[java] Importing packages in Java

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!");
    }
}

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();
    }
}

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

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

Take out the method name from in your import statement. e.g.

import Dan.Vik.disp;

becomes:

import Dan.Vik;

Here is the right way to do imports in Java.

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

You don't import methods in java. There is an advanced usage of static imports but basically you just import packages and classes. If the function you are importing is a static function you can do a static import, but I don't think you are looking for static imports here.

For the second class file, add "package Dan;" like the first one, so as to make sure they are in the same package; modify "import Dan.Vik.disp;" to be "import Dan.Vik;"

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

We can also import static methods/fields in Java and this is how to import

import static full.package.nameOfClass.staticMethod;
import static full.package.nameOfClass.staticField;

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

to import static methods/fields use

import static full.package.name.of.SomeClass.staticMethod;
import static full.package.name.of.SomeClass.staticField;

You should use

import Dan.Vik;

This makes the class visible and the its public methods available.
