r/java on Reddit: What was the thought process behind the design of the NumberFormat class? Why doesn't it have a way to set a pattern?

June 2, 2024 -

I know that the sub class DecimalFormat has a way to set the pattern, but it instead doesn't have a way to set the locale.

So, if you want to set both the locale and the pattern, you have to use one of the getInstance methods of the NumberFormat class, and then cast the result to a DecimalFormat in order to call the applyPattern method.

But the getInstance methods of NumberFormat doesn't guarantee which subclass you will get. Even if the code works now, it might break in the future.

What were they thinking when they designed these classes? Or is my use case here really an anomality?

Edit: I found a proper way of handling this, using the alternative constructor:

DecimalFormat decimalFormat = new DecimalFormat("#,##0.00", DecimalFormatSymbols.getInstance(Locale.US));
