the dice game craps are as follows:You roll two dice. Each die has six faces, which contain one, two, three, four, five and six spots,respectively. After the dice have come to rest, the sum of the spots on the two upward faces iscalculated. If the sum is 7 or 11 on the first throw, you win and play is over. If the sum is 2, 3or 12 on the first throw you lose and play is over. If the sum is 4, 5, 6, 8, 9 or 10 on the firstthrow, that sum becomes your “point.” To win, you must continue rolling the dice until you“make your point” (i.e., roll that same point value). You lose by rolling a 7 before making yourpoint(in python)
