Class Reflection: Showing methods

[Java Tip]

Code:

import java.awt.Polygon;
import java.lang.reflect.Method;

public class SampleMethod {

  public static void main(String[] args) {
    Polygon p = new Polygon();
    showMethods(p);
  }

  static void showMethods(Object o) {
    Class c = o.getClass();
    Method[] theMethods = c.getMethods();
    for (int i = 0; i < theMethods.length; i++) {
      String methodString = theMethods[i].getName();
      System.out.println("Name: " + methodString);
      String returnString = theMethods[i].getReturnType().getName();
      System.out.println("   Return Type: " + returnString);
      Class[] parameterTypes = theMethods[i].getParameterTypes();
      System.out.print("   Parameter Types:");
      for (int k = 0; k < parameterTypes.length; k++) {
        String parameterString = parameterTypes[k].getName();
        System.out.print(" " + parameterString);
      }
      System.out.println();
    }
  }
}
