import java.text.NumberFormat;

public class CurrencyformatDemo
{
public static void main(string[] args)
{
System.out.println("Without formatting:");

System.out.println(19.8);
System.out.println(19.81111);
System.out.println(19.89999);
System.out.println(19);
System.out.println();

System.out.println("Default location:");
NumberFormat moneyFormatter = NumberFormat.getCurrencyInstance();

System.out.println(moneyFormatter.format(19.8));
System.out.println(moneyFormatter.format(19.81111));
System.out.println(moneyFormatter.format(19.89999));
System.out.println(moneyFormatter.format(19));
System.out.println();

System.out.print("US as location:");
NumberFormat moneyformatter2 = NumberFormat.getCurrencyInstance(locate.US);

System.out.println(moneyFormatter2.format(19.8));
System.out.println

代码我改了，你错了几个地方，要详细的答案的话，我明天在跟你说，现在太晚了如string要写成String，以后要多练习，这种错就不该犯。
