① assumes that the element at the first index is the minimum, and compares it with other values. If the element at the current index is greater than the value at some other index, it assumes that the value at the other index is the minimum, and finally finds the index where the minimum is located.

② swaps the value at the first index and the index where the minimum value is located

Select sort API design class name Selection constructor Selection (): create Selection object member method

1.public static void sort (Comparable [] a): sorts the elements in an array

2.private static boolean greater (Comparable v comparison w): judge whether v is greater than w

3.private static void exchange (Comparable [] a drawing int iline int j): swap the values at index I and index j in the an array
