Write a log file with a size limit

This tip provides code for creating a log file. When the file reaches a certain size, a new file will be created and the existing file will be renamed.

The method below creates a log file. If the log file reaches a certain size, the method will rename the existing file and create a new one.

usage:
writeLogFile2(hLogin, hNow, "User " + hLogin + 
" Logged In", "Logged In");




public void writeLogFile2(String strWho, 
String strWhen, String strWhat, String strLeadNumber) 
     {
      String strFile;
      String gDate = String.valueOf(emcU.getDate());
      try {
           strFile = "c:\java\insRF" + strWho + "Log.txt";
              //File file = new File("c:\java\insRF" + strWho 
+ "Log.txt");
              File file = new File(strFile);
              
              long length = file.length();
              if(length > 5000)
                {                  
                  File fileOLD = new File(strFile);
                  File file2New = new File("c:\java\insRF" 
+ strWho + "Log" + gDate + ".txt");
                  boolean success = file.renameTo(file2New);
                  
                  BufferedWriter out = new BufferedWriter
(new FileWriter(strFile, true)); 
                  out.write("" + strWho + " at " + strWhen + " 
Clicked on: " + strWhat + " Action for Lead Number: "
 + strLeadNumber);
                  out.write(" ¥ ");
                  out.close();
                 }
                  else
                          {
                           BufferedWriter out = 
new BufferedWriter(new FileWriter(strFile, true)); 
                              out.write("" + strWho + " at " + 
strWhen + " Clicked on: " + strWhat + " Action for
 Lead Number: " + strLeadNumber);
                              out.write(" ¥ ");
                              out.close();
                           }
            }
            catch (Exception e) 
                  {
