Question

I have string:

String s = "~/abc/d.png"

How can I get absolute path of this file?

I’ve tried:

File file = new File(s);
String absolutePath = file.getAbsolutePath();

But it can’t reslove ~ symbol.

Answer 1

Java isn’t going to know what the ~ means since it’s a shell expansion for your home directory. You can do this before handing it off to File:

s = s.replace("~",System.getProperty("user.home"));
