The DecimalFormat class has a method called setGroupingSize() which sets how many digits of the integer part to group. Groups are separated by the grouping separator. Hence you can use setGroupingSize() method to change the default group digits number as you need.

The following example demonstrates setting grouping separator for integer part of the decimal number:

The above code produces the following output:

170180.24551 GroupSize(4) = 17,0180.246

As mentioned in earlier posts, the java.text.DecimalFormat class is used to format decimal numbers via predefined patterns specified as String.

Apart from the decimal separator, grouping separator, currency separator etc., It is also possible to mix String literals within the pattern.

The following example demonstrates embedding String literals within pattern:

The above code produces the following output:

My formatted number is 170,180.246

You can customize which symbols are used as decimal separator, grouping separator, currency seperator etc. using a DecimalFormatSymbols instance together with java.text.DecimalFormat class.

The DecimalFormatSymbols instance can be passed to java.text.DecimalFormat constructor followed by the call to format() method of java.text.DecimalFormat to achieve the desired decimal separator, grouping separator character etc.

The following example demonstrates formatting using DecimalFormatSymbols:

The above code produces the following output:

$170:180-246

If you want to create a DecimalFormat instance for a specific Locale, create a NumberFormat and cast it to a DecimalFormat.

The java.text.DecimalFormat class is used to format numbers using a user specified formatting. This concrete subclass of NumberFormat, allows formatting decimal numbers via predefined patterns specified as String . It has a variety of features designed to make it possible to parse and format numbers in any locale.

The following example demonstrates decimal formatting as per specified locale:

The above code produces the following output:

170,180.245 - English (en)
170 180,245 - French (France) (fr-FR)
170.180,245 - German (de-DE)

This concrete subclass of NumberFormat, allows formatting decimal numbers via predefined patterns specified as String. It has a variety of features designed to make it possible to parse and format numbers in any locale

The following example shows formatting decimal numbers using various string patterns:

The above code produces the following output:

    170180.24523 -> 170180.24523
    170180.24523 -> 170180.245
    170180.24523 -> 170180.245230
    170180.24523 -> 170180
    170180.24523 -> 0170180.245
    170180.24523 -> 17018024.52%
