用Java导入包

问题描述：

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：

How to import a method from a package into another program? I don't know how to import... I write a lil' code:

package Dan;
public class Vik
{
    public void disp()
    {
        System.out.println("Heyya!");
    }
}

然后将其保存在名为Dan的文件夹中我编译了它。生成.class文件。然后，我在下面编写了这段代码：

and then, saved it in a folder named "Dan" and I compiled it. The .class file is generated. Then, I wrote this code below:

import Dan.Vik.disp;
class Kab
{
    public static void main(String args[])
    {
        Vik Sam = new Vik();
        Sam.disp();
    }
}

我把它保存在文件夹Dan之外它说：找不到符号

and I saved it outside the folder "Dan" and it says : "cannot find symbol"

我将第一个代码保存在C：\ Dan \ Vik.java
中，第二个代码保存在C：\\ \\ kab.java

I saved the first code in C:\Dan\Vik.java and the second in C:\Kab.java

答

你不用Java导入方法，只有类型：

You don't import methods in Java, only types:

import Dan.Vik;
class Kab
{
    public static void main(String args[])
    {
        Vik Sam = new Vik();
        Sam.disp();
    }
}

例外是所谓的静态导入，它允许您从其他类型导入类（ static ）方法。

The exception is so-called "static imports", which let you import class (static) methods from other types.
