Java數組的複製方法__Java

Java複製資料的三種方式：

1、System.arraycopy()：

public static void main(String[] args){    Object[] array = { "1", "2" };    Object[] arrayNew = new Object[array.length];    System.arraycopy(array, 0, arrayNew, 0, array.length);    for (int i = 0; i < array.length; i++)    {        System.out.print(arrayNew[i] + " ");    }}

2、Arrays.copyof()：

public static void main(String[] args){    Object[] array = { "1", "2" };    Object[] arrayNew = Arrays.copyOf(array, array.length);    for (int i = 0; i < array.length; i++)    {        System.out.print(arrayNew[i] + " ");    }}

3、Arrays.copyOfRange()：

public static void main(String[] args){    Object[] array = { "1", "2" };    Object[] arrayNew = Arrays.copyOfRange(array, 0, array.length);    for (int i = 0; i < array.length; i++)    {        System.out.print(arrayNew[i] + " ");    }}
