Why is The Constructor Expecting a class When I put an Array as a Parameter - JavaFx [closed]

Question

I am working on a javaFX project that expects the user to press a button to store information inputed on the text fields. What is stumping me is how to pass the String values that I have collected from the text fields into the other class, DisplayStage, that I made to display the stage of the values input by the user. My instructor, says that I am supposed to pass the array of the strings by using the constructor of the other class I created, DisplayStage. This is what I tried:

btnAdd.setOnAction((e) -> {
            
            // i keeps count of how many times the button was pushed
            this.i++; 
            //Setting the size of the array to be as big as how many times it was clicked
            String [] dataEntries = new String [this.i];  

            //Inside info, we will store the Data inputed by the user
            info =  txtID.getText() + " , " + txtName.getText() + " , " + txtAdress.getText() + " , " + txtCity.getText();
            
            // At index i-1 of dataEntries[], store the new entry stored insode of info
            dataEntries[i-1] = info;
            
            DisplayStage saveNewEntry = new  DisplayStage(dataEntries[]);        
        
        });

the constructor in the DisplayStage class expects a String array.

What I found out from putting this into practice is that, constructors are not like methods and you cannot pass an array like this, instead, by looking at the compilation error message I know that I am supposed to reference a .class. I might be missing something like a special Syntax that I can use to pass the array to the constructor or maybe I should create a class that stores the data from the user and then reference that class inside the constructor?

Thank you.

You can pass arrays in constructors just like any other objects by name:

DisplayStage saveNewEntry = new DisplayStage(dataEntries);

And your constructor can be defined like this:

public DisplayStage(String[] values) {
   // Your code
}
