JavaDay05.练习2.有一个已经排好序的数组,现在输入一个数字,按照规律将它插入到数组中

import java.util.Arrays;

public class Homework2 {

    public static void main(String[] args) {
        int[] arr = {3, 7, 0, 3, 1, 9};
        int[] newArr = insertElementIntoArr(arr, 5);
        System.out.println(Arrays.toString(newArr));
    }

    
    public static int[] insertElementIntoArr(int[] arr, int num) {
        int[] newArr = Arrays.copyOf(arr,arr.length+1);
        newArr[newArr.length - 1] = num;
        Arrays.sort(newArr);
        return newArr;
    }
}
