由于NumberFormat将负责格式化您的余额，您不需要使用String.format对其进行格式化。
因此，您可以使用类似以下的代码：
System.out.println("Checking account balance = " + nf.format(balance));
仅为了强调，我还从文本中删除了$，因为NumberFormat会为您处理这部分内容。
英文:
As the NumberFormat will be the responsible for formatting your balance, you don't need to format it using String.format.
So you could use something like that:
System.out.println("Checking account balance = " + nf.format(balance));
Just to highlight, I've removed also the $ from the text, as the NumberFormat will handle that for you.

使用 nf.format(value) 根据所需的区域设置对值进行格式化。
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.CANADA);
String balance = nf.format(this.balance);
System.out.println("Checking account balance = " + balance);
英文:
Use nf.format(value) to format the value as per locale needed.
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.CANADA);
String balance = nf.format(this.balance);
System.out.println("Checking account balance = "+balance);

你可以尝试以下内容：
String number = String.format("%.2f", this.balance);
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.CANADA);
System.out.println("Checking account balance = " + nf.format(Double.valueOf(number)));
余额将按你的要求进行格式化，然后转换为货币格式。
英文:
You can try the following
String number = String.format("%.2f", this.balance);
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.CANADA);
System.out.println("Checking account balance = "+ nf.format(Double.valueOf(number)));
The balance is formatted as you wish and then it is converted to the currency format
