In java Write a program that takes the name of a grayscale image file as a command line argument and uses StdDraw to plot a histogram of the frequency of occurance of each of the 256 grayscale intensities. Show me how to complete the TODO i set up. Here is a link to draw https://introcs.cs.princeton.edu/java/stdlib/ And I also posted Luminance.java that converts to grayscale.
