以下是一个实现要求的Java代码： ```java public class Student { private String studentId; private String name; private double mathScore; private double englishScore; private double computerScore; public Student(String studentId, String name, double mathScore, double englishScore, double computerScore) { this.studentId = studentId; this.name = name; this.mathScore = mathScore; this.englishScore = englishScore; this.computerScore = computerScore; } public double getTotalScore() { return mathScore + englishScore + computerScore; } public double getAverageScore() { return getTotalScore() / 3; } public double getMaxScore() { return Math.max(mathScore, Math.max(englishScore, computerScore)); } public double getMinScore() { return Math.min(mathScore, Math.min(englishScore, computerScore)); } // Getters and setters public String getStudentId() { return studentId; } public void setStudentId(String studentId) { this.studentId = studentId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public double getMathScore() { return mathScore; } public void setMathScore(double mathScore) { this.mathScore = mathScore; } public double getEnglishScore() { return englishScore; } public void setEnglishScore(double englishScore) { this.englishScore = englishScore; } public double getComputerScore() { return computerScore; } public void setComputerScore(double computerScore) { this.computerScore = computerScore; } } ``` 下面是一个简单的测试示例： ```java public class StudentTest { public static void main(String[] args) { Student student1 = new Student("1001", "Alice", 85, 90, 78); System.out.println("Total Score: " + student1.getTotalScore()); System.out.println("Average Score: " + student1.getAverageScore()); System.out.println("Max Score: " + student1.getMaxScore()); System.out.println("Min Score: " + student1.getMinScore()); } } ``` 这个示例中，我们首先创建了一个名为"student1"的Student对象，并传入学号、姓名以及三门课程的成绩。然后我们通过调用相应的方法，计算总分、平均分、最高分和最低分，并打印输出这些结果。 [2024-03-12 10:23:27 | AI写代码神器 | 2332点数解答]
