java - 将数组作为对象的参数传递问题

Question

我想将数组作为对象的参数传递，但我是一种堆栈。 这就是我的问题。

public class Publisher {

    public static void main(String args[]) {
        String teachers[] = {"Jyothi", "Jyostna", "Sumathi"};
        Publisher2 p1 = new Publisher2(teachers[1],20);       //The problem is here, I can't specify 
     //index of array (I can put onlu teachers without index[1])so toString method is returning address of object instead of the name
        System.out.println(p1);
    }
}

class Publisher2 {

    String[] teachers;
    int y;

    public Publisher2(String[] teachers, int y) {
        this.teachers = teachers;
        this.y = y;
    }

    @Override
    public String toString() {
        return "Publisher2{" + "teachers=" + teachers + ", y=" + y + '}';
    }
}

Answer 1

teachers[1] 是数组中的第二个元素。数组本身就是teachers。就像，

Publisher2 p1 = new Publisher2(teachers, 20);
