Hello

Could someone please run my programme below and tell me how I can round off the double values to 2 decimal places

Many thanks

/*4. Write a program to calculate and display the amount of money in a bank
account that was opened with a deposit of €20 fifteen years ago and has
earned interest at 10% (compound interest) per annum. Your program
should display the amount of money in the account at the end of each year
for all of the 15 years.*/

public class Q4
{
	public static void main (String [] args)
	{
		double start = 20;
		double years = 15;
		double interest = 10;
		double totalInt;
		
		for (int counter = 1; counter <=15; counter ++)
		{
		
		totalInt = (start / 100) * interest;
		start = start + totalInt;
						
		System.out.println("Year " + counter + " Total €" + start);
		
		}		
       }
}

Thanks I have never used the Java Api before as I am a novice.

import java.text.DecimalFormat;
import java.text.NumberFormat;

public class Q4
{
	public static void main (String [] args)
	{
		double start = 20;
		double years = 15;
		double interest = 10;
		double totalInt;
		
		NumberFormat formatter = new DecimalFormat("0.00");
		
		for (int counter = 1; counter <=15; counter ++)
		{
		
		totalInt = (start / 100) * interest;
		start = start + totalInt;
						
		System.out.println("Year " + counter + " Total €" + formatter.format(start));
		
		}		

	}
}
