## Using format()/printf() for formatting and Scanner for parsing localized elements

07.05.2007 · [Christian Ullenboom](https://tutego.de/blog/javainsel/author/admin/)

`format()` from `String` or `printf()` from e.g. PrintWriter will use the default language except you give a Local object as the first argument:

```java
String s1 = String.format( Locale.ENGLISH, "%,.2f", 1000234234.56772345 );String s2 = String.format( Locale.FRANCE, "%,.2f", 1000234234.56772345 );System.out.println( s1 );                               // 1,000,234,234.57System.out.println( s2 );                               // 1 000 234 234,57
```

And the class `Scanner` offers `nextDouble()` that uses the default language too except you use `useLocale()`.

```java
double s1p = new Scanner( s1 ).useLocale( Locale.ENGLISH ).nextDouble();double s2p = new Scanner( s2 ).useLocale( Locale.FRENCH ).nextDouble();
```

The methods `format()`/printf() and the class `Scanner` are very handy and easy to use.
