////添加 单选按钮
private String[][] strrb4={{"黑","棕","红","橙","黄","绿","蓝","紫","灰","白"},{"金","银"}};
JRadioButton[] rb41_ = new JRadioButton[10];
JRadioButton[] rb42_ = new JRadioButton[10];
JRadioButton[] rb43_ = new JRadioButton[10];
JRadioButton[] rb44_ = new JRadioButton[2];
//这样的话按钮名就只需一句rb4[i]_[i]=new JRadioButton;了吗
rb4[i]_[i]=new JRadioButton;可以怎么理解呀，求大神指点，我觉都睡不好。。。
for(int i =0;i<=9;i++)//String[] s:strrb4[0] )
{
rb41_[i] = new JRadioButton(strrb4[0][i]);
rb42_[i] = new JRadioButton(strrb4[0][i]);
rb43_[i] = new JRadioButton(strrb4[0][i]);
}
for(int i =0 ;i<=1;i++)
{
rb44_[i] = new JRadioButton(strrb[1][i]);
}
/*/*/***=/*=/=*/=*/=/=*=/*=/*=/*=*=/*=/*=/*=*=*=*=*==**=*=/=/*=/=*
另外 ，用for-each可以吗：
for(String[] s:strrb4[1] )
{
int i=0;
rb44_[i] = new JRadioButton(s);
i++;
}
一个一个的创建按钮实在太麻烦了，但却搞不懂怎么循环命名。。。我好像太笨了点
