		fname=in.next();
		System.out.println("Enter last name: ");
		lname=in.next();
		
		char f1=fname.charAt(0);
		char f2=lname.charAt(0);
		System.out.print("Initials: "+f1+"."+f2+"."+"\n");
		
		System.out.print("Name in address book: "+fname+" "+lname.toUpperCase()+"\n");
		
		String username=f1+lname;
		System.out.print("Username: "+username.toLowerCase()+"\n");
