The Question

Write a program called Q1.java. It should prompt for and then read from standard input (the keyboard) a sequence of whitespace separated strings. It should output the words one per line, sorted in descending order, and without duplicates (i.e. the 2nd or further instances of the same word are not shown). Before outputting the words, the program should write a short dashed line ("----------") to visually separate output from input - see the sample output below.

The output should conform to that in the sample run of a correct program shown below. Note that, in the sample run, the % sign is not part of the program output.
