1. Who is more suitable for learning Java?
Is it difficult to learn Java with zero foundation? To answer this question, we should answer it from many aspects. First of all, who is more suitable for learning Java? If it is purely for interest, anyone is suitable. It is like Jiang Ziya 70+ who went out to fight against Zhou. Liu Bang gathered in Pei County to respond to the Chen Sheng & Wu Guang Uprising. He is 47 years old. The age in ancient times is equivalent to our 60s. Now, the painter Qi Baishi became famous at the age of 56 when his painting style suddenly changed.
So, it’s never too late to learn, just like I’ve seen people with different degrees and different goals to learn Java, including junior high school students, doctoral students, corporate executives, etc., so from a learning perspective , The Internet is a very inclusive field, as long as you have a heart and a computer, you can learn at any time.
Some people are curious why PhD students come to study? As I said, everyone has a different purpose. Others do not work for employment, but for scientific research, to improve themselves, and for interest!
2. The age bottleneck
of learning Java If learning Java is used as a knock-on brick in the workplace, and using it as the main skill for earning a living, then you really have to consider the issue of age. If you are still in the Mood for Love, congratulations, in learning ability and memory Among the years with the best ability and understanding, learning Java is the best time, such as college students, college students, technical secondary school students, vocational high school students, and junior high school graduates. Compared with previous studies and future jobs, this period Time can be said to be the most abundant, and energetic, and family pressure is relatively small. At this time, you should study as early as possible!
After the age of 35, people’s memory and learning ability are obviously not as fast as young people due to the influence of the surrounding environment and body. This is the so-called age bottleneck, but now the economy is slightly better and people’s diet and nutrition have improved. So learning Java, the professional bottleneck can be delayed to 38-40 years old.
3. Is interest important in learning Java?
Before entering the industry, you will not know whether interest is important or unimportant. Only after you have studied will you know that interest is still very important. For example, Xiao Li typing code, typing code for a month, it is very painful, typing for three months, feels very novel, typing for a year, feels that when it comes to typing code, feels big head, hot-headed, there is a feeling of wanting to escape, that is called interest Not thick.
If you can bear the programmer’s loneliness and the more common habit of working overtime, and you don’t hate typing code for years, remember, as long as you don’t hate it, it’s all called being interested, because as long as you don’t hate it, you can persist. Afterwards, it will naturally take more time to research and grow better.
Why I said here is not annoying, because taking interest as a career would reduce the concentration of interest, which is inevitable, but as long as it is not annoying, this life can still continue.
4. Is Java tuition expensive?
To be honest, in the training industry, learning Java is more expensive than learning other design and testing courses, not only because it takes a long time to learn, but also because it is more difficult. If you think the tuition is expensive, you can find online courses or Crash course, but the effect depends on your own learning ability and self-control ability.
Many people attend online courses but are absent for various reasons. They feel that everything is okay if there is a screen recording. But how many seriously look at the screen recording and still go to study and ask the teacher questions? It's not impossible, but without the atmosphere of drumming in front of you and gong on the other side, people are easily distracted. Online learning requires strong self-control and comprehension.
5. Do I need to be proficient in English and mathematics to learn Java?
In fact, the English requirements for junior Java programmers are not high. It is almost the same as having a high school level. Of course, if you want to go to a higher level, it is better to reach CET-4 or CET-6 because many technical sources come from the United States. But this is not an overnight job. I have seen many students learn English while learning Java.
As for mathematics, many female programmers are afraid of hearing mathematics. In fact, they don’t have to, because in the field of programming, unless you want to do some scientific research, such as developing some enterprise software, it is enough to have a junior high school mathematics level. Of course you must learn artificial intelligence. , Big data development, etc. It is possible to make up for it at that time.
6. Can beginners learn Java by themselves?
Yes, in any industry, self-study is possible, but self-study is a success, and several conditions must be met. First of all, the self-control and restraint of self-study. For example, if you plan to study on your own for two hours today, you decide to go out happily after a phone call. An excuse of "I am tired today" gives up the study plan for this day. There are a lot of people, oh no, there are many, so people who teach themselves often spend a lot of time and cost.
The 4-month off-the-job class of a training institution usually takes two years for self-study people, and there are still many knowledge points that they don’t understand. When interviewing companies, they tend to be a little unconfident, because self-study people have no idea. In fact, it took four months to go to work and practice. That one and a half years not only allowed you to earn more than enough tuition, but also gained a lot of valuable practical experience.
It's like a person thinking of a poor person, and another person thinking of a rich person. The poor person saves 10,000 yuan if they don’t eat or drink, while the rich eat and drink, invest the remaining 1,000 yuan, and earn back one. Ten thousand yuan, of course, this is an extreme example. For example, your work style is like fishing for three days and two days on the net, and frequent job-hopping. It is difficult to say whether you can earn back your tuition, but I believe that many program kids have perseverance. Good boy paper.
Employment and practice is the best bridge to improve the level of Java technology. At the same initial stage, people who are self-taught in Java are still worried about how to write that section of programming and what functions are there in that tool. In fact, sometimes, some functions of some tools are simply rooted. Children don’t use much in practice, and self-taught people don’t know, but they spend a lot of time on research, and the gains outweigh the losses.
In addition, people who are trained at the same time can also form a technical circle, that is, when you have difficulties, you can also find friends to help. Sometimes, other people's projects develop well, and you can also help. This is called circle effect, and self-learning Java People often lack these "sociality".
If you have any other questions about learning Java, you can communicate with the teacher. After all, it is someone who can guide you on the right path. Even if you don’t go as a programmer, our teacher thinks it is very meaningful and hopes to become a fan. You can help people around you when you come out on the way, and make our lives better and better together!
