Changing non-hanging braces to hanging braces

What is the regex to change 

class ABC
{
}

to 

class ABC {
}

I can use J command for one line,but how to do this for entire file.

Thanks

A few of the answers suggest using a substitution command. To me, it feels more appropriate to use a :global command in combination with the :join command. Start by creating a suitable search pattern:

/\n{

This works for the simple example given in the question, but it may need to be refined depending on the contents of the file that you are working on. Once you've got your search pattern, you can run the global command:

:g//j

If you leave the search field blank, Vim automatically uses the last search pattern (this is also true for the :substitute command). I prefer breaking the global command into two separate steps, but you could just as well do it in a one-er. Here is the long-hand form:

:g/\n{/join

For your example this worked for me on gVim: %s /class.*\zs\_[^{]*{/ {\r/

Try the following:

:%s/\(class.*\)\_.{/\1\ {/g

How about recording a macro, i.e.

/class               # search for class
gg                   # goto beginning of file
qq                   # start recording of macro
J                    # join lines
n                    # move to next match
q                    # stop recording

execute using @q

Use the following search and replace:

:%s/\n{/ {/g
