extracting string using IndexOf ? 1

[Ngai88]

Hello,
I want to extract the first name off a list of names separated by '<br>', what is the correct way of doing it?

i.e.

John<br>James<br>Lisa<br>Mary<br>

I want the name 'John' only.

thanks,
Ngai

String line = "John<br>James<br>Lisa<br>Mary<br>";
String john = line.substring(0, line.indexOf("<br>"));

Or to break the String into an array of Strings holding te names :

		String line = "John<br>James<br>Lisa<br>Mary<br>";
		String[] names = line.split("<br>");
		for (int i = 0; i < names.length; i++) {
			System.out.println(names[i]);
		}

If you want to get only the first one, I'd use the first sedj's example. But be sure there is at least one "<br>" or an exception will be thrown.

If you want to take all names, use the second one. But the method split(), AFAIK is since JDK 1.4. If you have an older version you can use StringTokenizer class.
