这不是任何重复，我不是在询问我的字符串方程式，而是关于我想要使用的toString方法!!!!
所以我有这个代码...它所做的只是创建一个Foititis类型的对象数组，名为pinakas并具有四个属性。如果您查看名为Foititis的类，您会注意到toString方法，我想要做的就是使用toString方法在屏幕上显示某些内容（在此示例中，它已简化到array-object的onoma属性。请注意，我还想发送我想要看到的数组的某个位置（pos - ＆gt; j），在这个例子中，位置是固定的（设置为1）但在实际代码中它不会。 / p>
我尝试编译它并且我得到这两个错误，第二个可能是合理的，因为我没有以正确的方式编写代码，但是第一个呢？我再次做了同样的事情，我没有问题（创建一个对象数组）。
答案 0 :(得分：1)
您正在尝试声明一个数组，因此它应该是：
