The next example uses Java's reflection capabilities to obtain the public methods of a
class. The program begins by instantiating class A. The getClass( ) method is applied to
this object reference, and it returns the Class object for class A. The getDeclaredMethods( )
method returns an array of Method objects that describe only the methods declared by
this class. Methods inherited from superclasses such as Object are not included.
Each element of the methods array is then processed. The getModifiers( ) method returns
an int containing flags that describe which modifiers apply for this element. The Modifier
class provides a set of methods, shown in Table 27-5, that can be used to examine this value.
For example, the static method isPublic( ) returns true if its argument includes the public
modifier. Otherwise, it returns false. In the following program, if the method supports
public access, its name is obtained by the getName( ) method and is then printed.
// Show public methods.
import java.lang.reflect.*;

public static void main(String args[]) {
