Java初学实现动态插入数组

package hello;import java.util.Scanner;public class DoubleArray2 { public static void main(String []args){ int[] num = {10,12,23,45,90}; Scanner sc = new Scanner(System.in); while(true) { System.out.print("请输入你需要插入的数："); int in = sc.nextInt(); if(in<=num[0]){ int []num1 = new int[num.length+1]; for(int j=0;j=1;q--){ num[q] = num[q-1]; } num[0] = in; } else if(in>=num[num.length-1]){ int []num1 = new int[num.length+1]; for(int j=0;jin){ int []num1 = new int[num.length+1]; for(int j=0;ji+1;q--){ num[q] = num[q-1]; } num[i+1] = in; } } } System.out.print("当前数组为："); for(int i=0;i
