How can I use two different packages for methods inside one java file?

[thick barn]

Hello, I have a populator java file where I populate data, but I have two different java files where I will use this populator, but it takes only one specific dataStructure, how can I make so it will be dynamic so i can use it for both java files?

public void populateFromComposition(DataStructure dataStructure, Train input) { ```
And inside my java files i have like populator.populateFromComposition(template, input) for example. But I want to use this dyanmic inside multiply files

One way to make the populator method dynamic so it can be used with multiple Java files and data structures is to use Java Generics. You can modify the signature of your method to accept a generic type parameter instead of a specific data structure, like this:

public <T> void populateFromComposition(T dataStructure, Train input) {
// your implementation here
}

With this change, the method can now accept any data structure type. When you call the method, you specify the actual data structure type as the type argument, like this:

DataStructure template = new DataStructure();
populator.populateFromComposition(template, input);

// Or

AnotherDataStructure anotherTemplate = new AnotherDataStructure();
populator.populateFromComposition(anotherTemplate, input);

Thanks, but is it possible to make data DataStructure dataStructure dynamic? Right now I have a package like a84 and I have another package called a100 and I want to use the exact same code but just have a DataStructure to be dynamic from a84 to a100 if you get me
