一些array类

package com.haoran.method;

import java.util.Arrays;

public class Demo04 {
    public static void main(String[] args) {
        int a[]={1,2232,544,11,14,43,2};
        System.out.println(a);
        //打印数组
        System.out.println(Arrays.toString(a));
        //排序打印数组
        System.out.println(Arrays.toString(a));
        //填充
        Arrays.fill(a,0);
        System.out.println(Arrays.toString(a));
        //指定元素的填充
        Arrays.fill(a,2,4,99);
        System.out.println(Arrays.toString(a));

    }
