Running the following in Eclipse initially caused Scanner to not recognize carriage returns in the console effectively blocking further input:

price = sc.nextFloat();

Adding this line before the code causes Scanner to accept 0,23 (french notation) as a float:

Locale.setDefault(Locale.US);

This is most probably due to regional settings in Windows XP Pro. When the code is run again 0,23 is still accepted and entering 0.23 causes it to throw a java.util.InputMismatchException.

Any explanation as to why this is happening? Also is there a workaround or should I just use Float#parseFloat?

Edit:

import java.util.Locale;
import java.util.Scanner;


public class NexFloatTest {

 public static void main(String[] args) {

  //Locale.setDefault(Locale.US);
  //Locale.setDefault(Locale.FRANCE);

  // Gives fr_BE on this system
  System.out.println(Locale.getDefault());

  float price;

  String uSDecimal = "0.23";
  String frenchDecimal = "0,23";

  Scanner sc = new Scanner(uSDecimal);

  try{
   price = sc.nextFloat();
   System.out.println(price);
  } catch (java.util.InputMismatchException e){
   e.printStackTrace();
  }

  try{
   sc = new Scanner(frenchDecimal);
   price = sc.nextFloat();
   System.out.println(price);
  } catch (java.util.InputMismatchException e){
   e.printStackTrace();
  }

  String title = null;
  System.out.print("Enter title:");

  try{
  title = sc.nextLine(); // This line is skippe
  } catch(java.util.NoSuchElementException e ){
   e.printStackTrace();
  }

  System.out.print(title);
 }

}
