我想做一个计算器,在放置按纽时,我想通过一个数组来设置按纽。
于是我这样写:
private Button []b;
private Panel pcontainer;
setLayout(new GridLayout(3,3));
for(int i = 1; i<=9; i++)
{
b[i] = new ButtonLight Bulb;
pcontainer.add(b[i]);
}
可是,编译器提示Button()中只能放置字符串,于是我设置:
b[i] = new Button(toString Light Bulb);
但编译器还是不通过:
cannot resolve symbol
symbol : method toString (int)

难道只能手工一个一个放置按纽么???

请大家帮忙!!!

你这个toString是哪个类的成员方法?如果要放0~9,直接这样用就可以了
b[i] = new Button(""+i);
