Java 格式错误的字符（需要引号，得到I）~正在处理

我希望有人能帮我解决我的问题。我试图做一个简单的可视化展示，展示足球队在2012年国际足联排名中是如何上升还是下降的。为此，我创建了17个图像并将其加载到我的草图中，我希望根据按钮事件移动这些图像。下面是我的代码：

//Setting up the images that will go into the sketch

PImage img1;
PImage img2;
PImage img3;
PImage img4;
PImage img5;
PImage img6;
PImage img7;
PImage img8;
PImage img9;
PImage img10;
PImage img11;
PImage img12;
PImage img13;
PImage img14;
PImage img15;
PImage img16;
PImage img17;

//loading the images from the file
void setup() {
  size(600, 1100)
  img1 = loadImage('Click.png');
  img2 = loadImage('Team_xxxxx.png');
  img3 = loadImage('Team_xxxxxx.png');
  img4 = loadImage('Team_xxxxxx.png');
  img5 = loadImage('Team_xxxxxxx.png');
  img6 = loadImage('Team_xxxxx.png');
  img7 = loadImage('Team_xxxxxx.png');
  img8 = loadImage('Team_xxxxxxx.png');
  img9 = loadImage('Team_xxxxxx.png');
  img10 = loadImage('Team_xxxxxx.png');
  img11 = loadImage('Team_xxxxx.png');
  img12 = loadImage('Team_xxxxx.png');
  img13 = loadImage('Team_xxxxx.png');
  img14 = loadImage('Team_xxxxxx.png');
  img15 = loadImage('Team_xxxxx.png');
  img16 = loadImage('Team_xxxxx.png');
  img17 = loadImage('Team_xxxxxx.png');
}

//Drawing the images into the sketch
void draw() {
  image(img1, 400, 100);
  image(img2, 100, 250);
  image(img3, 100, 300);
  image(img4, 100, 350);
  image(img5, 100, 400);
  image(img6, 100, 450);
  image(img7, 100, 500);
  image(img8, 100, 550);
  image(img9, 100, 600);
  image(img10, 100, 650);
  image(img11, 100, 700);
  image(img12, 100, 750);
  image(img13, 100, 800);
  image(img14, 100, 850);
  image(img15, 100, 900);
  image(img16, 100, 950);
  image(img17, 100, 1000);
}

我一直收到这样的错误消息：格式错误的字符（需要引号，得到I）。下面是控制台中的输出：

 processing.app.SketchException: Badly formed character constant (expecting quote, got l)

我正在运行OS X的Macbook Pro上使用Processing 2.0B7。错误可能来自

img1 = loadImage('Click.png');

特别是

'Cl

位。字符常量由一个单引号（

“

）、一些字符和另一个单引号（

”

）组成。
您拥有的是一个单引号（

”

），一个

C

，然后是一个

l

由于您似乎希望使用字符串常量，请尝试使用双引号：

img1 = loadImage("Click.png");
