Write a Java class called PyramidVolume that reads from the user 2 integers represent area of the base (B) and the height of a pyramid (h). Then calculates and prints the volume of this pyramid (rounded to 1 decimal place) according to the following formula: volume = (1/3) h B Note: If the user enters any non-positive value (i.e. less than or equal to zero), an error message should be displayed and nothing should be calculated. Paragraph - B I && 4

Java code please 4. Jackpot! by CodeChum Admin Did you know that in lotteries, a 3-digit number with the same numbers in all digits like 777 will hit the jackpot in a casino? In the same manner, let's make a program that will test if a certain 3-digit number hits a jackpot or not by identifying if all the digits of a given number is the same as the second inputted number. If it is, print "Jackpot!"; else, print "Nah". Let's try this out now! Input A line containing two integers separated by a space. 777·7 Output A line containing a string. Jackpot!
Write a JAVA program that converts a number entered in Roman numerals to decimal. Your program should consist of a class named Roman, and an object of type Roman should do the following:a) Store the number as a Roman numeral.b) Convert and store the number into decimal.c) Print the number as a Roman numeral or decimal number as requested by the userThe decimal values of the Roman numerals are:• M 1000• D 500• C 100• L 50• X 10• V 5• I 1d) Your class must contain the method romanToDecimal to convert a Roman numeral into its equivalent decimal number. Use the class name “LastnameClasscodeFinal2”.
Write a Java class called Power. This class defines a method called power() which takes as parameters a double called base as well as an int called exponent, and returns a double representing the value of base raised to the power exponent. The exponent is a non-negative integer value, and that base and exponent are not both 0. You MUST write the computation yourself; in other words, you MUST NOT use the Math.pow() method. Repeat the operation often.
2. Write a java program which will input an integer value from the user (Use Scanner class). Your program will have mathOper() method in addition to the main() method.The main() method will be responsible for:a. extracting the 1's digit (ones), the 10's digit (tens), and any digits larger than the 10's digit. For instance, if the input is 3562, the 1's digit would be 2, the 10's digit would be 6, and the remaining digits would be 35.b. call the mathOper() method with these 3 values,c. print the results to the screen.The mathOper() method will make the following calculations:a. Multiply the 1's digit by 7, subtract the result by 2 and then divide that by 5.b. Add 3.5 to the 10's digit, multiply the result by 4.3 and then divide that by 2.c. Subtract 5 from the remaining digits, multiply the result by 3, find the remainder after dividing that by 7, and then add 6 to the remainder value.d. Add the 3 values obtained from ‘a’, ‘b’, and ‘c’ operations.e. Return the final value.Sample output…
Create a Java class that implements the following: You are driving a little too fast, and a police officer stops you. Write code to compute the result, encoded as an int value: 0=no ticket, 1=small ticket, 2=big ticket. If speed is 60 or less, the result is 0. If speed is between 61 and 80 inclusive, the result is 1. If speed is 81 or more, the result is 2. Unless it is your birthday -- on that day, your speed can be 5 higher in all cases. Declare appropriate variables. Display a short message informing the user about the purpose of this class. Provide appropriate instructions to the user for input values Display the result based on the resulting int value. Example: Speed: 75 Birthday: false Output: Small Ticket
In Java, Write a program that converts a number entered in Roman numerals to decimal. Your program should onsist of a class, sa Roma. An object of type Roman should do the following: 1. Store te number as a Roman numeral. 2. Convert and store the number into deciaml. 3. Print the number as a Roman numeral or decimal number as requested by the user. The decimal values of the Roam numerals are: M 1000 D 500 C 100 L 50 X 10 V 5 I 1 Your class must contain the method romanToDecimal tp cpnvert a Roman numeral omtp its equivalent decomal number. I wanted to compare my oldk code to see if iI had my program right from a former class. Thank

A rational number is the quotient of two integers - the numerator and denominator. The denominator cannot be zero. Two rational numbers can be added, subtracted, multiplied and divided. Write a java classRational for a rational number with the following specs: • A constructor that gets two integers (make sure the denominator is not 0).• The numerator and denominator should be private.• Getters: public int getNumerator() and public int getDenominator()• Setters: public void setNumerator(int n) and public void setDenominator(int d)• Public methods public Rational add(Rational r1), public Rational subtract(Rationalr1), public Rational multiply(Rational r1) and public Rational divide(Rational r1).• Printer function: public void print(). The number should be printed in the format n/d (numerator, forward-slash, denominator).
Write a complete Java program that performs the following tasks: Ask the user to enter the last two digits of his/her student ID. Break the number into two digits using arithmetic operators, then store the first and second digits in integer variables named digit1 and digit2 Find and print the following: The product of digit1 and digit2. The sum of digit1 and digit2 The average of digit1 and digit2 The maximum of the two numbers; digit1 digit2 using a method from the class Math. Note: The class name of your Java program must be your first name. Your answer should have the code as text as well as the screenshot of the program output (using your own student ID) as a part of your answer. Otherwise, zero marks will be awarded.
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…
