将此用于您的第一个示例程序，我在System.arraycopy处更改了参数
public class DynamicArrayOfInt{private int[] data;public DynamicArrayOfInt(){ data = new int[1];}public int get(int position){ if (position >= data.length) return 0; else return data[position]; }public void put(int position, int value){ if (position >= data.length) { int newSize = 2 * data.length; if (position >= newSize) newSize = 2 * position; int[] newData = new int[newSize]; System.arraycopy(data, 0, newData, 0, data.length); data = newData; System.out.println("Size of dynamic array increased to " + newSize); } data[position] = value;}}
