The method relativize computes the difference between an absolute path (src/main/java/com/airhacks)
and it's root (src/main/java). This is useful for subtraction of a common path prefix:
import java.nio.file.Path;
import java.nio.file.Paths;
import org.junit.Test;
public class PathSubstractionTest {
@Test
public void splitWithDot() {
Path fromProjectRoot = Paths.get("src/main/java/com/airhacks");
Path projectRoot = Paths.get("src/main/java");
Path substracted = projectRoot.relativize(fromProjectRoot);
String actual = substracted.toString();
String expected = "com/airhacks";
assertThat(actual, is(expected));
}
}
