<center><h3> Jave example explained </h3></center>

This is a simple java code used to load a fuzzy inference system (FIS), this code available at net.sourceforge.jFuzzyLogic.TestTipper.java<p>

<ul>
	<li>First load an FCL file, using <code>FIS.load(fileName)</code> function.<br>
		<table border=0 bgcolor=#ccfccc><tr><td>
<pre>String fileName = "fcl/tipper.fcl";
FIS fis = FIS.load(fileName,true);
</pre></td></tr></table><p>

	<li> When an error is detected during <code>FIS.load()</code>, a <code>null</code> object is returned.
		<table border=0 bgcolor=#ccfccc><tr><td>
<pre>if( fis == null ) { // Error while loading?
	System.err.println("Can't load file: '" + fileName + "'");
	return;
}
</pre></td></tr></table>
		<p>

	<li> Now we can plot the FIS. Actually, we plot each Variable in the FUNCTION_BLOCK (and each LinguisticTerm in each Variable). This might only be usefull when you are debugging your code.
		<table border=0 bgcolor=#ccfccc><tr><td><pre> fis.chart(); </pre></td></tr></table>
		<p>
		And we get the following images:<p>
		<center>
		<img src=images/service.png><p>
		<img src=images/food.png><p>
		<img src=images/tip.png><p>
		</center>

	<li> Now we use the FIS. We start by setting FIS' inputs
		<table border=0 bgcolor=#ccfccc><tr><td>
<pre>fis.setVariable("service", 3);
fis.setVariable("food", 7);
</pre></td></tr></table>
		<p>

	<li> And we run the system
		<table border=0 bgcolor=#ccfccc><tr><td><pre>fis.evaluate();</pre></td></tr></table>
		<p>
		
	<li> If we want to know the system's output (in this case there's only one output variable 'tip')
		<table border=0 bgcolor=#ccfccc><tr><td><pre>fis.getVariable("tip").getLatestDefuzzifiedValue();</pre></td></tr></table>
		<p>

	<li> We can also plot output's defuzzifier (probably only during debuging)
		<table border=0 bgcolor=#ccfccc><tr><td><pre>fis.getVariable("tip").chartDefuzzifier(true);</pre></td></tr></table>
		<p>
		<center>
		<img src=images/tip_out.png><p>
		</center>

	<li> And, of course, we can print the FIS 
		<table border=0 bgcolor=#ccfccc><tr><td><pre>System.out.println(fis);</pre></td></tr></table>
		<p>
</ul>
