How to write a backwards-compatible code block?

This is kind of a double question.

before 1.7.9, player data was stored here:

worldName + "/player/" + p.getName() + ".dat"

Now it is stored here:

worldName + "/playerdata/" + p.getUniqueId() + ".dat"

A plugin I help to maintain broke from this update for two reasons. The "player" folder was changed to "playerdata" and the file name was changed from the player's name to the new UUID string.

My first question is whether there is a way to get the "player/playerdata" path in such a way that is not hard-coded as it is here.

My second question is how to write an expression which allows me to say, "if the version of bukkit is older than 1.7.9, execute this block, else, execute this other block".

Thanks.

 

two separate handlers and switch, i hope you will find self method to get bukkit version.

Try this, its untested though

Code:java

public File getPlayerDatFile(Player p){
String s = Bukkit.getVersion();
s = s.replaceAll(".","");
if (Integer.parseInt(s) >= 179){
    return new File("path/to/file/"+p.getUniqueId()+".dat");
} else {
    return new File("old/minecraft/path/to/file/"+p.getUniqueId()+".dat");
}
}
