class HUMAN
{
private double height;
public void set_height(double height)
{
this.height = height;
}
public void get_height(void)
{
System.out.println("height is %.2f\n", height);
}
}
public class mike
{
public static void main(String[] args)
{
HUMAN mike_1 = new HUMAN();
mike_1.set_height(333.33);
mike_1.get_height();
}
}
public void get_height(void) 这有问题吧 ，这能用void的做参数吗？
class HUMAN
{
private double height;
public void set_height(double height)
{
this.height = height;
}
public void get_height()
{
System.out.println("height is %.2f\n,"+ height);
}
}
public class mike
{
public static void main(String[] args)
{
HUMAN mike_1 = new HUMAN();
mike_1.set_height(333.33);
mike_1.get_height();
}
}追问

如果不需要接收形参，不可以用void吗？
追答不可以，改了几个报错得地方你仔细看一下。这个是不是要运算一下，还就是输出个数？
追问我记得C语言中应该加void，难道这是C和JAVA不同？
追答没有用过c可能不一样吧
