数组升降序以及填充

package array;

import java.util.Arrays;

public class ArrayDemo7 {
    public static void main(String[] args) {
        int[]  a = {1,2,3,4455,6677,4};
        System.out.println(a);
        //打印数组元素Arrays.toString
        System.out.println(Arrays.toString(a));
        //排序:升序
        Arrays.sort(a);
        System.out.println(Arrays.toString(a));
        //数组填充
//        Arrays.fill(a,888);
//        System.out.println(Arrays.toString(a));
        //2-4之间填充
        Arrays.fill(a,2,4,0);
        System.out.println(Arrays.toString(a));
    }
}
