However, if you want to convert A to B. You must do an exclipt conversion from Father to son. Something like:B b = (B)a;And now, since every class's father class is Object. So from Object to int you must have an exclipt conversion, something like this:...

在C#或类似类型的编程语言中,当你尝试将一个double类型的值赋给一个int类型的变量时,会出现“cannot implicitly convert type 'double' to 'int'. an explicit conversion exists.”这样的编译错误。这是因为double类型可以表示小数,而int类型只能表示整数,编译器不会自动丢失小数部分来进行转换,因此需要显式地进行类...
