简单的java防止反编译

import java.util.Random;

public class TestDemo {

public static void main(String[] args) {
	  try {
	      System.out.println("-------");
	      //防止反编译的处理
	      if (654789 == new Random().nextInt()) {
	        throw new Exception("fewt43");
	      }
	  } catch (Exception ex) {
	      ex.printStackTrace();
	  } finally {
		  try {
	        //防止反编译的处理
	        if (654789 == new Random().nextInt()) {
	          throw new Exception("fewt43");
	        }
	      } catch (Exception ex) {
	        System.out.print(ex);
	      }
    }
}
