Java System.arraycopy()方法详解

//src源数组  srcPos复制起始位置  dest目的数组  destPos放置起始位置  length复制长度

System.arraycopy(Object src, int srcPos, Object dest, int destPos, int length);

实例:

String[] one = new String[]{"aa", "bb", "cc", "dd"};

String[] two = new String[]{"11", "22"};

System.arraycopy(one, 1, two, 1, 1);

two = {"11", "bb"};
