    Java Selection Sorting Method Code Writing Guide and Examples Selection sorting is a simple and intuitive sorting algorithm. The idea is to select the smallest (or largest) element from the unsorted elements each time and exchange it until all elements are sorted. This article will provide a code writing guide for selection sorting, and attach specific Java sample code. Algorithm Principle The basic principle of selection sort is to divide the array to be sorted into two parts, sorted and unsorted. Each time, the smallest (or largest) element is selected from the unsorted part and placed at the end of the sorted part. Repeat the above
