- Create a class with [3][3] dimension and the java programshould display the magic square. Kindly explain each statement that you will use.Create a python program in Physics and Materials Science. In physics, chemistry, and materials science, percolation refers to the movement and filtering of fluids through porous materials. (Wikipedia.org). Consider a simplified model below. Imagine, this is a filter or maybe some layers of stones such that when a certain amount of fluid is put on top, it will reach the bottom only if there is a direct passage. In this case, the blue squares serve as the porous materials or the holes where fluid may pass. Your task is to simulate this simple percolation by representing them in a 2-dimensional array. The input would be in a string, while the output would either be yes or no to indicate whether the fluid can pass through the filter or not. Examples: Input: “1,0,0,0,0;0,1,0,0,0;0,1,0,0,0;0,0,1,0,0;0,0,0,1,0”Output: Yes Input: “1,0,0;0,1,0;0,0,0;0,0,1”Output: No Input: “0,0,0,1,0;0,1,0,0,0;0,1,0,0,0;0,0,1,0,0;0,0,0,1,0”Output: No Note: It should also work with these two inputs:1. “1” ->…Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segment

- THIS IS MEANT TO BE IN JAVA. What we've learned so far is variables, loops, and we just started learning some array today. The assignment is to get an integer from input, and output that integer squared, ending with newline. But i've been given some instructions that are kind of confusing to me. Please explain why and please show what the end result is. Here are some extra things i've been told to do with the small amount of code i've already written... Type 2 in the input box, then run the program so I can note that the answer is 4 Type 3 in the input box instead, run, and note the output is 6. Change the output statement to output a newline: System.out.println(userNumSquared);. Type 2 in the input box Change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before). This is what I have so far... import java.util.Scanner; public class NumSquared {public static void main(String[] args) {Scanner scnr = new…You are working as a software developer on NASA's Mars Explorer robotic rover project. You need to implement some code to compute the surface area of the 3D, tube-shaped part shown below: a cylinder of radius r and height h (in units centimeters) with a hollowed-out center also in the shape of a cylinder with radius n and height h (also in cm). Both the outside and the inside of the tube will need to be coated in a thin layer of gold, which is why we need to know its surface area. Write code that will compute and print the total surface area of the shape. n esc r Examples: Inputs r = 10, n = 8.5, h = 22.5 r = 9.25, n = 6.8, h r = 4.15, n = 3.9, h = 11.7 = 12.16 X h Output Value 2789.7342763877364 1473.347264273195 604.4267185874082 2 3 80 F3 000 DO F4 ✓0 F5 完成时间:18:42 PNEUE MacBook Air F6 F7 DII F8 tv 8 F9 F10 FPlease use java to complete this program
- I need help with the content on the image below. The Code is Java.We need to use java program. I need to solve this question quickly.Please help me solve this with java .... just the HangMan HangMan instruction class : • HangMan is a game in which a player tries to guess a word based on a given hint. For example, if the given hint is “movie”, then the player must guess a movie name. If the given hint is a “country”, then the player must guess a country name, and so on.• The game starts by showing a message on the screen that shows the hint and all letters in the word but obscured as dashes (-). Then, the game will allow the player to guess 5 letters. If the player gives a letter that actually exists in the word, then this letter will be revealed. Afterwards, the game will ask the player to give the answer. If the given answer is correct, then the game will show a message that the player has won 5 points. Otherwise, the game will show a message that the player has lost. Below is one possible game scenario, in which the word is “iron man”, and the hint is “movie”. Note that the text in green color is the…
