Java定义一个类输入一个整数， 然后输入整数个数据到数组中

public class MyClass {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("请输入整数：");
int n = scanner.nextInt();
int[] arr = new int[n];
System.out.print("请输入" + n + "个数据：");
for (int i = 0; i < n; i++) {
arr[i] = scanner.nextInt();
}
System.out.println("输入的数组为：" + Arrays.toString(arr));
}
}
