Examples of java.nio.file.Path.resolve()

java.nio.file.Path.resolve()
Resolve the given path against this path.
If the {@code other} parameter is an {@link #isAbsolute() absolute}path then this method trivially returns {@code other}. If {@code other}is an empty path then this method trivially returns this path. Otherwise this method considers this path to be a directory and resolves the given path against this path. In the simplest case, the given path does not have a {@link #getRoot root} component, in which case this methodjoins the given path to this path and returns a resulting path that {@link #endsWith ends} with the given path. Where the given path hasa root component then resolution is highly implementation dependent and therefore unspecified. @param other the path to resolve against this path @return the resulting path @see #relativize
