How to indent string and double results in Java?

My question concerns the indentation of the results specifically. Some are String and some double. So far I have the following java program shown at the below. I need the following result:

Name:             Yoda Luca
Income:           %5000.00
Interests:        Swimming, Hiking

I don't want to have to write a prefix for every line. Is there a quicker way to format once for "String" and once for "Double" ?

Program:

import java.util.Scanner;

public class forTesting {
    public static void main(String[] args) {
        String prefixName = "Name:"; 
        String prefixIncome = "Income";

        String Name;
        double Income;

        //create a Scanner that is connected to System.in
        Scanner input = new Scanner(System.in);

        System.out.print("Enter name:");
        Name = input.nextLine();

        System.out.print("Enter income for period: ");
        Income = input.nextDouble();

        String format = "%-40s%s%n"; 
        System.out.printf(format, prefixName,Name);
        System.out.printf(format, prefixIncome, Income);
    }
}

String format takes format and followed by n number of arguments.

Yes. %f is for double and you can write them in one shot.

String format = "%-40s%s%n%-40s%f%n";
System.out.printf(format, prefixName,Name,prefixIncome, Income);

And that gives you floating point double. To get it in standard format
