getClass
public final Class getClass()Returns the runtime class of an object. That Class object is the object that is locked by static synchronized methods of the represented class. Returns:
the object of type Class that represents the runtime class of the object.也就是得出类或者实体所继承的父类名
如public class getClass { public static void main(String[] args) {
Object b=new Object();
System.out.println(b.getClass());
ObjectTest c=new ObjectTest();
System.out.println(c.getClass());
}
}
输出
class java.lang.Object
class j2.ObjectTest其中ObjectTest是我自己建的一个类

我总感觉不太明白。

可以读取一些配置文件和图片之类的东西
既然已经读了，顺便它也读了一下其它的文件。
这个方法和类信息有什么关系？
