代码如下：已经考虑到输入错误的情况，输入的不是整数或者是字母需要重新输入。
import java.util.Scanner;
public class Test {
public static void main(String [] args){
int[] arr = new int[10];
for (int i = 0; i < arr.length; i++) {
System.out.print("请输入第"+(i+1) + "个数字：");
arr[i] = input();
}
System.out.println("输入完毕。

for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + "");
}
System.out.println("
倒序输出：");
for (int i = arr.length-1; i >= 0; i--) {
System.out.print(arr[i] + "");
}
}

try{

}
