Question: (Code must be in java language)
Assuming that you have the functions “drawPolygon(int[] x, int[] y, int n)” for drawing polygon, “drawRectangle(int x, int y, int width, int height)” for drawing rectangle and “drawCircle(int xc, intyc, int radius)” for drawing circle; draw the given shape.
Where: R(300,250), T1(325,275), T2(475,275), T3(400,400), P1(285,250), P2(225,275), P3(200,450), P4(285, 300), Q1(515,250), Q2(575,275), Q3(600,450), Q4(515,300)//Look attached image here
Note: No need to write the definition of the methods, there are no marks for definition. Only use method calls to create the shape as shown in Figure 1.
in java: Write a program that reads the following information and prints a payroll statement:
Employee’s name (e.g., Smith)
Number of hours worked in a week (e.g., 10)
Hourly pay rate (e.g., 9.75)
Federal tax withholding rate (e.g., 20%)
State tax withholding rate (e.g., 9%)
Your program must use proper formatting for the output either by using the printf command or String.format
java
You must print the number declared double x; on the screen. With which of the following options do you know that a number in the range -9999.99999 to 9999.99999 is printed with exactly 4 decimals and that all numbers in the number are displayed?
Choose an alternative:

- The body mass index, BMI, is a measure used to determine if a person is overweight or not. We can calculate BMI from the weight of the person (in pounds) and the height (in inches) of the person.The formula for calculating BMI is:BMI = (weightInPounds * 703) divided by (heightInInches squared)In this problem, you will develop a Java program as a BMI calculator, that reads the user’s weight in pounds and height in inches, then calculates and displays the user’s body mass index BMI. Also, display the following information {from the US Department of Health} so the user can evaluate his/her BMI:BMI values:Underweight: less than 18.5Normal: between 18.5 and 24.9Overweight: between 25 and 29.9Obese: 30 or greaterarrow_forwardTHIS IS MEANT TO BE IN JAVA So far we've learned variables, branches, loops, and some array.

They want to befaster than everyone else in their class, so they decided to write a C code to help them find wordswith a click of a button. Little did they know, everyone in class decided to do this question. You are required to implement search2D function. void search2D(char word[], int wordSize, const int Size, char grid[Size][Size]); search2D receives the word to look for char word[], the size of the word int wordSize, sizeof the grid const int Size and the puzzle grid char grid[Size][Size]. The word size can bebetween 2 and 23. You are NOT required to check for the validity of the word size.search2D should look for the first letter in the word row by row. If it finds the first letter of the wordin the puzzle, it should look for the remaining of the word in the 8 directions from the south and goesclockwise, i.e. south, south-west, west, north-west, north, north-east, east and lastly…arrow_forward
- what are the difference betweenpassing an argument by pass by value and pass by refference?arrow_forwardAssume you are working as a developer in a bank, and you have been asked to develop a programto validate credit card numbers. Assume also that each credit card number consists of 8 digits. Thefollowing method is used to verify that the credit is valid or not: - Starting from the rightmost digit, form the sum of every other digit. For instance, if thecredit card number is 43589795, then you form the sum 5 + 7 + 8 + 3 = 23. - Double each of the digits that were not included in the preceding step. Add all digits of theresulting numbers. Considering for example the above credit card number 43589795,doubling the digits starting from the next-to-last one, yields 18 18 10 8. Adding all digitsin these values yields 1 + 8 + 1 + 8 + 1 + 0 + 8 = 27 - Add the sum of the two preceding steps. If the last digit of the resulting sum is 0, the creditcard number is valid; otherwise, it is invalid. In our case, 23 + 27 = 50, so the number isvalid.
