Chapter 88 The law is not responsible, I am responsible 24

"Kid, just watch."

Jiang Lan pulled out a chair and sat on it.

"Exceptions in Java are divided into two categories: Errors and Exceptions. Errors are generally all errors during compilation or system errors, which come from the virtual machine itself. Such errors cannot be handled. Exceptions are exceptions that can be handled by the program itself, which means that there is a problem with the program itself, and the exception can be handled."

Jiang Lan opened the running code background, "It is very difficult to find bugs with the naked eye. At this time, we should look for the error log."

She clicked on the error log, which was filled with dense English.

"As an excellent programmer, you should know basic English, right?"

Many people at the scene lowered their heads. Many boys who are good at science and engineering have a common problem, which is that they are not good at one subject.

Especially in English, they are more or less not very good.

Jiang Lan turned his head and saw what level they were at. He shook his head speechlessly.

"Okay, if you can't understand the error log, you can actually use tools to find bugs. The IDEA integrated development tool and the Eclipse development tool both have built-in tools for debugging bugs, but the speed is a bit slow."

"Mr. Jiang, what you said is all theory. It's just like talking in vain."

"That's right, you just talk without practicing."

Jiang Lan looked at the two people with a smile, "What are your names?"

"..." The two outspoken birds felt dangerous and immediately dared not speak anymore.

"I'll remind you that you haven't seen the results yet, so don't rush to express your superficial opinions. This will only make you look more stupid."

Jiang Lan exited the previously running code interface. "I'm too lazy to modify such a simple program. Today I'll show you what a real tool for finding bugs is. If anyone's computer is not used to test bugs, lend me one."

"I... I have one!" A programmer wearing glasses handed his computer to Jiang Lan.

"My computer was just received not long ago, and it's still brand new."

"Very good."

Jiang Lan opened the relevant interface and concentrated on programming.

This time she wanted to make a small tool specifically for finding bugs, which would save a lot of time.

Fifteen minutes passed, and a dozen people in the office gathered behind Jiang Lan, not daring to breathe, staring at the lines of code on the computer screen.

After 25 minutes, the entire program was written.

Jiang Lan checked it once, found no problem, and stood up.

"It's done, use the little tool I made to find the bug, it will definitely be faster than what you are using now, if you don't believe me, you can try it yourself."

A group of programmers surrounded them, and instantly squeezed Jiang Lan and Ye Chengxuan out.

Ye Chengxuan was happy to see such a slap in the face scene. The more capable Jiang Lan was, the more it proved that his choice was not wrong.

"Director Jiang, are you interested in visiting other departments? You just went to the Technology Department. Ye's has many departments besides the Technology Department."

"Ah? Forget about the Technology Department." Jiang Lan was stunned for a moment, "Other departments have anything to do with me?"

"Ahem, of course... After all, each department needs the guidance of the Technology Department to see if there is anything that can be improved."

"Okay."

Since he was paid by the department, Jiang Lan was still very cooperative.

Ye Chengxuan took Jiang Lan to various important departments of the company to observe their use of computers and programs. As a result, Jiang Lan, the newcomer, really found a lot of problems.

Large companies always have the problem of complicated programs, and Ye's is no exception.

From the perspective of a programmer, Jiang Lan gave Ye Chengxuan some optimization suggestions.

“Ye Technology’s main products are various operating systems. For example, hospitals, banks and other institutions with relatively large traffic will mostly choose our Ye’s operating system.”

“It turns out that it’s a rubbish system made by you guys.”

Jiang Lan remembered that the original owner had gone to the hospital for treatment, but the program got stuck, causing her to wait 10 more minutes.

Ye Chengxuan swallowed the words that were about to come out of his mouth and explained:

"The program that you think is rubbish is actually far better than 99% of the systems on the market. And even if we had some minor flaws before, you can make up for it after you come, right?"

Jiang Lan sighed: "This is the first time I know that this kind of program can sell for a lot of money. I thought that the Internet technology companies that make money on the market are all doing shopping platforms, chat software, games and the like."

"What you said is relatively speaking, the investment cost is very high, and the market saturation is also very high. Like our Ye's, we are the type of people who make a fortune in silence. We specialize in customizing software and operating systems for large enterprises. A system starts at at least one million."

"Awesome!" Jiang Lan admired sincerely.

"Businessmen think differently. Have you ever thought about making something more advanced? Artificial intelligence or something like that?"

"Artificial intelligence is indeed a market, and we at Ye's are also very optimistic about it."

Ye Chengxuan smiled, with a bit of lightness in his tone, "After Director Jiang came, I think Ye's may be able to get a share of this market."

Jiang Lan thought to himself, this Ye Chengxuan is really an old fox, who will climb up the ladder.

"Mr. Ye, you are too confident in me."

"Director Jiang, have you noticed a very obvious characteristic of yourself?"

Jiang Lan was puzzled and asked him, "What characteristic?"

"It's just that I am very confident. Of course, this is not a derogatory word."

"What's wrong?" Isn't confidence a good thing?

Ye Chengxuan smiled, "It's a good thing. Seeing Director Jiang's confidence makes people feel that nothing in this world is difficult."

"I don't know whether you are praising me or insulting me."

Jiang Lan smiled, "But I think artificial intelligence can be done, and there is a huge market."

"There are already some on the market, such as Mimi Elf and Ade."

"Too superficial, it's just inputting some programs and making some specific reactions."

Jiang Lan, who was used to the artificial intelligence system of the star, was a little dissatisfied with these stereotyped things.

"Mr. Ye, there is still a long way to go."

"Director Jiang, don't you consider studying artificial intelligence together? Isn't it more interesting and meaningful than aquaculture? I can form a team and give it to you to manage. What do you think?"

Good boy, it turns out that you are waiting for me here.

Jiang Lan shook his head and started to change the subject.

"Aquaculture is so great. Every day I can watch cute crabs crawling around and cute fish swimming around. It's much more interesting than staying in the office all day, writing programs with my eyes closed. Don't try to fool me. I'm the future aquaculture boss."

Ye Chengxuan was not discouraged even though his trick failed.

He believed that Jiang Lan would one day turn to the light. After all, aquaculture and research and development are not easy tasks.

"Then I'll wait and see."

Jiang Lan and Ye Chengxuan looked at each other, their eyes full of fighting fire.

Ye's employees secretly took a photo of the two looking at each other and posted it in the group.
