Print format for 2D arrays with text

I've been trying to make a program that will just write 2D arrays with the following text through print format. The output I am expecting supposedly should look like this, don't mind the bold points they are meant for new line:

Name : Florence
Tel. # : 735-1234
Address: Chicago
*
Name : Joyce
Tel. # : 983-3333
Address: Evanston
*
Name : Becca
Tel. # : 456-3322
Address: Oak Park

This is my code so far:

public static void main(String[] args) {
    String[][] entry = {
            {"Florence", "735-1234", "Chicago"},
            {"Joyce", "983-3333", "Evanston"},
            {"Becca", "456-3322", "Oak Park"}};

    for (int i = 0; i < entry.length; i++) {
        for (int q = 0; q < entry[i].length; q++) {
            System.out.printf("\n%s\n%s\n%s",
                    "Name   :   " + entry[i][q],
                    "Tel. # :   " + entry[i][q],
                    "Address:   " + entry[i][q]);
        }
        System.out.println();
    }
}

But my output only shows this:

*
Name   :   Florence
Tel. # :   Florence
Address:   Florence
Name   :   735-1234
Tel. # :   735-1234
Address:   735-1234
Name   :   Chicago
Tel. # :   Chicago
Address:   Chicago
*
Name   :   Joyce
Tel. # :   Joyce
Address:   Joyce
Name   :   983-3333
Tel. # :   983-3333
Address:   983-3333
Name   :   Evanston
Tel. # :   Evanston
Address:   Evanston
*
Name   :   Becca
Tel. # :   Becca
Address:   Becca
Name   :   456-3322
Tel. # :   456-3322
Address:   456-3322
Name   :   Oak Park
Tel. # :   Oak Park
Address:   Oak Park

Any tip or advice will be greatly appreciated.

though most of the code you've written is correct, you just don't need 2nd for loop. Below is why

when q=0, your code is printing
Name = entry[0][0]
Tel. #= entry[0][0]
Address = entry[0][0]
when q=1, your code is printing
Name = entry[0][1]
Tel. #= entry[0][1]
Address = entry[0][1]
when q=2, your code is printing
Name = entry[0][2]
Tel. #= entry[0][2]
Address = entry[0][2]

I think, here you got fair idea on what happens next. Above process goes on till i<3 and q<3.
This type of printing you can avoid just by excluding 2nd for loop in your code and add something like below

for ( int i= 0; i < entry.length; i++){
               System.out.printf("\n%s\n%s\n%s", "Name   :   " + entry[i][0], "Tel. # :   " +entry[i][1], "Address:   " + entry[i][2]);
           System.out.println();
       }

when above code snippet runs, you can see the expected output as you mentioned above.
when i=0, your code is printing
Name = entry[0][0]
Tel. #= entry[0][1]
Address = entry[0][2]
Next 2 steps you can follow I guess.

Hope this is helpful.

The easiest way to do this would be to use Arrays.deepToString(entry).

However that comes at the cost that you cannot specify anything between the array elements. If your priority is to display the additional Text, I suggest the other answer already present. If your priority is a well working, understandable and fast-to-code solution, then my suggestion works better.
