import java.util.Arrays;
import java.util.Scanner;
public class BaiduTest{
public static void main(String[] args) {

System.out.println("请录入数组大小");
int length = Integer.parseInt(scanner.nextLine());
int[] arr = new int[length];
System.out.println("请录入若干整数");
String string;
int count = 0;
while(count < length){
string = scanner.nextLine();
if(string.equals("end"))
break;
arr[count++] = Integer.parseInt(string);
}
scanner.close();
System.out.println(Arrays.toString(arr));
}
