[1396]String and StringBuffer
By Anonymous on 2005/04/18 13:03:33 Rate
In case anyone has trouble dealing with Strings, Java's String type
is for fairly non-changing String data. There aren't any real methods
that allow you to cut/copy/paste/alter an object of type String. You
are out of luck. It is somewhat of a pain until you understand this
difference setup by Java.
An object of type StringBuffer has more methods for string changing.
When you are done messing with the StringBuffer object, ( ie. it's not
going to change anymore ) return it as a String type again through
your methods with return

By Anonymous on 2006/09/20 08:07:55 Rate
split ( ) is based on regex expression, a special attention is needed with some characters which have a special meaning in a regex expression.
For example :
String s3 = "Real.How.To";
...
temp = s3.split ( "\\." ) ;
or
String s3 = "Real|How|To";
...
temp = s3.split ( "\\|" ) ;
The special character needs to be escaped with a "\" but since "\" is also a special character in Java, you need to escape it again with another "\" !
