How to properly display a price up to two decimals (cents) including trailing zeros in Java?

There is a good question on rounding decimals in Java here. But I was wondering how can I include the trailing zeros to display prices in my program like: $1.50, $1.00

public static String getFormattedData(String actualString) 
    {
        String subString = "0.0";

        if(actualString.contains("."))
        {   
            subString = actualString.substring(actualString.indexOf("."), actualString.trim().length()); 

            if(Double.parseDouble(subString) > 0.0)
                return actualString;
            else
                actualString = actualString.substring(0, actualString.indexOf("."));
        }
        return actualString;
    }
