How to implement this?

I want all the classes write the runtime information into one common
file, let's say, log.
So I define a BufferedWriter log in one of the classes and make it
public static, as follows,

import java.io.BufferedWriter;
import java.io.FileWriter;

public class Tester {

                static String path = "/home/xi/Desktop/D2V/
validation/";
                static FileWriter fwlog = new FileWriter(path +
"log");
                public static BufferedWriter log = new
BufferedWriter(fwlog);
                //the rest code
}

However, the constructor of FileWriter throws exception so it does not
compile:
--------------------
Tester.java:11: unreported exception java.io.IOException; must be
caught or declared to be thrown
                static FileWriter fwlog = new FileWriter(path +
"log");
                                          ^
1 error
--------------------

What can I do to handle this exception?

looks like I cannot either catch it here or put the "throws
IOException...." sentence after "public class Tester".
