### Question:
NumberSequence extends SimpleSymbol { @Override public String getValue (String name) { checkName (name); return Integer.toString (++mIntValue); } NumberSequence(String name, Scope scope, int value); @Override String getValue(String name); @Override void setValue(String name, String value);  }### Answer:
@Test public void testGetValue () { assertEquals (Integer.toString (INITIAL_VALUE), mSequence.getValue (NAME)); assertEquals (Integer.toString (INITIAL_VALUE + 1), mSequence.getValue (NAME)); }
