Package usage difference in Delphi/Lazarus and Java

Question

I would like to know the difference of use of packages in projects Java for use of packages in projects Delphi/Lazarus?

In the Java so I know it’s about separating the classes into folders that the existence of the same within that context makes sense. But in the Delphi/Lazarus I found some mixed opinions where in some places they said that the packages would be as reusable modules beyond some places nor show the use of them, I would like to know the opinion of someone who knows the 2 worlds.

Answer 1

Indeed, in Delphi, normally Packages are created to be reused. Packages are treated as a framework.

This does not mean that you cannot modularize your system using Packages if you wish. But if you want to separate classes and modules, you don’t need to create a package. Can do using Unit Scope Names and Unit Namespaces.

Note that the operation is a little different of other languages.

Answer 2

In Java your concept is correct.
In Delphi the use of packages or Packages serves more specifically to modularize a system. However, the organization of classes can be done in these packages as well as in Java. Remembering whenever it is possible to work with Object Orientation in Delphi as well as in Java. Unfortunately many Delphians use the tool the wrong way (only procedural), and that ends up denigrating the image of Delphi and good Delphians.
There are several benefits to using packages in the Delphi.
