# Answered Essay: You have to write a program that will take as input from the command line two pairs of coordinates: the location of the robo

You have to write a program that will take as input from the command line two pairs of coordinates: the location of the robot and the location of the gold coin. These must be whole numbers. Your program has to do the following: 1. echo the input: 2. output the number of steps (i.e., squares) that the robot has to travel horizontally and vertically to reach the gold coin: 3. specify the orientation for the robot to travel both horizontally (i.e., left or right) and vertically (i.e., up or down): and 4. calculate and output which direction travelled (horizontal or vertical) is greater 5. Implement the program using arrays and loops to let user decides when to quit the program You can assume that the grid squares are numbered like a Cartesian (X-Y) graph, with positive X going horizontally to the right and positive Y going vertically upwards. Input coordinates can be negative, but they must be whole numbers. The output distance must be positive and must be expressed in whole numbers. sample run. Below is a sample run for two cases. The command line is highlighted in bold font. uName\$ java assignment1_yourName robot is at position (8, 9) coin is at position (1, 7) robot travels 7 steps to the left robot travels 2 steps down robot travels a greater distance horizontally than vertically Do you want to continue? java assignment1_yourName 8 9 8 1 robot is at position (8, 9) coin is at position (8, 1) robot does not travel horizontally robot travels 8 steps down robot travels a greater distance vertically than horizontally Do you want to continue? source code. Your source code (i.e., assignment1_yourName.java file) but be neat and clearly commented. You must have a header comment and you should comment the end block (i.e., each)).

import java.lang.*;
class Robot
{
public static void main(String args[])
{
int rx,ry,cx,cy;
rx=Integer.parseInt(args[0]); // Accept x value for Robot
ry=Integer.parseInt(args[1]); // Accept y value for Robot
cx=Integer.parseInt(args[2]); // Accept x value for Coin
cy=Integer.parseInt(args[3]); // Accept y value for Coin
System.out.println(“robot is at position (“+rx+”,”+ry+”)”); // Display Position
System.out.println(“coin is at position (“+cx+”,”+cy+”)”); // Display Position
if(rx>cx) // Checking in Which direction Robot Should Move
System.out.println(“robot travels “+(rx-cx)+” steps to the left”);
else if(rx<cx) // Checking in Which direction Robot Should Move
System.out.println(“robot travels “+(cx-rx)+” steps to the right”);
else
System.out.println(“robot does not travel horizontally “);
if(ry>cy) // Checking in Which direction Robot Should Move
System.out.println(“robot travels “+(ry-cy)+” steps down”);
else if(ry<cy) // Checking in Which direction Robot Should Move
System.out.println(“robot travels “+(cy-ry)+” steps up”);
else
System.out.println(“robot does not travel vertically “);
if((Math.abs(rx-cx))>(Math.abs(ry-cy))) // Checking in Which direction it takes more
System.out.println(“robot travels a greater distance horizontally than vertically”);
else if((Math.abs(rx-cx))<(Math.abs(ry-cy))) // Checking in Which direction it takes more
System.out.println(“robot travels a greater distance vertically than horizontally”);
else
System.out.println(“The Robot is at its Correct Position”);
}
}
