老生常谈Java动态编译(必看篇)

public class OfficeBetter { public static void main(String[] args) throws InstantiationException, IllegalAccessException {  try {   //动态加载类，在运行时刻加载   Class c =Class.forName(args[0]);   //通过类类型，创建该类对象   OfficeAble oa =(OfficeAble)c.newInstance();   oa.start();  } catch (ClassNotFoundException e) {   e.printStackTrace();  }   } }

 public interface OfficeAble {  public void start(); } 

public class Word implements OfficeAble{ public void start() {  System.out.println("word....starts..."); } }
