I need assistance with this java code. Please put the code into something I can copy Thanks! Shape2DWrite the following four classes to practice using an abstract class and polymorphism. Submit all four classes.Shape2D classFor this class, include just an abstract method name get2DArea () that returns a double.Rectangle2D classMake this class inherit from the shape2D class. Have it store a length and a width as fields. Provide a constructor that takes two double arguments and uses them to set the fields. Note, the area of a rectangle is thelength times the width.Circle2D classAlso make this class inherit from the shape2D class. Have it store a radius as a field. Provide a constructor that takes a double argument and uses it to set the field. Note, the area of a circle is PI times it's radiustimes it's radius.Shape2DDriver classHave this class provide a method named displayArea () that takes an object from just any of the above three classes (you can't use an object type parameter). Have the method display (not return) the area of theobject, rounded to one decimal place.

NOTE : Create 4 classes as named Below: Shape2D.java // creating abstract classpublic abstract class…

Hello! Need help with this. Need to create a JavaFX Project that displays the respective colored circle and rectangle. for program 2, I need to code a drawing of an emoji as shown in the image. Both need to be under one project. Thank you!
in 250 or more words, explain when you would use SELINUX and also talk about the controls that you would set with it
Using DrawingPanel.java (from chapter 3G), draw a grid for filling in a 4 x 4 square of cell containing integers. For this part of the assignment the values are not important, but you are welcome to use the values shown in the magic square from below. Note that the values in any horizontal row, vertical column or main diagonals add up to 34, in addition to various sub-squares in the larger square also add up to the same value. Requirements: The magic square should be centered in the panel The values in each of the cells should be centered in that cell (both horizontally and vertically). You can assume the values will be <= 99 (i.e., at most 2 digits). For this part of the assignment, you can hard-code the values; you will store them in a 2-dimensional array (from chapter 7) when implementing Part B of the assignment. The title "CSC 142 Magic Square" is centered horizontally in the panel and at y = 50 You are free to choose the colors, fonts, font sizes and effects. This is what I used…
Hi, thank you! Is there a way to do it without numpy?
The class I'm taking is assembly programming. I am completely stuck. I keep getting multiple errors! help! Can you please write out program so I can compare where I went wrong.

Final Project/Capstone Idea I choose a tracker for my work hours as a final project ? If I will use Java what GUIs would allow you to create. Include any ideas of what they have in common? What about them to get me excited? Share all these thoughts because that'll help me to build my project?
Java... Comments will greatly help me. Thank you!
