如何在Java中将ArrayList转换为另一个ArrayList [英] how convert an ArrayList another ArrayList in java

问题描述

嗨 我有一个这样的ArrayList

[100, 101, 110, 011, 1111, 1110, 010, 00, 00]

我想将ArrayList转换为类似的内容

[1,0,0,1,0,1,1,1,0,0,1,1,1,1,1,1,1,1,1,0,0,1,0,0,0,0,0]

请帮助我
thx

解决方案

我认为您需要将第一个列表从元素0迭代到最后，将每个返回的项目拆分成其组成部分，并将每个部分添加到第二个部分数组.

hi i have an ArrayList like this

[100, 101, 110, 011, 1111, 1110, 010, 00, 00]

i want to convert that ArrayList to something like this

[1,0,0,1,0,1,1,1,0,0,1,1,1,1,1,1,1,1,1,0,0,1,0,0,0,0,0]

please help me
thx

解决方案

I would think you need to iterate the first list from element 0 to the end, splitting each returned item into its constituent parts and adding each part to the second array.
