Thread: please solve my problem with "while"

Hi! I don't understand why the line related with "While" and "nextLine" does not work, also there is message that says "resorce leak: 'en' is never closed". thanks in advance. This my code:

package inicial;
 
import java.util.Scanner;
 
public class Iniciales {
 
	public static void main(String[] args) {
		Scanner en = new Scanner(System.in);
		System.out.println("Escribe tu nombre");
		String miNombre;
		miNombre  = en.nextLine();
		String e=" ", ini="";
		int c=0;
		char i;
		char espacio=e.charAt(0);
 
		while(c<miNombre.length()){
			i=miNombre.charAt(c);
			if((c==0) && (i != espacio)) {
				ini=ini+i;
			}else {
				do {
					c++;
				}while(i != espacio);
 
				c++;
				ini = ini + i;
			}
		}
 
		System.out.println("Tus iniciales son: " + ini);
	}
 
}
