Use of Scanner class and Delimiter

[tjhodge]

How would i use the scanner class to read a textfile called "music". It contains data in the form;

David/Grey#Elton/John#Micheal/Buble#Celine/Dion#

/ - splits up the name
# - marks end of person

i would like to put them in to the fields 'forename' and 'surname' for printing.

an easy solution could be:

scan = new Scanner(new File("music.txt"));
			
scan.useDelimiter("#");
			
while(scan.hasNext()){
				
	String[] list = scan.next().split("/");
	System.out.println("name = "+list[0]);
	System.out.println("surname = "+list[1]);
}

the important parts are the settings of delimiters in scanner and in split....
a delimiter can be any regular expression

hope it helped

Sorry i did not make it very clear. The main method should input one person’s data at a time, assign that person’s names to two String variables called forename and surname, respectively, and then print out forename and surname on a line.

i understand that i need the two variables
String forename;
String surname;

and i have

try
{
filescan = new Scanner(new File("music"));
}
catch(Exception e)
{
System.out.println(e);
}
filescan.useDelimiter("#");

Its the fact of breaking up the string
David/Grey#...etc
and putting it into the two String variables then printing.

sorry sorry.....
or i don't understand what you want to do or you don't understand the code i wrote.....

i splitted all your text file....
the scanner gets me strings like "name/surename"
and then the split gets me an array containing ["name","surename"]

so....

String name = list[0];
String surname = list[1];

// and we write it to the same line
System.out.println(name+" "+surename);
