是否可以使用for循环在Java中创建n个对象? [英] Is it possible to create n number of objects in java using a for loop?

问题描述

例如；我正在使用此类:

For example; i'm using this class:

Point originOne = new Point(x, y);

如果我要创建N个点(originTwo，originThree ... originN)； 我可以使用像这样的for循环吗?

If i want to create a N number of points (originTwo,originThree...originN); can I do it using a for loop like :

for(int i=0;i<n-1;i++){

   }  

如果可能的话；我如何给他们起不同的名字?

If it's possible; how do i give them different names?

推荐答案

您可以将它们放入数组中.

You could put them into an array.

Point[] origin = new Point[n];
for (int i = 0; i < n; i++) {
    origin[i] = new Point(x, y);
}

在这些情况下，他们都将使用相同的x和y.

They'd all be using the same x and y under those conditions.

如果您有一个x和y的数组，则可以这样操作:

If you had an array of x and y you could do it like this:

Point[] origin = new Point[n];
for (int i = 0; i < n; i++) {
    origin[i] = new Point(x[i], y[i]);
}

如果您不喜欢数组，则可以使用列表:

If you don't like arrays, you could use a list:

List<Point> origin = new ArrayList<>();
for (int i = 0; i < n; i++) {
    origin.add(Point(x[i], y[i]));
}

您将其称呼为

origin.get(i)
