Examples of using Chinese variable names in Java programming

Application cases of Chinese variable names in Java programming

In recent years, with the rise of Chinese character programming, the use of Chinese variable names has become more and more common in Java programming. . Compared with traditional English variable names, Chinese variable names can express the meaning of the code more intuitively and reduce the difficulty of understanding and maintaining the code. This article will introduce the application of Chinese variable names in Java programming through specific cases and code examples.

Case 1: Student Performance Management System

The student performance management system is a common application scenario. We show its application in the code by using Chinese variable names.

public class 学生成绩管理系统 {
    public static void main(String[] args) {
        // 定义变量
        int 学号 = 123456;
        String 姓名 = "张三";
        int 语文成绩 = 90;
        int 数学成绩 = 80;

        // 输出学生信息和总分
        System.out.println("学号：" + 学号);
        System.out.println("姓名：" + 姓名);
        System.out.println("语文成绩：" + 语文成绩);
        System.out.println("数学成绩：" + 数学成绩);

        int 总分 = 语文成绩 + 数学成绩;
        System.out.println("总分：" + 总分);
    }
}

By using Chinese variable names, we can intuitively understand the meaning and function of the code. In this case, the Chinese variable name directly represents the student's student number, name, and scores in Chinese and mathematics. This makes it easier to understand and maintain, whether writing or reading code.

Case 2: Shopping cart function

The shopping cart function is one of the common functions in an e-commerce application. In this case, we use Chinese variable names to display product information and shopping cart operations.

public class 购物车功能 {
    public static void main(String[] args) {
        // 定义商品信息
        String 商品名称 = "手机";
        double 商品价格 = 2999.99;
        int 商品数量 = 1;
        double 商品总价 = 商品价格 * 商品数量;

        // 输出商品信息
        System.out.println("商品名称：" + 商品名称);
        System.out.println("商品价格：" + 商品价格 + "元");
        System.out.println("商品数量：" + 商品数量);
        System.out.println("商品总价：" + 商品总价 + "元");

        // 添加商品到购物车
        String 购物车 = 商品名称 + "*" + 商品数量 + ",";

        // 输出购物车信息
        System.out.println("购物车：" + 购物车);

        // 继续添加其他商品到购物车
        String 商品2名称 = "耳机";
        double 商品2价格 = 199.99;
        int 商品2数量 = 2;
        double 商品2总价 = 商品2价格 * 商品2数量;

        购物车 += 商品2名称 + "*" + 商品2数量 + ",";

        // 输出购物车信息
        System.out.println("购物车：" + 购物车);
    }
}

In this case, by using Chinese variable names, we can clearly display product information, such as product name, price and quantity. The construction of the shopping cart uses string splicing operations to connect the information of different products in the form of commas. In this way, by reading the code, we can understand the shopping cart construction process more intuitively.

Summary:

The application cases of Chinese variable names in Java programming provide us with more intuitive and easy-to-understand code. Whether it is a student performance management system or a shopping cart function, by using Chinese variable names, we can better understand the meaning and function of the code. However, it should be noted that when using Chinese variable names, programming standards and coding styles must be followed to ensure the readability and maintainability of the code. Chinese variable names need to be used with caution, especially in team collaboration development, and consensus should be reached with team members to avoid unnecessary confusion and misunderstandings.
