int[]array={1,2,3,4,5};intlength=array.length;System.out.println("数组的长度为:"+length); 1. 2. 3. 上述代码中,我们创建了一个包含5个元素的整型数组array,然后通过array.length获取数组的长度,并将结果打印输出。运行该代码,输出结果为: 数组的长度为:5 1. 从输出结果可以看出,数组array的长度为...

public static void arraycopy(Object src, int srcPos, Object dest, int destPos, int length)。 它的根本目的就是进行数组元素的复制。即从指定源数组中复制一个数组,复制从指定的位置开始,到目标数组的指定位置结束。 将源数组src从srcPos位置开始复制到dest数组中,复制长度为length,数据从dest的destPos位置开始...
