Setting Locale of a Scanner on a String Example
The following example shows the usage of Java Scanner useLocale(Locale locale) method to use a locale for scanner. We've created a scanner object using a given string. We've printed a line using nextLine() method and then set a locale to print it. Then scanner is closed using close() method.
package com.tutorialspoint; import java.util.Scanner; import java.util.Locale; import java.util.regex.Pattern; public class ScannerDemo { public static void main(String[] args) { String s = "Hello World! 3 + 3.0 = 6.0 true "; // create a new scanner with the specified String Object Scanner scanner = new Scanner(s); // print a line of the scanner System.out.println(scanner.nextLine()); // change the locale of this scanner scanner.useLocale(Locale.ENGLISH); // display the new locale System.out.println(scanner.locale()); // close the scanner scanner.close(); } }
Output
Let us compile and run the above program, this will produce the following result −
Hello World! 3 + 3.0 = 6.0 true en
Setting Locale of a Scanner on User Input Example
The following example shows the usage of Java Scanner useLocale(Locale locale) method to use a locale of scanner. We've created a scanner object using System.in class. We've printed a line using nextLine() method and then set a locale to print it. Then scanner is closed using close() method.
package com.tutorialspoint; import java.util.Locale; import java.util.Scanner; public class ScannerDemo { public static void main(String[] args) { // create a new scanner with the System.in class Scanner scanner = new Scanner(System.in); // print a line of the scanner System.out.println(scanner.nextLine()); // change the locale of this scanner scanner.useLocale(Locale.ENGLISH); // display the new locale System.out.println(scanner.locale()); // close the scanner scanner.close(); } }
Output
Let us compile and run the above program, this will produce the following result −
Hello World Hello World en
Setting Locale of a Scanner on a Properties File Example
The following example shows the usage of Java Scanner useLocale(Locale locale) method to set a locale for scanner. We've created a scanner object using properties.txt file. We've printed a line using nextLine() method and then set a locale to print it. Then scanner is closed using close() method.
package com.tutorialspoint; import java.io.File; import java.io.FileNotFoundException; import java.util.Locale; import java.util.Scanner; public class ScannerDemo { public static void main(String[] args) throws FileNotFoundException { // create a new scanner with a file as input Scanner scanner = new Scanner(new File("properties.txt")); // print a line of the scanner System.out.println(scanner.nextLine()); // change the locale of this scanner scanner.useLocale(Locale.ENGLISH); // display the new locale System.out.println(scanner.locale()); // close the scanner scanner.close(); } }
Assuming we have a file properties.txt available in your CLASSPATH, with the following content. This file will be used as an input for our example program −
Hello World! 3 + 3.0 = 6
Output
Let us compile and run the above program, this will produce the following result −
Hello World! 3 + 3.0 = 6 en
