Notice thefinalize()method – it just prints an empty string to the console.If this method were completely empty, the JVM would treat the object as if it didn’t have a finalizer.Therefore, we need to providefinalize()with an implementation, which does almost nothing in this case. Inside ...

The implementing class may use the javax.annotation.PostConstruct or javax.annotation.PreDestroy annotations on its methods for life cycle event callbacks. The @PostConstruct method is called by the container before the implementing class begins...
调用本地方法时的状态保存在本地方法堆栈中(native method stacks),可能再寄存器或者其他非平台独立的内存中。 Java堆栈有堆栈块(stack frames (or frames))组成。堆栈块包含Java方法调用的状态。当一个线程调用一个方法时,Java虚拟机会将一个新的块压到Java堆栈中,当这个方法运行结束时,Java虚拟机会将对应的块弹...
/*** Close the stream when garbage is collected.*/ protected void finalize() { try { file.close(); } catch (Exception e) { } } Thisfinalizemethod will be invoked when the object is about to be garbage collected, which means that the object must shut itself down in an orderly fashion...

Finally, choose the time zone and the root password to finalize the system configuration. Note: Only one network interface card (NIC) can be configured using the system configuration tool; therefore, the public interface ilb_1 will be configured later by logging in to the zone. Once you ha...
