程序运行不起来；语法好像没错； java --------------------编程问答-------------------- 除 --------------------编程问答-------------------- 提示什么错误？ --------------------编程问答-------------------- 首先确保图片位置放对
mouses = new JLabel[6];--------------------编程问答-------------------- 初学者就这么厉害了啊~
for (int i = 0; i < 6; i++)
{
mouses[i] = new JLabel();//这里先对mouses中的元素初始化。
