How do I pass a class as a parameter in Java?

public void foo(Class c){
        try {
            Object ob = c.newInstance();
        } catch (InstantiationException ex) {
            Logger.getLogger(App.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IllegalAccessException ex) {
            Logger.getLogger(App.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

• Here are some good examples on Reflection API

How to invoke method using reflection

 import java.lang.reflect.*;


   public class method2 {
      public int add(int a, int b)
      {
         return a + b;
      }

      public static void main(String args[])
      {
         try {
           Class cls = Class.forName("method2");
           Class partypes[] = new Class[2];
            partypes[0] = Integer.TYPE;
            partypes[1] = Integer.TYPE;
            Method meth = cls.getMethod(
              "add", partypes);
            method2 methobj = new method2();
            Object arglist[] = new Object[2];
            arglist[0] = new Integer(37);
            arglist[1] = new Integer(47);
            Object retobj 
              = meth.invoke(methobj, arglist);
            Integer retval = (Integer)retobj;
            System.out.println(retval.intValue());
         }
         catch (Throwable e) {
            System.err.println(e);
         }
      }
   }
