finally is meant to execute regardless of whether the exception occurs, period. It can't be avoided except by resorting to dubious tactics ( as Joachim said up there ).

If the code you have in the finally block is not meant to be executed every time, don't use a finally construct; Use a simple if-construct instead

Use boolean flag:

public class TEST
{
    public static void main(String arg[]){
        boolean success=false;
        try
        {
            System.out.println("execute try");
            //what should I write hear that finally does not run.
            success=true;
        }
        catch (Exception e){
            System.out.println(e);
        }
        finally{
            if (!success)
            {
                System.out.println("execute finally");
            }
        }
    }
}

Put the code in finally into an if.

public class TEST
{
  public static void main(String arg[]){
    boolean b = true;
    try
    {
      System.out.println("execute try");
      if (something()) b = false;
    }
    catch (Exception e){
      System.out.println(e);
    }
    finally{
      if (b){
        System.out.println("execute finally");
      }
    }
  }
}

public class TEST
{
  public static void main(String arg[]){
    bool exitFinally  = false;
    try
    {
      System.out.println("execute try");
      //what should I write hear that finally does not run.
    }
    catch (Exception e){
      System.out.println(e);
    }
    finally{

        if(exitFinally)
            return;

      System.out.println("execute finally");
    }
  }
}

If you want something not to run in the "finally" block - do not put it in "finally". Finally runs always (well, except for a few cases like others have mentioned).

You need to shutdown the JVM by calling exit as:

System.exit(exit_status);

From the Java docs:

If the JVM exits while the try or catch code is being executed, then the finally block may not execute. Likewise, if the thread executing the try or catch code is interrupted or killed, the finally block may not execute even though the application as a whole continues.
