Note4代码简洁之道-Chapter3

1. 抽离Try/Catch代码块。他们搞乱了代码结构，把错误的处理与正常流程混为一谈。

最好把try和catch代码块的主题部分抽离出来，另外形成函数。

public void delete(Page page){
  try{
    deletePageAndAllReference(page);
  }catch(Eception e){
    logError(e);
  }
}


private void deletePageAndAllReference(Page page) throws Exception{
  deletePage(page);
  ....
  ....
}

有了这样美妙的区隔，代码就更易于理解和修改了。 ····························································································
