一般程序都很少用到反射，下面是一個簡單的用到反射的例子 import java.lang.reflect.*; class loadclass public class reflecttest { static { System.out. } public static void staicMethod() { System.out.println("staticMethod Called"); } public void instanceMethod() { System.out.println("instanceMethod Called"); } public static void main(String[] args) { Class c=reflecttest.class; try { Method method = c.getMethod("staicMethod", null); method.invoke(c,null); method.invoke(c.newInstance(),null);
method=c.getMethod("instanceMethod",null); //method.invoke(c,null); //將拋出異常IllegalArgumentException：object is not an instance of declar ing class method.invoke(c.newInstance(),null); } catch (Exception ex) { ex.printStackTrace(); } } }
