### Question:
CacheItem implements Serializable { public static boolean checkIfClassVersionApplicable(Object cacheEntry, boolean useStructuredCache) { if (!useStructuredCache && cacheEntry instanceof CacheEntry) { return true; } if (useStructuredCache && cacheEntry instanceof Map) { return true; } return false; } CacheItem();  CacheItem(Object cacheEntry, boolean useStructuredCache); Object getCacheEntry(); String getTargetClassName(); long getTargetClassSerialVersionUID(); boolean isUseStructuredCache(); boolean isTargetClassAndCurrentJvmTargetClassMatch(); static boolean checkIfClassVersionApplicable(Object cacheEntry, boolean useStructuredCache); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString(); static final String STRUCTURED_CACHE_ENTRY_SUBCLASS_KEY; }### Answer:
@Test public void checkIfClassVersionApplicable_useStructuredCache_false() throws Exception { assertThat(CacheItem.checkIfClassVersionApplicable(cacheEntry, false)).isTrue(); }
@Test public void checkIfClassVersionApplicable_useStructuredCache_false_no_CacheEntry() throws Exception { assertThat(CacheItem.checkIfClassVersionApplicable(structuredCacheEntry, false)).isFalse(); }
@Test public void checkIfClassVersionApplicable_useStructuredCache_true() throws Exception { assertThat(CacheItem.checkIfClassVersionApplicable(structuredCacheEntry, true)).isTrue(); }
@Test public void checkIfClassVersionApplicable_useStructuredCache_true_no_Map() throws Exception { assertThat(CacheItem.checkIfClassVersionApplicable(cacheEntry, true)).isFalse(); }
