Let's discuss the interface in this section.Before we had talked about abstract classes, he had taken the first step of abstraction, abstracted some methods, and then implemented them in subclasses, but he was not completely abstract.And the interface, is the further abstraction, it is completely not implemented in the method, so the method is implemented in the implementation of the class.1. ConceptInterface: Just like a protocol between a class and a class, you only need to know an interface t
Any scientific method is not absolutely accurate. Therefore, many factors may cause the measured value to deviate from the actual geological value in the oil logging. In many cases, it also needs to be corrected using the actual strata. What are the factors that affect logging?
1. Influence of Logging Instrument
A logging instrument is a metering tool. Therefore, it must be accurate, and the error must be

Usi
The current U disk capacity is getting bigger and bigger. Do you want to transform your U disk into an "instrument U disk "? No matter where your device goes, you just need to insert the USB flash drive on the instrument into your computer, you can easily read the running data of your device. This allows devices to synchronize data with their own computers. In fact, these ideas are not difficult to implemen

When a thing is very practical, many Chinese people will borrow this concept to do it, Baidu, QQ, Taobao i
.7.7 Upward transformationIn Java inheritance, the relationship between the base class and the exported class can be summed up as "The export class is a type of the base class." For example, there is a base class for the instrument named Instrument and an export class named Wind. Because inheritance ensures that all methods in the base class are equally valid in the exported class, all the information that
Our project is a Java EE project that involves the SPRING,HIBERNATE,STRUTS,EJB. Deployed on WebSphere, the local development environment is IBM RAD. The project team has developed a test framework based on JUnit, which can be used to invoke test classes through JSP to derive test results. The drawback is that the framework does not have code coverage. So we decided to introduce Cobertura.
Analyzing the Bulid.xml of the Cobertura example, we can break it down into several steps:
1. Compile the

general type, it is always safe. that is to say, the export class is a superset of the base class. it may contain more methods than the base class, but it has at least all the methods contained in the base class.In the process of upward transformation, the only thing that may happen in the class interface is to lose methods rather than get them. this is why the compiler still allows upward transformation without "explicitly indicating transformation" or "without specifying a special mark for tr
SuperLink network tester is a multi-link, multi-procedure testing instrument. It is mainly used to test and analyze various communication protocols of the telephone network, ISDN network, GSM network, and CDMA network. At the same time, the powerful data statistics function of this instrument also facilitates the daily maintenance of the equipment.
One platform supports testing of multiple networks and thei
I. Music
Indian music has at least 3000 years of history. The song in the book 'pyriverid', which came out around 1500 BC, can be seen as the earliest lyrics. The moveda is a song set of ancient times, designed for the priests to sing at sacrifices. "Momo" refers to the tune. Therefore, like drama, Indian music may also originate from religious sacrifices.Indians regard music as a kind of lofty art that can make the soul of a human exclusive world and sublimate to the spiritual world.
