包路径：java.lang.OutOfMemoryError
类名称：OutOfMemoryError

OutOfMemoryError介绍

[英]Thrown when a request for memory is made that can not be satisfied using the available platform resources. Such a request may be made by both the running application or by an internal function of the VM.
[中]当使用可用平台资源无法满足内存请求时引发。这样的请求可以由正在运行的应用程序或VM的内部功能发出。

private void expandArray() {

    if (newCapacity < 0) {

    }

    Object[] newArray = new Object[newCapacity];
    System.arraycopy(array, 0, newArray, 0, array.length);

    array = newArray;
