The class class for Java

1  Packagetest;2 Importjava.util.Date;3  Public classSuperTestextendsdate{4     Private Static Final LongSerialversionuid = 1L; 5     Private voidTest () {6System.out.println (Super. GetClass (). GetName ()); 7     } 8       9      Public Static voidMain (String[]args) {Ten        NewSuperTest (). Test (); One     }  A}

The output is: test. SuperTest

Analysis:super.getClass() 得到的依然是runtime当前类，若要得到真正的父类，需要用super.getClass().getSuperclass()

虽然这里写的是 super ，但其实用 this 也一样The class class of Java is the basis of the Java reflection mechanism, and we can obtain information about a class through class classes. Java.lang.Class is a special class that encapsulates information that is loaded into a class (including classes and interfaces) in the JVM. When a class or interface is loaded into the JVM, it produces a Java.lang.Class object associated with it, which can be accessed through this class object for the details of the loaded class.
