Java：使用FOR循环将元素添加到arraylist，其中元素名称的数量越来越多 [英] Java: Add elements to arraylist with FOR loop where element name has increasing number

问题描述

 回答answer1;我有一个数组列表，我想通过for循环添加元素。 
答案answer2; 
答案答案3; 
 
 ArrayList< Answer> answers = new ArrayList（3）; 
 
 for（int i = 0; i <3; i ++）
 {
 answers.add（// HOWTO：Add each answer？）; 
 
 
 
 $ b编辑：如果我有，我们可以说50个答案元素？ 
解决方案
你不能这样做，你可能做这样的事情： / p> 
 
 
  List< Answer> answers = new ArrayList< Answer>（）; 
 for（int i = 0; i <4; i ++）{
 Answer temp = new Answer（）; 
 //在这里执行所需的初始化
 answers.add（temp）; 
} 
  
 
I have an arraylist where I want to add elements via a for loop.
Answer answer1;
Answer answer2;
Answer answer3;

ArrayList<Answer> answers = new ArrayList(3);

for (int i=0;i<3;i++)
{
    answers.add(//HOWTO: Add each of the answers?);
}
EDIT: How would this go if I have, let's say 50 Answer elements?
解决方案
You can't do it the way you're trying to... can you perhaps do something like this:
List<Answer> answers = new ArrayList<Answer>();
for(int i=0; i < 4; i++){
  Answer temp = new Answer();
  //do whatever initialization you need here
  answers.add(temp);
}
