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

java.nio.file.Path.subpath()
Returns a relative {@code Path} that is a subsequence of the nameelements of this path.
The {@code beginIndex} and {@code endIndex} parameters specify thesubsequence of name elements. The name that is closest to the root in the directory hierarchy has index {@code 0}. The name that is farthest from the root has index {@link #getNameCount count}{@code -1}. The returned {@code Path} object has the name elementsthat begin at {@code beginIndex} and extend to the element at index {@code endIndex-1}. @param beginIndex the index of the first element, inclusive @param endIndex the index of the last element, exclusive @return a new {@code Path} object that is a subsequence of the nameelements in this {@code Path} @throws IllegalArgumentException if {@code beginIndex} is negative, or greater than or equal tothe number of elements. If {@code endIndex} is less than orequal to {@code beginIndex}, or larger than the number of elements.
