The code is compiled but gives errors (

package com.company; public class BoolVector { int size; // размер вектора int[] arr = new int[size]; // элементы вектора BoolVector(int size) { for(int i=0;i<size;i++) { System.out.print("Введите число"); arr[i]=10; } } } public class Main { public static void main(String[] args) { BoolVector A = new BoolVector(2); for (int i = 0; i < A.size; i++) { System.out.print(A.arr[i]); } return; } }

Here is what the compiler produces:

Insert the number

     BoolVector(int size) { arr = new int[size]; for(int i=0;i<size;i++) { System.out.print("Введите число"); arr[i]=10; } } }

    The size of the array is zero. It needs to be created after the transfer size.
