### Question:
AssetPropertyElementBase implements Serializable { public int hashCode() { return hashCode; } AssetPropertyElementBase();  AssetPropertyElementBase(AssetPropertyElementBase template); int hashCode(); @Override boolean equals(Object object); @Override String toString();  }### Answer:
@Test public void testHashCode() { AssetPropertyElementBase testTemplate = new MockAssetPropertyElement(); assertTrue(testTemplate.hashCode() != 0); AssetPropertyElementBase testObject = new MockAssetPropertyElement(testTemplate); assertTrue(testObject.hashCode() != 0); assertTrue(testObject.hashCode() == testTemplate.hashCode()); }
