将整数数组添加到ArrayList <int[]>

Question

I have an arraylist

ArrayList<int[]> strokeLines = new ArrayList<int[]>();

and a function which runs everytime the mouse is clicked which adds the current mouse position and the previous mouse position to this arraylist

strokeLines.add({mouseX, mouseY, pmouseX, pmouseY});

I had this code working earlier but I lost everything I wrote in the past hour, and when I rewrote this part it wouldn't work. How can I add the array {mouseX, mouseY, pmouseX, pmouseY} to the end of the arraylist?

Answer 1

您需要创建一个新的int[] ：

strokeLines.add(new int[]{mouseX, mouseY, pmouseX, pmouseY});

Answer 2

简单地-

strokeLines.add(new int[]{mouseX, mouseY, pmouseX, pmouseY});
