Formatting an output

[Peter Haugen]

I have written a program that calculates the first 100 pentagonal numbers. The problem is that I am supposed to output the answers with 10 answers on each line of the output. I have no idea how to do this. I am guessing that I would want to write a loop and format the output in the loop??? Is any other way to format the output without writing another loop? Here is what I have so far...

public class LabEx5_01PH {

	public LabEx5_01PH() {
		// TODO Auto-generated constructor stub
	}

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		System.out.println("This program outputs pentagonal numbers.");
		
		//declare variables
		double values = 100;
 
		for(double n = 1; n <= values; n++){
			//getPentagonalNumber2 is what you will output, getPentagonalNumberMethod is the name of
			//the method where the actual calculations take place and are sent up to the Main through the result called calc.
			double getPentagonalNumber2 = getPentagonalNumberMethod(n);

			//Output answer
			System.out.println(getPentagonalNumber2);}

	}

	public static double getPentagonalNumberMethod (double n){
		double calc;
		//Calculate pentagonal numbers
		calc = n * ((3 * n) - 1) / 2.0;
		return calc;
	}

}

Thanks for letting me know and I will be sure to do this in the future.

I don't know why your guess involves a loop. The normal way to do something in Java is to call a method which does that thing.
