Question

java中把若干的数字转换为整型数组，用Scanner扫描了数字输入后怎么转换为数组并输出

Answer 1

1、准备好Scanner类，List集合，int型变量一个

2、进行如下操作（只是代码片段）：

Scanner in = new Scanner(System.in);
int[] numAry = new int[10]; // 这里前提是知道要输入几个数字
for(int i=0;i<10;i++)
{
    numAry[i] = in.nextInt(); // 得到数组
}
for(int i=0;i<numAry.length;i++) // 输出数组即可
{
    if(i!=numAry.length-1)
        System.out.print(numAry[i]+",");
    else
        System.out.println(numAry[i]);
}

Answer 2

import java.util.Arrays;
import java.util.Scanner;

public class Test {
public static void main(String[] args) {
int[] arr={3,6,5,8,4,7,2};
//用scanner方法输入1，新数列变成int[] arr={1,3,6,5,8,4,7,2},并能排序输出
Scanner sc = new Scanner(System.in);
int number = sc.nextInt();
int[] arr2 = new int[arr.length + 1];
Arrays.fill(arr2,0);

System.out.println(Arrays.toString(arr2));
arr2 = Arrays.copyOf(arr,arr.length + 1);
arr2[arr.length] = number;

System.out.println(Arrays.toString(arr2));
Arrays.sort(arr2);
System.out.println(Arrays.toString(arr2));
}
}
