Java Collection - 如何从另一个数组复制一个数组

public class Main {
  public static void main(String[] args) {
    int[] intArray = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 };

    int[] arrayCopy = new int[intArray.length];

    System.arraycopy(intArray, 0, arrayCopy, 0, intArray.length);

    for (int i = 0; i < arrayCopy.length; i++)
      System.out.println(arrayCopy[i]);
  }
}
