### Question:
Last extends Activation { public Last() { this(1); } Last();  Last(int numberOfRules);  Last(int numberOfRules, double threshold); @Override String parameters(); @Override void configure(String parameters); @Override void activate(RuleBlock ruleBlock); int getNumberOfRules(); void setNumberOfRules(int numberOfRules); double getThreshold(); void setThreshold(double threshold); @Override Last clone();  }### Answer:
@Test public void testLast() { Engine engine = Console.mamdani(); InputVariable ambient = engine.getInputVariable(0); ambient.setValue(0.7); RuleBlock ruleBlock = engine.getRuleBlock(0); ruleBlock.setActivation(new Last(1)); engine.process(); List<Rule> rules = engine.getRuleBlock(0).getRules(); Assert.assertThat("First rule was not fired", rules.get(0).isTriggered(), is(false)); Assert.assertThat("Second rule was not fired", rules.get(1).isTriggered(), is(false)); Assert.assertThat("Third rule was fired", rules.get(2).isTriggered(), is(true)); }
