Question

private static RE _TaskTypeRE = new RE("~:~([0-9]*)~");

and this requires import com.sun.org.apache.regexp.internal.RE;

So on compiling I am getting the following warning.

 warning: com.sun.org.apache.regexp.internal.RE is Sun proprietary API and may be removed in a future release
    [javac] import com.sun.org.apache.regexp.internal.RE;

One solution is to not use that class.

Another solution is to ignore the warning.
If i want to avoid this class what is the better alternative.
Thanks

Answer 1

If you need regular expressions, use the Pattern class.

private static Pattern p = Pattern.compile("~:~([0-9]*)~");

Take a look at the JavaDoc I linked to though. It may work differently.
