Java Scanner useLocale() Method

❮ Scanner Methods

// Create a scanner object
Scanner myObj = new Scanner("1.500.000");

// Change delimiter
myObj.useLocale(new Locale("es"));

// Read and display the number
System.out.println(myObj.nextInt());

Definition and Usage

The useLocale() method changes the locale used by the scanner. The locale determines how numbers are interpreted by deciding how digits are grouped, which character serves as a decimal point, etc.

Locale objects

The useLocale() method requires a Locale object as an argument. Locale objects represent a language or country and they are used by a variety of Java classes to handle formatting and interpreting data.

The easiest way to get a Locale object is by using one of the objects provided by attributes of the Locale class.

myObj.useLocale(Locale.GERMANY));

A list of available language and country attributes is shown below.

If the country or language you need is not in the list then you can create a new Locale object using a language code and an optional country code. Most codes are two or three characters long and each code represents a language or a country.

Locale spanish = new Locale("es");
Locale spain = new Locale("es", "ES");
