    e118.  
    Getting the Methods of a Class Object</h3>

There are three ways of obtaining a <code>Method</code> object from a
<code>Class</code> object.


<pre>
    Class cls = <font color="#0066ff"><i>java.lang.String.class</i></font>;
    
    // By obtaining a list of all declared methods.
    Method[] methods = cls.getDeclaredMethods();
    
    // By obtaining a list of all public methods, both declared and inherited.
    methods = cls.getMethods();
    for (int i=0; i&lt;methods.length; i++) {
        Class returnType = methods[i].getReturnType();
        Class[] paramTypes = methods[i].getParameterTypes();
        <font color="#0066ff"><i>process</i></font>(methods[i]);
    }
    
    // By obtaining a particular Method object.
    // This example retrieves String.substring(int).
    try {
        Method method = cls.getMethod(<font color="#0066ff"><i>"substring"</i></font>, new Class[] {<font color="#0066ff"><i>int.class</i></font>});
        <font color="#0066ff"><i>process</i></font>(method);
    } catch (NoSuchMethodException e) {
    }
