处理：内存不足错误

我正在使用Processing . 这是我的全部素描：

import guicomponents.*;

PImage backgroundImage;

void setup() {      
  size(911, 715); 
  backgroundImage = loadImage("Floorplan.png");
}
void draw() {
  background(backgroundImage);
  GImageButton[] buttons = {
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10),
    new GImageButton(this, null, "wm.png", 1, 10, 10)
  };
}

（这只是一个演示来说明我遇到的问题 . ）如果运行的时间足够长，将生成一个 OutOfMemoryError ：

An OutOfMemoryError means that your code is either using up too much memory
because of a bug (e.g. creating an array that's too large, or unintentionally
loading thousands of images), or that your sketch may need more memory to run.
If your sketch uses a lot of memory (for instance if it loads a lot of data files)
you can increase the memory available to your sketch using the Preferences window.
Exception in thread "Image Fetcher 2" java.lang.OutOfMemoryError: Java heap space

为什么会发生这种情况？当数组在 draw() 末尾超出范围时，内存是否会收集垃圾？

我试图让按钮抽搐时遇到这个问题 . 我找不到改变其位置的方法，所以我只是在我想要的新位置创建了一个新的位置 . 有一个更好的方法吗？
