java之数组操作（数组排序）

import java.util.Arrays;

public class ArraySort {
	public static void main(String[] args) {
		// 冒泡排序
		int[] ns = { 28, 12, 89, 73, 65, 18, 96, 50, 8, 36 };
		
		System.out.println("排序前：" + Arrays.toString(ns));
		for (int i = 0; i < ns.length-1; i++) {
			for (int j = 0; j < ns.length-i-1; j++) {
				if (ns[j] > ns[j+1]) {
					 交换ns[j]和ns[j+1]:
					int temp = ns[j];
					ns[j] = ns[j+1];
					ns[j+1] = temp;
				}
			}
		}
		System.out.println("排序后：" + Arrays.toString(ns));
		
	}
	
}

或者使用内置函数Arrays.sort()

内置函数sort:
		int[] ns = { 28, 12, 89, 73, 65, 18, 96, 50, 8, 36 };
		
		System.out.println("排序前：" + Arrays.toString(ns));
		Arrays.sort(ns);
		System.out.println("排序后：" + Arrays.toString(ns));
