### Question:
DataVersion { public static boolean isCompatible(String dataVersion) { int dataVer = parseVersion(dataVersion); if (dataVer < VERSION_LOWEST) { return false; } if (VERSION >= dataVer) { return true; } else { return false; } }  static String getCurrentVersion(); static boolean isCompatible(String dataVersion);  }### Answer:
@Test public void isCompatibleTest() { assertTrue(DataVersion.isCompatible(DataVersion.getCurrentVersion())); assertFalse(DataVersion.isCompatible("tbschedule-3.2.13")); assertFalse(DataVersion.isCompatible("tbschedule-3.2.11")); assertFalse(DataVersion.isCompatible("tbschedule-4.0.0")); assertFalse(DataVersion.isCompatible("tbschedule-4.0.2")); assertFalse(DataVersion.isCompatible("tbschedule-4.0.2.asdfs")); assertFalse(DataVersion.isCompatible("tbschedule-4.1.0-asdfs")); assertTrue(DataVersion.isCompatible("tbschedule-4.1.0")); }
