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)).
