How to develop the ability of mathematicsDr. Fury of the Department of Mathematics!I think we all have this experience: elementary School When you do not know what is the Junior high school mathematics, high School when you can not imagine College mathematics is what. and college students, if you don't focus on math, I'm afraid I don't know what modern mathematics looks like. The following will explain how to learn mathematics from the motivation of l

Date type
The Date type in ECMASCript is built on the Java. util. Date class in java in the early stage. Therefore, the Date type uses the number of milliseconds that elapsed since midnight (0 hours) on January 1, January 1, 1970 in UTC (International Coordination time) to save the Date.

people think that as long as the learning of mathematics, programming things are nothing, but the fact is not so.The fact is this:
Computer science is not mathematics at all, it just borrows very little, very basic mathematics, it is easier than high school math. The so-called "advanced mathematics", in computer science is basically not used.
Computers are more basic tools than math, just like

This article will introduce some main Java classes, such as string, stringbuffer, and math.
Java is a real object-oriented language. Even a simple program must be designed. Java itself also provides many designed classes for us. To use Java for programming flexibly, it is essential to be familiar with these main classes of Java.
String typeAs the name implies, string indicates a string. This class is a String constant class. I believe that anyone who
