java - javame中自己的异常

Question

我可以用一个(自己编写的)catch 替换所有catch 并在自己编写的catch 中捕获的异常类型之间切换吗？这样我就可以轻松地在异常中进行调试。

try {
            int recordId = recordstore.addRecord(data, 0, data.length);

        } catch (RecordStoreFullException e) {
            e.printStackTrace();
                    System.out.println("debuginfo");
        } catch (RecordStoreNotOpenException e) {
            e.printStackTrace();
                    System.out.println("debuginfo");
        } catch (RecordStoreException e) {
            e.printStackTrace();
                    System.out.println("debuginfo");
        } catch (NullPointerException e) {
            e.printStackTrace();
                    System.out.println("debuginfo");
        } catch (Exception e) {
            e.printStackTrace();
                    System.out.println("debuginfo");
        }

你有什么理由不这样做吗？

try {
    int recordId = recordstore.addRecord(data, 0, data.length);

} catch (Exception e) {
    // or use a logging framework.
    System.err.println("debuginfo");
    e.printStackTrace();
}
