How to use JavaScript to obtain browser Information
Window has a navigator object to let us know all the information about the browser. We can use a series of API functions to know the information about the browser.
The JavaScript code is as follows:
Function message () {txt = "
We can use this function to notify the user browser whether to update the browser, and also to help the user know the browser information.
Basic information of various browsers

One. HIVE StreamingIn hive, when you need to implement a function that is not possible with a function in hive, you can use streaming to implement it. The principle can be understood as: using language other than the HQL statement, such as Python, Shell to implement these functions, while cooperating with the HQL statement, to achieve special functions.Two.

a platform-independent environment, Java is a bit slower than native code. However, smart compilers, well-modulated interpreters and instant byte-code compilers canKeep Java's performance close to the local code without sacrificing portability.//==============================================As a learning Java person, first of all we need to understand what Java is, what Java can do, and the historical background of Java, only when we understand the basics of Java, we learn Java to do less.Java

Java, an object-oriented programming language that can compose Cross-platform applications, was developed in the early 1990 by James Goslin (James Gosling) of Yu Shenyang (Sun Microsystems) company. It was originally named Oak, which aims to address the control and communication problems of household appliances such as televisions, telephones, alarms, toasters, and other small-system programming languages such as household appliances. Sun gave up the
