### Question:
Identifiers { public static Identifier replacePathSegments(Identifier base, int start, int end, String replacement) { return transformer(base).replacePathSegments(start, end, replacement).apply(); } private  Identifiers(); static Identifier withNamespace(Identifier base, String namespace); static Identifier withPath(Identifier base, String path); static Identifier prefixPath(Identifier base, String prefix); static Identifier suffixPath(Identifier base, String suffix); static Identifier truncatePath(Identifier base, int start); static Identifier truncatePath(Identifier base, int start, int end); static Identifier replacePathSegments(Identifier base, int start, int end, String replacement); static Identifier remove(Identifier base, int start, int end); static IdentifierTransformer transformer(Identifier base);  }### Answer:
@Test void replacePathSegments() { Identifier base = new Identifier("foo:bar/baz/qux"); assertEquals(new Identifier("foo:bar/quuz"), Identifiers.replacePathSegments(base, 1, 3, "quuz")); assertThrows(IndexOutOfBoundsException.class, () -> Identifiers.replacePathSegments(base, -1, 2, "quuz"), "Negative start index did not cause exception!"); assertThrows(IndexOutOfBoundsException.class, () -> Identifiers.replacePathSegments(base, 1, 4, "quuz"), "End index > segment count did not cause exception!"); assertThrows(IllegalArgumentException.class, () -> Identifiers.replacePathSegments(base, 2, 1, "quuz"), "Start index > end index did not cause exception!"); }
