Java getClass()方法

先看代码执行结果：

import java.util.Date;

public class SuperClassTestDemo extends Date{

private static final long serialVersionUID = 890185079756933430L;

public static void main(String[] args) {
new SuperClassTestDemo().test();
}

public void test(){
System.out.println(super.getClass().getName());
System.out.println(this.getClass().getName());
System.out.println(getClass().getSuperclass().getName());
}

}

执行输出结果：

[align=left]SuperClassTestDemo[/align]
[align=left]SuperClassTestDemo[/align]

[align=left]java.util.Date[/align]

解释：

测试getClass()方法，此方法为final修饰

public final Class<?> getClass()：

Returns the runtime class of this Object. The returned Class object is the object that is locked by static synchronized methods of the represented class.
