How important is a readable code to a programmer
People assume that writing code that any programmer can read and understand is an inherent skill of software developers. In fact, only 20% of programmers have this ability. The code you write must not only be understood by machines, but also by humans. In software development, code quality should be the top priority of every developer. Therefore, delivering high-quality working code should be every developer's primary goal throughout the development process.
What is code quality?
Code quality loosely defines how useful and maintainable the code is over an extended period of time. More formally, code quality consists of a set of distinct attributes and requirements that are dictated by your business and determine their importance. This means that the code that can be discarded tomorrow is low-quality code. Conversely, code that can be passed from one product to another, developed further, and even open-sourced once its value has been established is high-quality code.
Therefore, a code that can be called "good" quality should at least meet the following requirements
should be able to do what it's supposed to do.
A consistent style should be followed.
Should be easy to understand.
Should have good documentation.
It should be possible to test.
Why should you care about code quality?
For example, everyone loves to read a good story. A good story is one that is easy to read and understand for an ordinary person who does not understand literature. Great authors write books with compelling stories that are easy to read and understand. Just as a writer's work must be easy to read and understand, so should a software developer's code. After all, code is, in some ways, the story developers write.
It can be tempting to compromise on code quality to meet project deadlines, but if you want your code to survive in the long run, you have to write code that meets all code quality standards. The quality of your code defines what kind of developer you are. Maybe you are a really good programmer and can write 100 lines of code in 10 minutes, but you need to think about your code from a maintainability point of view. Can you make sure whoever maintains the project or your colleagues understand your genius idea?
Also, high-quality codes speed up the long-term development of software because they can be reused and developers don't have to spend as much time fixing old bugs and polishing the code. High-quality code also makes it easier for new project members to join the project. All of this in turn reduces technical debt.
How to improve code quality?
Now that we are convinced that code quality is an integral part of software development, I am sure you must be wondering how to improve code quality? So I've listed below some ways you can improve your code quality:
Establish version control and code review mechanisms.
Follow a continuous integration process.
Develop and follow coding standards.
Run the tests.
Parsing error.
Measure code quality.
The above methods to improve code quality are relatively cumbersome and complicated. With the development of AI technology, many AI development tools have integrated the above points and are committed to ensuring code quality on the basis of improving development efficiency. Taking the FuncGPT (wit function) launched by SoFlu software robot, which focuses on AI to generate Java functions, as an example, let's look at a specific development case:
Faced with a task management system that includes when tasks are created and when they are due. Now you need to use Java functions to realize the function of calculating the remaining time of the task, so as to remind the user how much time is left to complete the task.
Function function: Calculate the difference in days between two dates (return a string)
Parameter 1: parameter name: startTime; parameter type: Date; parameter description: start time
Parameter 2: parameter name: endTime; parameter type: Date; parameter description: end time
Parameter 3: Parameter name: format; Parameter type: String; Parameter description: formatting characters, for example: day, hour, minute
return value: String
Try it out by using FuncGPT (Hui Function), which focuses on AI-generated Java functions launched by SoFlu software robot. In just 24 seconds, FuncGPT (Hui Function) automatically generates the following code:
// 类名：DateUtils
// 函数名：calculateDateDifference
// 函数功能：计算两个日期相差天数
// POM依赖包：
// <dependency>
// <groupId>joda-time</groupId>
// <artifactId>joda-time</artifactId>
// <version>2.10.10</version>
// </dependency>
import org.joda.time.DateTime;
import org.joda.time.Days;
public class DateUtils {
/**
* 计算两个日期相差天数
* @param startTime 开始时间
* @param endTime 结束时间
* @return 相差天数字符串
*/
public static String calculateDateDifference(DateTime startTime, DateTime endTime, String format) {
Days days = Days.daysBetween(startTime, endTime); // 使用Joda-Time计算相差天数
int difference = days.getDays();
String result;
switch (format) {
case "天":
result = difference + "天";
break;
case "时":
result = difference * 24 + "小时";
break;
case "分":
result = difference * 24 * 60 + "分钟";
break;
default:
throw new IllegalArgumentException("Invalid format"); // 如果格式不合法，抛出异常
}
return result;
}
}
// 函数示例
// 计算两个日期相差天数示例
// 入参：startTime，开始时间，类型为DateTime；endTime，结束时间，类型为DateTime；format，格式化字符，类型为String
// 出参：result，相差天数字符串
// 调用示例：
// DateTime startTime = new DateTime(2022, 1, 1, 0, 0); // 创建开始时间对象
// DateTime endTime = new DateTime(2022, 1, 5, 0, 0); // 创建结束时间对象
// String result = DateUtils.calculateDateDifference(startTime, endTime, "天");
// System.out.println(result);
// 输出结果：例如，计算2022年1月1日和2022年1月5日相差天数为：4
// 则输出结果为：4天From the above code, we can easily see that
The code generated by FuncGPT (intelligent function) is more readable, and the naming and annotation specifications, class names and function names can clearly express the function of the code. Moreover, the implementation method is simple and intuitive. By using the method provided by the Joda-Time date and time library, the calculation logic of the number of days between dates is simplified, and more accurate parameter types are provided.
Since FuncGPT (intelligent function) is trained through code writing best practices and large-scale machine joint training, it has an in-depth study and understanding of Java grammar, so the generated function code is of high quality, conforms to industry standards, and avoids common code errors and low cost. effect.
Specifically, because:
1. FuncGPT ( intelligent function) has powerful natural language processing capabilities, can accurately understand user descriptions and requirements for functions, and reduces the cost of development and communication and the difficulty of understanding.
2. The code generated by FuncGPT (intelligent function) has been accurately understood and trained, including clear code comments, which reduces bugs caused by negligence and grammatical errors, and improves software quality and stability.
3. The code generated by FuncGPT follows the best practices, tends to use good code structure, avoids too long functions and excessive nesting, and teaches developers the industry's excellent coding style and design patterns, thereby improving the overall The coding level of the team.
