A simple example is given below, and if the exception is not caught, the exception is thrown and the program stops running:Print (1/0)Print (1/1)======= console output =======Traceback (most recent call last) :"D:\workspace\ eclipse_neon\python-hello\src\test.py" in 0ZeroDivisionError : Divis

compatibility with Java.Another thing that sometimes leads to denial is that Scala contains both traits technology and class technology. It is thought that a neat design should be only using traits technology. There are some neat designs that use only traits to abandon class concepts, but we have not done so. Because we want to keep the interoperability with Java from these two aspects. We want a way to make it easy for

Java library is clearly organized and disciplined, taking full account of practical applications. For example, a widely available ToStringJava implements class objects for each class, so the dynamic type becomes easy and imaginative. But it also brings about efficiency issues. If the defined class has only a few objects, the cost is too high, but if the object is batch, and the RTTI can bring great advantages, it can be used. It is best to allow prog

Why can Java cross-platform?Applications written in the Java language can be run on different system platforms, and programs written in the C + + language can only run on Windows systems and will not work on Linux. Why is Java so resourceful? Principle: Java has a separate parser that resolves

1. DescriptionAs a programmer, we often have to do one thing: Get a log file and find out the information you want. This article summarizes what tools I used to analyze the log file to get the information I want, my work environment in recent years is the server on Linux, the work machine is windows, so I use the tool is mainly Linux on some command-line tools, Of course they can also be used on Windows, specifically see the following tool.First of al

In the study of Java often encounter some words, but the general time is not very concerned about the meaning of the word, but can understand what this tool or framework can do.

an abstract class and an interface?(1) Abstract classes need to be inherited, and can only be inherited. Interface needs to be implemented, and can be implemented more, that is, to implement multiple interfaces(2) Abstract classes can be defined abstract methods and non-abstract methods, subclass inheritance can directly invoke non-abstract methods, the interface can only define abstract methods (that is, all of the interfaces are not implemented methods), subclasses must implement their method
