如何将方法从包导入另一个程序？我不知道如何导入...我写了一个lil'代码:
package Dan;
public class Vik
{
public void disp()
{
System.out.println("Heyya!");
}
}
然后,将其保存在名为"Dan"的文件夹中,然后编译它.生成.class文件.然后,我在下面写了这段代码:
import Dan.Vik.disp;
class Kab
{
public static void main(String args[])
{
Vik Sam = new Vik();
Sam.disp();
}
}
然后我将它保存在文件夹"Dan"之外,它说:"找不到符号"
我在C:\ Dan\Vik.java中保存了第一个代码,在C:\ Kab.java中保存了第二个代码

var b = parseInt(prompt("Enter G"));
var c = parseInt(prompt("Enter B"));
document.body.style.backgroundColor=rgb(a,b,c);
</script>

为什么背景颜色不会根据RGB值变化？我做错了什么？
