### Question:
Neuron implements Serializable, Cloneable { public Weight[] getWeights() { Weight[] weights = new Weight[inputConnections.size()]; for (int i = 0; i < inputConnections.size(); i++) { weights[i] = inputConnections.get(i).getWeight(); } return weights; } Neuron();  Neuron(InputFunction inputFunction, TransferFunction transferFunction); void calculate(); void reset(); void setInput(double input); double getNetInput(); double getOutput(); boolean hasInputConnections(); boolean hasOutputConnectionTo(Neuron toNeuron); boolean hasInputConnectionFrom(Neuron neuron); void addInputConnection(Connection connection); void addInputConnection(Neuron fromNeuron); void addInputConnection(Neuron fromNeuron, double weightVal); final List<Connection> getInputConnections(); final List<Connection> getOutConnections(); void removeInputConnectionFrom(Neuron fromNeuron); void removeOutputConnectionTo(Neuron toNeuron); void removeAllInputConnections(); void removeAllOutputConnections(); void removeAllConnections(); Connection getConnectionFrom(Neuron fromNeuron); void setInputFunction(InputFunction inputFunction); void setTransferFunction(TransferFunction transferFunction); InputFunction getInputFunction(); TransferFunction getTransferFunction(); void setParentLayer(Layer parent); Layer getParentLayer(); Weight[] getWeights(); double getDelta(); void setDelta(double delta); void setOutput(double output); void initializeWeights(double value); String getLabel(); void setLabel(String label); @Override Object clone();  }### Answer:
@Test public void testGetWeightsVector() { List<Weight> weights = Arrays.asList(instance3.getWeights()); assertTrue(weights.contains(testConnection13.getWeight())); assertTrue(weights.contains(testConnection23.getWeight())); assertFalse(weights.contains(testConnection14.getWeight())); }
@Test public void testInitializeWeights_double() { Weight[] w = instance3.getWeights(); assertEquals(.9, w[0].getValue(), .00001); assertEquals(.7, w[1].getValue(), .0001); }
