Three ways to sort Ava array elements

In Java, when using array to sort the function, there are four kinds of methods: fast sorting method, bubbling method, choosing Sort method, inserting sort method.
The fast sorting method mainly uses a method arrays.sort () implementation in arrays.
The bubbling method uses a traversal array to compare the minimum or maximum values by a continuous comparison.
The selection sort method is to use the first data of the array as the maximum or minimum value, and then to output an ordered array by comparing loops.
