- Create a class called Mather with a main method.Create an int width = 7. Create an int height = 6.Create the output below. Use Java arithmetic, do not just type in the numbers (hint, make use ofslide 2-59 and use parenthesis for math if you need to).While not required, try to use String constants instead of raw text for output (ie, “The area is: “).You can do this assignment iteratively. First, create that output. Then, extract each text messageinto a String, making sure the program still works correctly.Output:The area is: 42Width plus height is: 13Width modulus height is: 1Width divided by height is: 1Modify the Lab 6 java applet that produces a Bulls Eye with six concentric circles usingtwo colors as shown below. The applet should include a method that creates anddisplays a filled circle. The for loop should be modified to use the method. (See pg. 376,Programming Project 11, Savitch).The fillCircle method can be placed above or below the paint method and should bedefined using the following:private void fillCircle (Graphics canvas, int X, int Y, int diameter, Color color){canvas.setColor(color);canvas.fillOval(X, Y, diameter, diameter);}The program should continue to use Named Constants to establish and maintain the xand y settings for the circles and the amount to change the diameter for each circle.Use a for loop to control the drawing of each of the 6 circles. Within the loop, increasethe x, y settings; reduce the diameter for the new circle; and alternate the colors whencalling the drawCircle method. Test your code using the AppletViewer.Sample using AppletViewwrite program in java Create a Java Project With Your name as “EemanAsadProjectQNo1”, add a class to this Project, Class name should be Your Name with Your Reg No as “YourName18-arid-2860” Add a Method to Accept names and marks of nstudents from user, enter the value of nfrom Userb. Ensure that valid data is entered. If user enters an invalid data, then appropriate message should be displayed using Message Dialog Box e.g. ‘Name cannot be a number’ or ‘Marks must be an integer value’ Add another Method, to Display this data in descending order according to marks such that name of student having maximum marks should come at the top and the name of student having minimum marks should come at the bottom.
- Please help me complete this Java class and keep the code simple. You will complete the class called NameWork. The input() method has already been started foryou. Finish it following the directions contained in the comments.In addition, the class will have the following methods: monogram( ) : this method will return a String containing the full set of initials for theperson's name. DO NOT OBTAIN THE PERSON'S NAME AGAIN. Use the existingvariable name. You do not need to redeclare the variable, as it is already declared inyour class.The full set of initials means you build the String by obtaining the first letter of eachname. The person may have entered only their first and last name, their last name mayconsist of two names, or they may have entered a middle name. Think about whatseparates the first, last, and middle names for someone -- that will help you find the firstletter of each name. salute( ) : this method will return a String with the person's first initial (first letter…Implement the main method below in a class called Grade. The program should read integer points (use the Scanner class) and print the grade (“A”, “B”, “C”, “D”, or “F”) based on the final score associated with a student. Grades are classified as follows: Number of Points Final Grade Greater than or equal to 90 A Between 80 (inclusive) and 90 (exclusive) B Between 70 (inclusive) and 80 (exclusive) C Between 60 (inclusive) and 70 (exclusive) D Less than 60 F Restrictions/Assumptions Use the message “Enter final score” to prompt the user to enter the number of points. Use the Scanner class to read the number of points, i.e., Scanner sc = new Scanner(System.in); Use System.out.println(...) to print the final grade. Assume that the user correctly enters an integer score. Start with this code: import java.util.Scanner; public class Grade { public static void main(String[] args) { For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac)Please provide JAVA source code for following assignment.

- I need help with this. Thanks in advance It might not be reasonable to expect users to type long entries such as “oil change” accurately. Implement the CarCareChoice2 class so that as long as the user enters the first three characters of a service, the choice is considered valid. An example of the program is shown below: Enter selection:oil changetire rotationbattery checkbrake inspectionbatry checkbatry check price is $15 import java.util.*; public class CarCareChoice2 { // Modify the code below public static void main (String[] args) { Scanner input = new Scanner(System.in); boolean isMatch = false; String[] items = { "oil change", "tire rotation", "battery check", "brake inspection"}; int[] prices = {25, 22, 15, 5}; int x; int matchIndex = 0; String menu = "Enter selection:"; for(x = 0; x < items.length; ++x) menu += "\n " + items[x]; System.out.println(menu); String selection =…Create a new Java project and make sure "Create project from template" is UNCHECKED). Use a meaningful name such as M4-PA-PatternMaker. Then create a new Java class called PatternMaker in the src folder. Add a main method to this class. The program should follow the guidelines below. The program prompts the user for two input values: An integer value between 2 and 9 (inclusive) for the number of characters in each row to be printed An integer value between 2 and 9 (inclusive) for the number of rows to be printed The number of rows must be smaller than the number of characters per row. If this is violated, repeat 1 and 2 until the user provides the right integers. The first line of the contains a number of `#` and ends with 1. The number of `#` decreases by 1 per line and the number of digits increases by 1 to maintain the same total number of characters per line. The program must use nested for loops to print the pattern. Below are some sample runs. === Pattern Maker === Please…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…

System.out.println(cal.getTimeInMillis());C. System.out.println(cal.getMillis());D. System.out.println(cal.getMillisTime());E. System.out.println(cal.getTimeMillis()); Part 2 - 4.

A. cal.set(Calendar.MONTH, 1);B. cal.set(Calendar.MONTH, 2);C. cal.set(Calendar.MONTH, 3);D. cal.set(Calendar.MONTH, Feb);E. cal.set(Calendar.MONTH, February);In this exercise you will write a program to compute the distance between any two geo locations. In this program you will ask the user for four numbers. USE JAVA starting latitude starting longitude ending latitude ending longitude Then, using the GeoLocation class and our earlier example as a reference, compute the distance in miles between the two locations. A sample program run should match exactly as below: Enter the latitude of the starting location: 48.8567 Enter the longitude of the starting location: 2.3508 Enter the latitude of the ending location: 51.5072 Enter the longitude of the ending location: 0.1275 The distance is 208.08639358288565 miles.
