import java.lang.reflect.Method; import java.lang.reflect.InvocationTargetException; /** * Created by IntelliJ IDEA. * File: TestRef.java * User: leizhimin * Date: 2008-1-28 14:48:44 */ public class TestRef {     /**     *通过类地址来调用     */    public void test() {try {Class clazz = Class.forName("com.xlwz.wizard.impl.ChooseJdkprocess");Method getRootPath = clazz.getDeclaredMethod("getRootPath");System.out.println(getRootPath.invoke(clazz.newInstance()));} catch (Exception e) {}}    public static void main(String args[]) throws NoSuchMethodException, IllegalAccessException, InvocationTargetException {         Foo foo = new Foo("这个一个Foo对象！");         Class clazz = foo.getClass();         Method m1 = clazz.getDeclaredMethod("outInfo");         Method m2 = clazz.getDeclaredMethod("setMsg", String.class);         Method m3 = clazz.getDeclaredMethod("getMsg");         m1.invoke(foo);         m2.invoke(foo, "重新设置msg信息！");         String msg = (String) m3.invoke(foo);         System.out.println(msg);     } } class Foo {     private String msg;     public Foo(String msg) {         this.msg = msg;     }     public void setMsg(String msg) {         this.msg = msg;     }     public String getMsg() {         return msg;     }     public void outInfo() {         System.out.println("这是测试Java反射的测试类");     } }

调用静态方法

public static void Test(){System.out.println("123");}public static void main(String[] args) throws Exception {Class c; c = Class.forName("link.Test3"); Method m = c.getMethod("Test"); m.invoke(c); }

控制台输出结果：

这是测试Java反射的测试类 重新设置msg信息！ Process finished with exit code 0
