Why is Path.resolve() not working in my code?

Here is my code:

public static Path changePath(Path pathInput) throws IOException
{
  Path pathOutput = pathInput;
  System.out.println(pathOutput);
  pathOutput.resolve("test.xxx");
  System.out.println(pathOutput);
  return pathOutput;
}

pathInput is a directory. pathOutput should return a file with the directory + / + test.xxx

Both System.out.println lines output the same string; the pathInput!

Perhaps the problem lies with the line pathOutput = pathInput. I tried to create a new Path() object but it said that you couldn't.

Regards.

Path is immutable. As the javadoc states

Implementations of this interface are immutable and safe for use by multiple concurrent threads.

Reassign it

pathOutput = pathOutput.resolve("test.xxx");

before you return it.
