一、通过一个对象获得完整的包名和类名

package net.xsoftlab.baike;
public class TestReflect {
    public static void main(String[] args) throws Exception {
        TestReflect testReflect = new TestReflect();
        System.out.println(testReflect.getClass().getName());
        // 结果 net.xsoftlab.baike.TestReflect
    }
}

 

二、实例化Class类对象

package net.xsoftlab.baike;
public class TestReflect {
    public static void main(String[] args) throws Exception {
        Class<?> class1 = null;
        Class<?> class2 = null;
        Class<?> class3 = null;
        // 一般采用这种形式
        class1 = Class.forName("net.xsoftlab.baike.TestReflect");
        class2 = new TestReflect().getClass();
        class3 = TestReflect.class;
        System.out.println("类名称   " + class1.getName());
        System.out.println("类名称   " + class2.getName());
        System.out.println("类名称   " + class3.getName());
    }
}
