Update Bresenham's line (JAVA) method such that you can scale the line before drawing it. Normally, you pass two points and a Graphics' object to draw line using Bresenham's algorithm. Now you'll add scaling factors in arguments for scaling as shown below. public void drawBresenhamline(Point p1, Point p2, double Sx, double Sy, Graphics g) { I/write your code here } Note:If you use scaling method, then also write Scale method in solution.
The obvious next step is to name the stars and planets using random numbers. Names usually follow certain rules rather than being made up of random strings of characters. Choose a set of real-world names (for example, from J.R.R. Tolkien's world) and create a set of rules for them to follow. Create and implement a method for generating new names based on a set of rules and random numbers.
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…

A maze is a two dimensional array of chars. Walls are represented as '#'s and ' ' are empty squares. The maze entrance is always in the first row, second column (and will always be an empty square). There will be zero or more exits along the outside perimeter. To be considered an exit, it must be reachable from the entrance. The entrance is not an exit.Here are some example mazes:mazeA7 9# # ###### # # ## # # #### # ## ##### ## ########## RequirementsWrite a MazeSolver class in Java.

What is a HashMap? What is its purpose and how do you use it? Answer these questions in writing, and use the Java library documentation of Map and HashMap for your responses. Note that you will find it hard to understand everything, as the documentation for these classes is not very good. We will discuss the details later in this chapter, but see what you can find out on your own before reading on.
Write a method that takes two string parameters, and tells whether the first is a substring of the second. You can't use framework methods that do this for you, such as indexOf(). In other words, you have to write the loops yourself. But, you can use the primitive methods such as charAt(). Also analyze the program's performance and state the big-O complexity of your method. Provide a screenshot of the code working.
