In Java 7 a new file api was introduced. This new file api is represented by the java.nio package. With the old api java.io it was possible to concatenate two file/folder easily. Let’s have a look how this works with the java.nio.file.Path
With java.io.File it was possible to use
|
1 |
new File(new File(new File("absolute"),"relative"),"file"); |
A concatenation like that is not apparently available in java.nio.file.Path. But when having a look at it there is a method called resolve. Using Path.resolve it is possible to concatenate different paths.

// in case there are different paths available that must be concatenated Path relative = Paths.get("relative"); Path file = Paths.get("file"); Paths.get("absolute").resolve(relative).resolve(file); // much easier in case there are not paths available Paths.get("absolute", "relative","file"); // bad practice Paths.get("absolute/relative/file"); |
