Java 二维数组中的错误ArrayOutOfBoundException

我在第110行得到错误

ArrayOutOfBoundException:15

：

尝试运行此代码时：

导入TUIO.*；
TuioProcessing tuioClient；
int cols=15，rows=10；
布尔[][]状态=新的布尔[cols][rows]；
字符串[][]坐标=新字符串[cols][rows]；
int videoScale=50；
//这些是使用的一些辅助变量
//创建可伸缩的图形反馈
int x，y，i，j，k，l；
浮动光标_size=15；
浮动对象大小=60；
浮动台_尺寸=760；
浮动比例系数=1；

布尔详细值=false；//打印控制台调试消息
布尔回调=true；//仅在回调后更新
无效设置（）{

noCursor（）；

font=createFont（“Arial”，18）；
比例系数=高度/桌子尺寸；
//最后，我们创建一个TuioProcessing客户机的实例

tuioClient=新的TuioProcessing（this）；
}
作废提款（）{
//开始列的循环
对于（k=0；k如果（（mouseX>=x&&mouseX=y&&mouseY您试图在以下循环之外使用变量
k
和
l
-

  for ( k = 0; k < cols; k++) {
    // Begin loop for rows
    for ( l = 0; l < rows; l++) {

或者你不想在那里结束
k
和
l
循环（我在这篇文章开头提到的那些循环）？你没有注释掉那部分吗？
变量
k
的值在这个for循环的末尾是15

for ( k = 0; k < cols; k++) {
// Begin loop for rows
     for ( l = 0; l < rows; l++) {

       // Scaling up to draw a rectangle at (x,y)
       int x = k*videoScale;
       int y = l*videoScale;

       fill(255);
       stroke(0);


        for (int i = 0; i < cols; i++) {
          for (int j = 0; j < rows; j++) { 

            coordinates[i][j] = String.valueOf((char)(i+65)) +      String.valueOf(j).toUpperCase();

          }
        }
        rect(x,y,videoScale,videoScale); 
     }
   }

这就是为什么你会有例外

希望这有帮助。
请在这里显示第110行中的内容。draw（）中的前两个循环结束于函数的末尾-这就是您要做的吗？（第三个和第四个循环在第二个循环内）@kiruwka第110行是我后面引用的行
for ( k = 0; k < cols; k++) {
// Begin loop for rows
     for ( l = 0; l < rows; l++) {

       // Scaling up to draw a rectangle at (x,y)
       int x = k*videoScale;
       int y = l*videoScale;

       fill(255);
       stroke(0);


        for (int i = 0; i < cols; i++) {
          for (int j = 0; j < rows; j++) { 

            coordinates[i][j] = String.valueOf((char)(i+65)) +      String.valueOf(j).toUpperCase();

          }
        }
        rect(x,y,videoScale,videoScale); 
     }
   }

System.out.println(coordinates[k][l]);
