### Question:
UInt64 extends Message { @Override public UInt64 clone() { return new UInt64(this.data); } UInt64();  UInt64(long data); long getData(); @Override UInt64 clone(); static UInt64 fromJsonString(java.lang.String jsonString); static UInt64 fromMessage(Message m); static UInt64 fromJsonObject(JsonObject jsonObject); static final java.lang.String FIELD_DATA; static final java.lang.String TYPE; }### Answer:
@Test public void testClone() { UInt64 clone = i1.clone(); assertEquals(i1.toString(), clone.toString()); assertEquals(i1.toJsonObject(), clone.toJsonObject()); assertEquals(i1.getMessageType(), clone.getMessageType()); assertEquals(i1.getData(), clone.getData()); assertNotSame(i1, clone); assertNotSame(i1.toString(), clone.toString()); assertNotSame(i1.toJsonObject(), clone.toJsonObject()); }
