12. Formatted input with Scanner and FileReader

• The Scanner class can be used for formatted input from a character file:

  
      Scanner inFile = new Scanner( new FileReader( "myfile.dat" ) );  
  
  

  To input data, call next(), nextInt(), nextDouble(), and so on:

  
      String firstName; 
      String lastName;    
      double hoursWorked; 
      double payRate; 
      double wages; 
  
      firstName = inFile.next();  
      lastName = inFile.next();   
      hoursWorked = inFile.nextDouble(); 
      payRate = inFile.nextDouble(); 
      wages = hoursWorked * payRate;
  
      inFile.close();  //close the input file
