在Java中，我们可以在catch或finally块中使用return语句吗？

public class CatchReturn {
   int calc() {
      try {
         int x=12/0;
      } catch (Exception e) {
         return 1;
      }
      return 10;
   }
   public static void main(String[] args) {
      CatchReturn cr = new CatchReturn();
      System.out.println(cr.calc());
   }
}

public class FinallyReturn {
   int calc() {
      try {
         return 10;
      } catch(Exception e) {
         return 20;
      } finally {
         return 30;
      }
   }
   public static void main(String[] args) {
      FinallyReturn fr = new FinallyReturn();
      System.out.println(fr.calc());
   }
}
