Class类对象的三种实例化方法

class X {

}

public class GetClassDemo01 {
    public static void main(String[] args) {
        X x = new X();
        System.out.println(x.getClass().getName());
       
        Class<?> c1=null;
        Class<?> c2=null;
        Class<?> c3=null;
        try {
            c1=Class.forName("Charp17Reflact.X");
        } catch (Exception e) {
            e.printStackTrace();
        }
        c2=new X().getClass();
        c3=X.class;
        System.err.println(c1.getName());
        System.err.println(c2.getName());
        System.err.println(c3.getName());
    }
}
