求助（Java画板上不断圆时出现"AWT-EventQueue-0" java.lang.IndexOutOfBoundsException: ）

[snaillxc]

for( int i = 0 ; i < ga.pl.size(); i ++){
	if( 1 == ga.location[ga.pl.get(i).getX()/6][ga.pl.get(i).getY()/6]){
         /*其他代码主要是这一行
          */
         if( 1 == ga.location[ga.pl.get(i).getX()/6][ga.pl.get(i).getY()/6]){
					new                                      Circle(ga.pl.get(i).getX(),ga.pl.get(i).getY(),6,Color.GREEN).draw(g);

我在初始化时pl.size()长度是40，在后来程序不断运行，pl.size()长度会不断增加，需要在相应的位置上画圆。当长度大于40时就会出现这个异常。
求助！！！这个该怎么解决。。。谢谢！！感激不尽。。

越界吧，

[ggg957432]

问题很明显，是下标越界异常！好好检查一下代码

楼主贴出的东西只能像楼上两位那样分析　了

这句代码里应该有数组越界的操作，建议楼主debug试下，首先确定List的大小，然后确认get(int index)索引的大小，判断一下，是否会有index>=size
