The information contained in immutable object is provided at the time of object creation and it is fixed for the lifetime of the object. If you need to modify the object, you can always create a new one that contains the modifications, but the existing won't change. Because immutable ...

In other words coding in JAVA is not possible without object and class. Even the smallest Hello world program requires declaration of class and ...
This output is from the creation of two MCOFIOIB objects. The first part originates from new MCOFIOIB(); and the second part originates from new MCOFIOIB(6);. Each part reveals that object field initializers and object initialization blocks execute before a constructor executes. Furthermore,...
你可以认为class是一个方法的集合,他们接收"this"作为第一个参数.这个包含所有方法的class被载入到内存中并由一个唯一ID标识. 在Java API里这个ID由一个java.lang.Class的实例表示. 你可以通过 MyObject.class 表达式来访问它.
SPI 全称为 Service Provider Interface，是 Java 提供的一种服务发现机制。SPI 的本质是将接口实现类的全限定名配置在文件中，并由服务加载器读取配置文件，加载实现类。这样可以在运行时，动态为接口替换实现类。正因此特性，我们可以很容易的通过 SPI 机制为我们的程序提供拓展功能。SPI 机制在第三方框架中也有所...
