Hi, I wanna do an applet that write text information in a log file, but when the file don't exists, I need generate an exception because is needed write some data in the top of file.
This only works when the patch "c:/logs" don't exists, and I need this works when the patch exists, but not the file "logs.log"
Can somebody help me?
- string patch = "c:/logs/logs.log";
- FileWriter file;
- PrintWriter output;
- try
- {
- file = new FileWriter(patch, true); //bool tells to append
- file.write("\n");
- println("exist");
- file.close();
- }
- catch(Exception e)
- {
- output = createWriter(caminho);
- output.close();
- println("except");
- try
- {
- file = new FileWriter(caminho, true); //bool tells to append
- file.write("Some data");
- file.close();
- }
- catch(Exception e2)
- {
- e.printStackTrace();
- println();
- e2.printStackTrace();
- }
- }
This only works when the patch "c:/logs" don't exists, and I need this works when the patch exists, but not the file "logs.log"
