How do I browse CentOS packages?

Question

I want to make a log in the java code. And, the whole process takes hours to finish. But my code makes all the log at the end of the execution, because buffer is closed at the end.

Is there any method, so that I can append in the log file ?

Please see my code, and suggest some necessary changes. Thanks in advance.

My code,

public class test {

    public static void func(String url1, String url2, BufferedWriter bw) throws  InterruptedException, IOException {
        long loading_time = 10878;
        long parsing_time = 120;
        long processing_time = 329;
        Thread.sleep(100000000);  // Here is some process that performs recursively
        bw.write( url1 + "\n" + url2 + "\n"+ ((double)loading_time)/((double)1000)+ " seconds   " + ((double)parsing_time)/((double)1000) +  " seconds   "  + ((double)processing_time)/((double)1000) + " seconds\n\n\n\n" );
    }

    public static void main(String[] args) throws IOException, InterruptedException{
        try {
            FileWriter fw = new FileWriter("C:\\Users\\jhamb\\Desktop\\log.txt");
            BufferedWriter bw = new BufferedWriter(fw);
            for(int i = 0; i < 5; i++) { func("hitesh", "jhamb", bw);  }
            bw.close();
        } catch (Exception e) {
            System.out.println("Sorry some problem");
        }
    }
} 

Solution

Generically speacking

yum search "search-string"

will search any of your configured and enabled repo's, though its not always handy to use yum / rpm commands if your stuck on something like a .so.* dependency failure. EDIT: I know the above isn't web, but there are yum GUI's around that emulate that function, I just can never remember a good one so prefer the command line.

For dependencies and as a general goto for rpm searching I use: http://rpm.pbone.net/ click the advanced search link to narrow the search to your distros.

I find this an awesome resource as it doesn't just index the redhat/fedora/suse default repos, though I'm not sure if it includes RPMFusion (which is another great 3rd Party source and is searchable).

use any logging framework

@rajesh Please see my above code, and please suggest me how can I change this ?

[rajesh]

But you have to use a framework to log rather than writing yourself. This will be one think that you will use in all your code.

[rajesh]

File path will be based on your log config.

I seriously don't know anything about this, please tell me where the log config is ?
