How to have output display trailing zeros?

public class StackOF01 {

    public static void main(String[] args) {
        String schoolTown = "Minneapolis";    
        String schoolState = "Minnesota";    
        String county01 = "Ramsey";      
        String county02 = "Hennepin";   
        long censusYear = 2010;        
        long censusPopulation = 382599;  
        String censusBureau = "Census Bureau"; 
        double area = 6.60;  
        double land = 6.52;  
        double water = 0.08;  
        String river = "Mississippi";  
        String campus = "University of Minnesota-Twin Cities";  
        int sections = 2; 

        System.out.println(schoolTown + ", " + schoolState + ":\n" );
        System.out.println(schoolTown + " is a city in " + county01 + " and " + county02 + " counties in the U.S. State "
                + "of " + schoolState + ". " + "As of the census of \n" + censusYear + ", " + "there were " + censusPopulation + " people.\n" );
        System.out.println("According to the United States " + censusBureau + "," + " the school has a total area of "); 
        System.out.printf("%.2f",area);
        System.out.println(" square miles, of which,\n" + land + " square miles is land and " + water + " square miles is water.\n");
        System.out.println(schoolTown + " lies on the banks of the " + river + " River, The South Fork of the " + river + " River ");
        System.out.println("runs through the city, dividing the campus of the " + campus + " into " + sections + " sections." );
    }

}

How do I print the trailing zeros of the variable named area of type double without having to break from the print statement? I used System.out.printf("%.2f",area); to have the output display 6.60 rather than 6.6

The output looks like:

Minneapolis, Minnesota:

Minneapolis is a city in Ramsey and Hennepin counties in the U.S. State of Minnesota. As of the census of 
2010, there were 382599 people.

According to the United States Census Bureau, the school has a total area of
6.60 square miles, of which,
6.52 square miles is land and 0.08 square miles is water.

Minneapolis lies on the banks of the Mississippi River, The South Fork of the Mississippi River |
runs through the city, dividing the campus of the University of Minnesota-Twin Cities into 2 sections.

But I would like the output to display as:

Minneapolis, Minnesota:

Minneapolis is a city in Ramsey and Hennepin counties in the U.S. State of Minnesota. As of the census of 
2010, there were 382599 people.

According to the United States Census Bureau, the school has a total area of 6.60 square miles, of which,
6.52 square miles is land and 0.08 square miles is water.

Minneapolis lies on the banks of the Mississippi River, The South Fork of the Mississippi River
runs through the city, dividing the campus of the University of Minnesota-Twin Cities into 2 sections.

You can use String.format() method.

System.out.println("According to the United States " + censusBureau
    + "," + " the school has a total area of "
    + String.format("%.2f", area) + " square miles, of which,\n"
    + land + " square miles is land and " + water
    + " square miles is water.\n");

Use like this - 

System.out.print( String.format( "%.2f", area));
