删除空白块在Emacs

Question

我常常落得这样的代码块：

public class CustomFile { 

    public String path; 
    public String name; 





    public CustomFile (String pathToFile, String dbName) { 
    path = pathToFile; 
    name = dbName; 
    } 
} 

我希望能够把我的光标就行了上述public CustomFile并能够删除所有空白最多但不包括public String name;。有没有可以让我这样做的命令或宏？

这看起来像你想要什么：

C-x C-o runs the command delete-blank-lines, which is an interactive 
compiled Lisp function in `simple.el'. 

It is bound to C-x C-o. 

(delete-blank-lines) 

On blank line, delete all surrounding blank lines, leaving just one. 
On isolated blank line, delete that one. 
On nonblank line, delete any immediately following blank lines.
