Yesterday, I logged in boss Zhipin, which has not been used for a long time, to check the market. In one day, MORE than 20 companies have invited me to interview. First, I would like to talk to you about the birth and current situation of Java.

Legend has it that in the 1990s, a company called Sun set up a project group to focus on embedded computer applications in home appliances. The group’s leaders, finding C++ too complex and bulky, took matters into their own hands and developed an object-oriented language called Oak. When they applied for the trademark, they found it had already been registered, so they thought of a series of names. Finally, while drinking a Java coffee, they accidentally mentioned Java, which was unanimously approved. If this happened in the northeast of our country, I would like to believe that the Java will be called “erguotou”! It’s a good wine, but it’s a little on the top!

The above legend is pure fact, Java is magically born this way. This article will talk with you, now the Java river’s lake is wrong. If there is a place where there are rivers and lakes, then the more people the greater the lake ah! In the world of programmers, Java claims to be the second “lake”. No one can claim to be the first “lake”. Java programmers are undoubtedly the largest group of modern programmers. Why are so many people doing Java? In my humble opinion, there are the following reasons:

With the rapid development of the Internet in modern times, the demand for Java programmers is increasing day by day. Just open a recruitment software, Java-related positions must be the most in programmer positions, and the demand for Java positions in major companies is also the largest. Java programmers’ pay varies, but overall, it’s good, so there’s a lot of learning going on.

The entry threshold of Java is not too high, specialized subject can, undergraduate course can, graduate student can also, record of formal schooling size all eat. The man who is trained in iron can learn, the soft sister who is engaged in finance can also get started, and there are many people who change careers across major.

So much for the Java industry background. There is an old saying that “the gun should be hard, but the mouth should be soft”. As a programmer, the most important gun is his own technical level. In the following articles, I will start from scratch to talk about Java technology.
