Java初始化整数并将其添加到一行中的列表中

Question

A tiny annoyance I have in my code right now - these two lines of code:

int i = 1;
listOfIntegers.add(i);

I would really like these to be one line but I can't for the life of me find anything like "new int[] {1}" or similar. Is this possible?

Answer 1

Yes, it is, and it is as easy as possible :)

listOfIntegers.add(1);

PS : For primitive data types you dont have to create "instances" of them, they are instances itself.
