Example Using Maps

import java.util.*;

public class WeightGroups {
    public static void main(String[] args) {

        // Create a map to store the frequency for each group.
        Map groupFreqData = new HashMap();

        int numArgs = args.length;
        for (int i=0; i

Running the program with the following arguments:
>java WeightGroups 74 75 93 75 93 82 61 92 10 185


gives the following output:
10:     *
60:     *
75:     ***
80:     *
90:     *
95:     **
185:    *
