Importing packages in Java

Question

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          


        

Answer 1

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();
    }
}

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

Answer 2

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.

Answer 3

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;

Answer 4

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;

Answer 5

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;"

Answer 6

You should use

import Dan.Vik;

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