### Question:
VersionHelper { public boolean isSameOrNewer(final VersionHelper ver) { return ver != null && (this.major > ver.major || this.major == ver.major && (this.minor > ver.minor || this.minor == ver.minor && this.release >= ver.release)); } VersionHelper(int major_, int minor_, int release_);  VersionHelper(String ver); String toString(); boolean equals(Object o); int hashCode(); @SuppressWarnings({"UnusedDeclaration"}) boolean majorMinorEquals(final VersionHelper ver); boolean isSameOrNewer(final VersionHelper ver);  }### Answer:
@Test public void isSameOrNewerTest() { final VersionHelper v0 = new VersionHelper(0, 0, 0); final VersionHelper v2_6 = new VersionHelper(2, 6, 0); final VersionHelper v4_1 = new VersionHelper(4, 1, 1); final VersionHelper v4_9 = new VersionHelper(4, 9, 0); final VersionHelper v9_9 = new VersionHelper(9, 9, 9); VersionHelper[] versions = new VersionHelper[]{v0, v2_6, v4_1, v4_9, v9_9}; for (int i = 0; i < versions.length; i++) { for (int j = 0; j < versions.length; j++) { Assert.assertEquals(String.format("expected %s.isSameOrNewer(%s) to be %b", versions[i], versions[j], i >= j), i >= j, versions[i].isSameOrNewer(versions[j])); } } }
