JavaBean 规范设计学生类 Student：计算平均分并输出学生信息

{ "title": "JavaBean 规范设计学生类 Student：计算平均分并输出学生信息", "description": "本示例使用 JavaBean 规范设计了一个学生类 Student，包含学号、姓名、成绩属性，并提供输出学生信息和计算学生平均分的功能。文章通过代码示例，展示了如何创建 Student 对象、存储学生数据、计算平均分以及打印学生信息。", "keywords": "JavaBean, 学生类, Student, 平均分, 代码示例, Java", "content": "1) 学生类 Student 的代码如下：\n\njava\npublic class Student {\n private String no;\n private String name;\n private double score;\n\n public Student(String no, String name, double score) {\n this.no = no;\n this.name = name;\n this.score = score;\n }\n\n public String getNo() {\n return no;\n }\n\n public void setNo(String no) {\n this.no = no;\n }\n\n public String getName() {\n return name;\n }\n\n public void setName(String name) {\n this.name = name;\n }\n\n public double getScore() {\n return score;\n }\n\n public void setScore(double score) {\n this.score = score;\n }\n\n public String toString() {\n return \"学号：\" + no + \"，姓名：\" + name + \"，成绩：\" + score;\n }\n\n public static double getAvg(Student[] students) {\n double sum = 0;\n for (Student student : students) {\n sum += student.getScore();\n }\n return sum / students.length;\n }\n}\n\n\n2) 在 main() 方法中创建五个学生信息，并计算平均分打印所有学生信息的代码如下：\n\njava\npublic class Main {\n public static void main(String[] args) {\n Student[] students = new Student[5];\n students[0] = new Student(\"001\", \"Alice\", 90);\n students[1] = new Student(\"002\", \"Bob\", 85);\n students[2] = new Student(\"003\", \"Charlie\", 95);\n students[3] = new Student(\"004\", \"David\", 80);\n students[4] = new Student(\"005\", \"Eve\", 92);\n\n double avg = Student.getAvg(students);\n\n System.out.println(\"学生信息：\");\n for (Student student : students) {\n System.out.println(student);\n }\n\n System.out.println(\"平均分：\" + avg);\n }\n}\n\n\n运行结果：\n\n\n学生信息：\n学号：001，姓名：Alice，成绩：90.0\n学号：002，姓名：Bob，成绩：85.0\n学号：003，姓名：Charlie，成绩：95.0\n学号：004，姓名：David，成绩：80.0\n学号：005，姓名：Eve，成绩：92.0\n平均分：88.4\n
