Using Reflection to browse a java class

 


import java.lang.reflect.Constructor;
import java.lang.reflect.Field;
import java.lang.reflect.Method;

public class Main {
  public static void main(String argv[]) throws Exception{
    String className = "String";
    Class c = Class.forName(className);
    Constructor cst[] = c.getDeclaredConstructors();

    // get fields from the Class object
    Field f[] = c.getDeclaredFields();

    // get methods from the Class object
    Method m[] = c.getDeclaredMethods();

    // filling the constructors list box
    for (int i = 0; i < cst.length; i++) {
      System.out.println(cst[i].getName());
    }

    // filling the fields list box
    for (int i = 0; i < f.length; i++) {
      System.out.println(f[i].getName());
    }

    // filling the methods list box
    for (int i = 0; i < m.length; i++) {
      System.out.println(m[i].getName());
    }

  }
