JAVA 有一个已经按升序排好序的数组。现输入一个数，要求按原来的规律将它插入数组中。

 package cn.bdqn.demo02;

import java.util.Scanner;

public class Lianxi2 {

	public static void main(String[] args) {
			int a[] = {1,2,3,4,5,6,7,8,9,10};
			Scanner sc = new Scanner(System.in);
			System.out.println("輸入你加入的數：");
			int num = sc.nextInt();
			int index = 0;
			int newA[]=new int [a.length+1];
			for(int i=0;ia[i]){
					index = i+1;
				}
			}
			for(int i =newA.length-1;i>index;i--){
				newA[i]=newA[i-1];
			}
			newA[index]=num;
			for(int i=0;i
