Organization of projects in packages

Question

I am doing a study on Java and would like to learn without using those Ides full of resources that do everything. After several attempts to learn how to use packages by creating them manually, one class is failing to see others outside the package. Follow a totally generic example:

The folder structure is as follows:

-pacotes
 Teste.java(classe com main)
 --objeto
   Texto.java

And the file codes are as follows::

-> Java test.

package pacotes;
import pacotes.objeto.*;

public class Teste{

    public static void main(String[] args) {

        Texto t = new Texto();
    }
}

-> Java text.

package pacotes.objeto;

public class Texto{

    public Texto(){
        System.out.println("Construiu um objeto");
    }
}

When compiling the Text.java file everything happens normally, but when compiling Test.java says the package 'packages.object' does not exist, which is wrong?

Answer 1

By the way you are doing everything in text editor, IE, you are not using an IDE.

You need to specify the package to compile:

C:\Users\Leandro\Documents\Java\Exercícios\testes>javac pacotes/Teste.java

Answer 2

Don’t use wildcards this is *

with that you can make:

package pacotes;

import pacotes.objeto.Texto;


public class Teste{

    public static void main(String[] args) {

        Texto t = new Texto();
    }
}

Detail the Text constructor should be declared as public (if it is not protected and restricted to the package pacotes.objeto).

package pacotes.objeto;

public class Texto{

    public Texto(){
        System.out.println("Construiu um objeto");
    }
}
