Expert Solution & Answer
Chapter 1, Problem 3P
Explanation of Solution
Purpose of the given code:
The given code is to product the two numbers and displays the result.
Syntax error:
An error which is occurred on the source code of a program is referred as “syntax error”; because the computer programs are strictly follows the syntax rules, if the code fails to prove its language syntax format then the compiler will throws an error.
Error in the given code:
n1=keyboard.nextInt();
n2=keyboard.nextInt();
The variables “n1” and “n2” are not declared in the given statement. Hence, it throws the syntax error.
Corrected code:
//Import required package
import java.util...

Art.java
In this part you will create a program Art.java that produces a recursive drawing of the design attached in the picture.
Requirements
Art.java must take one (1) integer command-line argument n that controls the depth of recursion.
Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.)
You may not change the size of the drawing window (but you may change the scale). Do not add sound.
Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions.
Optionally, you may use the Transform2D library you implemented in Part 1. You may also define additional geometric transforms in Art.java, such as sheer, reflect across the x- or y- axis, or rotate about an arbitrary point (as opposed to the origin).
Your program must be organized into at least three separate functions, including main(). All functions except main() must be private.

Instructions
The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly.
An example of the program is shown below:
Enter name Juan Hello, Juan!
Task 1: The DebugThree3 class compiles without error.
Task 2: The getName() method accepts user input for a name and returns the name value as a String.
Task 3: The displayGreeting() method displays a personalized greeting.
Task 4: The DebugThree3 program accepts user input and displays the correct output.

For each move, you have a choice: move the pawn down a single space, or move the pawn down one space and right one space. That is, if the pawn is at position (i,j), you can move the pawn to (i+1,j) or (i+1, j+1). Ask the user for the size of a chessboard, n (integer). Find the number of different paths starting from (0,0) that the pawn could take to reach each position on the chess board. For example, there are two different paths the pawn can take to reach (2,1). Look at the diagrams below to convince yourself of this. You can see the four paths that you can take by move 2. Start -> Move 1 -> Move 2 (0,0) -> (1,0) -> (2,1) (0,0) -> (1,0) -> (2,0) (0,0) -> (1,1) -> (2,1) (0,0) -> (1,1) -> (2,2) Print the board with the number of ways to reach each square labeled as shown below.
