  To call a method by the string, for example, ?"method"? (and
  here, for example, with the argument list ?( 5, 9 )?),

CallMethod.java

class Example
{
  public static int method( int x, int y ){ return x + y; }

  public static double method( double x, double y )
  { return x + y; }}

public class CallMethod
{
  public static void main( String s[] ) { try
    {
      Class example = Class.forName( "Example" );
      Class[] parameterTypes = new Class[]{ int.class, int.class };
      java.lang.reflect.Method method = example.getMethod( "method", parameterTypes );
      Object[] arguments = new Object[]{ new Integer( 5 ), new Integer( 9 )};
      Object instance = null;
      Integer result =( Integer )method.invoke( instance, arguments );
      System.out.print( result.intValue() ); }
    catch( Exception e ){} }}

System.out

  BTW: Java 7 might get a string switch:
