Formatting number in Java

[sbasak]

Can anyone please tell me how to display the number in 7.50 ie. 2 digit after decimal format? I'm utterly confused after searching thru Java documentation.

public class Test
{
public static void main(String args[])
{
System.out.println("Hello World");
double x=50,z;
z=Math.sqrt(x);

System.out.println("The square root of 50 is " +z);
}
}


Thanx

NumberFormatter class, maybe?

I'm looking for exact syntax/example. I also searched for NumberFormat class but couldn't make it work

import java.text.DecimalFormat;
import java.text.FieldPosition;
import java.lang.StringBuffer;
import java.text.NumberFormat.Field;
import java.lang.System.*;

class temp
{
	public static void main(String [] args)
	{
		DecimalFormat decFormat = new DecimalFormat("#,##0.00");
		StringBuffer buff = new StringBuffer();
		decFormat.format(1234.56, buff, new FieldPosition(Field.DECIMAL_SEPARATOR));
		
		System.out.println(buff.toString());
	}
}
