我想在实例级别初始化数组,但我无法在这里初始化代码

public class Arrays {

    /** Creates a new instance of Arrays */

        int []arr2=new int[2];
        arr2[0]=20;//error at compile time
        arr2[1]=30;//error 


    public Arrays() {        }
    public static void main(String []args)
    {
        System.out.println("Element at 0th position is "+arr2[0]);
        System.out.println("Element at 1th position is "+arr2[1]);
    }


}
