I can then define a new array called z2, which is just z1 with one added to every single element of the array. 然后我可以定义一个名为z2的新数组,它只是z1,数组的每个元素都添加了一个。 We can now look at these two arrays to see what their contents are. 现在我们可以看看这两个数组,...
但有个可以改变大小的数组为ArrayList,即可以定义一个ArrayList数组,然后用add(element)方法往里添加元素即可,还可add(index,element)往指定下标处添加元素;例子如下...但这儿会有一个陷阱盲区,在把array转化为list的过程中,使用的asList()方法会返回一个final的,固定长度的ArrayList类,并不是java.util.ArrayList,...
