构造
函数中的if应该检查输入是否合法...编译器似乎不同意我的观点,它在 if 语句后给了我"';"预期",我不明白为什么请帮忙。
public class RGBColor
{
private int _red,_green,_blue;
private final int _MAX_INTENSITY = 255,_MIN_INTENSITY = 0;
/**
* Constructor for objects of class RGBColor
*/
public RGBColor()
{
_red = 0;
_green = 0;
_blue = 0;
}
public RGBColor(int red, int green,int blue)
{
If ((_red < _MIN_INTENSITY) || (_red > _MAX_INTENSITY) || (_green < _MIN_INTENSITY) || (_green > _MAX_INTENSITY) || (_blue < _MIN_INTENSITY) || (_blue > _MAX_INTENSITY)) \<<I get the error here
{
_red=0;
_green=0;
_blue=0;
}
else
{
_red = red;
_green = green;
_blue = blue;
}
}
}
你的"If"有一个大写的"I",所以编译器认为你在声明一个类型。
