出错原因都写在程序内了

Answer 2

public void paint(Graphics g) 方法改为
public void paint(Graphics g) //绘画棋盘和棋子
{
boolean bolFlg=false;
int iSave=0;
int bSave=0;
g.drawImage(back,45,45,420,420,this);
for(i=0,b=0;i<=14;i++,b++) //对五子棋同色达到五颗的消除
{
if (bolFlg==true) {
bolFlg=false;
break;
}
iSave = i;
bSave=b;
i=i*15;
b=(b*15)+14;
d=0;

while(i<=b)
{

if(st[i]==1) {
d++;
}
else {
d=0;
}

if(d==5) {
for(d=5;d>0;d--) {
st[i]=0;
i--;
}
bolFlg=true;
break;
}
else {
i++;
}

}

i=iSave;
b=bSave;
d=0;

}

for(i=0;i<=224;i++)
{
if(st[i]==1)
{
s2[y]=i/15*30+30;
s1[x]=i%15*30+30;
g.setColor(Color.black);
g.drawOval(s1[x],s2[y],30,30); //以(s1[x],s2[y])为正方形顶点，在正方形中画直径为30的圆
g.fillOval(s1[x],s2[y],30,30);
}
}
for(i=0;i<=224;i++)
{
if(st[i]==2)
{
s2[y]=i/15*30+30;
s1[x]=(i%15+1)*30;
g.setColor(Color.white);
g.drawOval(s1[x],s2[y],30,30);
g.fillOval(s1[x],s2[y],30,30);
}
}
}
