Thread: How to write a String name variable to store letters,dotes and spaces only in Java?

Hi Java professionals,
I am trying to write a program and the name variable can only store letters,dotes and spaces. But whenever I enter a space, the program doesn't work. Please help, thanks in advance and the following is my code.

import java.util.Scanner; 
import java.util.*; 
public class Space 
{ 
public static void main(String []args) 
{ 
Scanner reader = new Scanner(System.in); 
String name,email; 
while(true) 
{ 
System.out.print("Please enter your name:"); 
name = reader.next(); 
System.out.print("Please enter your email address:"); 
email =reader.next(); 
if(name.equals("Quit")) 
{ 
System.out.println("Bye!"); 
break; 
} 
if(name.matches("[^A-Za-z]+$")) 
{ 
System.out.println("The name is invalid."); 
} 
} 
} 
}

You need to refer to the appropriate API when a method you're using is not achieving the desired results. Read the Scanner API for the next() method. Compare that to the nextLine() method.

The nextLine() method only works for one time. The program fails when there is a loop.
