simple jsp string comparison

[Jason]

Hi,

In JSP do we have a built in function like left() if we want to evalue a
string's left some characters?
Thanks.

Look at class java.lang.String, method startsWith(String prefix) and
startsWith(String prefix, int toffset).

Always refer to the API docs first.

String a = "ABCDEFG";
String firstFour = a.substring(0, 4);

firstFour will contain "ABCD"
