Those years, the Java 7-1_1 that we learned together

/**

* 7-1

* The program that writes the character interface, accepts a number of positive integers entered by the user,

*-1 indicates the end of the input.

* Sort the input data in descending order using the sort algorithm

* and print the results after each scan

* The runtime uses the following different data series to observe its execution results

* 1. There is only one data in the sequence

* 2. Duplicate data in a sequence

* 3. The data entered in the sequence is sorted in ascending order

* 4. The data entered in the sequence is sorted in descending order
