Java冒泡排序、选择排序代码实现（初学者）

import java.util.Arrays;

public class rank {
	public static void main(String[] args) {
		// 冒泡排序
		int[] pao = { 3, 5, 8, 1, 2, 6, 4, 9, 7 };
		System.out.println("冒泡排序：");
		for (int j = 0; j < pao.length - 1; j++) {
			for (int i = 0; i < pao.length - 1 - j; i++) {
				int temp;
				if (pao[i] > pao[i + 1]) {
					temp = pao[i];
					pao[i] = pao[i + 1];
					pao[i + 1] = temp;
				}
			}
			System.out.println(Arrays.toString(pao));
		}

		System.out.println("--------------------------");

		// 选择排序
		int[] xuanze = { 5, 8, 100, 26, 32, 16, 54, 69, 7 };
		int s;
		System.out.println("选择排序：");
		for (int i = 0; i < xuanze.length; i++) {
			int mid = i;
			s = xuanze[i];
			for (int j = i; j < xuanze.length; j++) {
				if (xuanze[j] < s) {
					s = xuanze[j];
					mid = j;
				}
			}
			xuanze[mid] = xuanze[i];
			xuanze[i] = s;
			System.out.println(Arrays.toString(xuanze));
		}

		System.out.println("--------------------------");
