数组升序和数组填充array

import java.util.Arrays;

public class Demo06 {
    public static void main(String[] args) {
        int[] a = {1,2,5555,674,22};

        //System.out.println(a);

        //打印数组元素
        //System.out.println(Arrays.toString(a));

        Arrays.sort(a);//数组进行排序：升序
        System.out.println(Arrays.toString(a));

        Arrays.fill(a,2,4,0);//数组填充：2-4范围（下标不包括4）
        System.out.println(Arrays.toString(a));

        //printArray(a);
    }
    public static void printArray(int[] a){
        for (int i = 0;i < a.length;i++){
            if (i==0){
                System.out.print("[");
            }
            if (i==a.length-1){
                System.out.print(a[i]+"]");
            }else{
                System.out.print(a[i]+", ");
            }
        }
