public class Student {
    private String name;
    private int age;
    private double javaScore;

    public Student(String name, int age, double javaScore) {
        this.name = name;
        this.age = age;
        this.javaScore = javaScore;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public double getJavaScore() {
        return javaScore;
    }
}

public class Main {
    public static void main(String[] args) {
        Student s1 = new Student("张三", 20, 90);
        Student s2 = new Student("李四", 21, 80);
        Student s3 = new Student("王五", 22, 85);
        Student s4 = new Student("赵六", 23, 95);
        Student s5 = new Student("钱七", 24, 75);

        System.out.println(s1.getName() + " " + s1.getAge() + " " + s1.getJavaScore());
        System.out.println(s2.getName() + " " + s2.getAge() + " " + s2.getJavaScore());
        System.out.println(s3.getName() + " " + s3.getAge() + " " + s3.getJavaScore());
        System.out.println(s4.getName() + " " + s4.getAge() + " " + s4.getJavaScore());
        System.out.println(s5.getName() + " " + s5.getAge() + " " + s5.getJavaScore());

        double total = s1.getJavaScore() + s2.getJavaScore() + s3.getJavaScore() + s4.getJavaScore() + s5.getJavaScore();
        double average = total / 5;
        System.out.println("平均成绩：" + average);

        double max = s1.getJavaScore();
        double min = s1.getJavaScore();
        if (s2.getJavaScore() > max) {
            max = s2.getJavaScore();
        }
        if (s3.getJavaScore() > max) {
            max = s3.getJavaScore();
        }
        if (s4.getJavaScore() > max) {
            max = s4.getJavaScore();
        }
        if (s5.getJavaScore() > max) {
            max = s5.getJavaScore();
        }

        if (s2.getJavaScore() < min) {
            min = s2.getJavaScore();
        }
        if (s3.getJavaScore() < min) {
            min = s3.getJavaScore();
        }
        if (s4.getJavaScore() < min) {
            min = s4.getJavaScore();
        }
        if (s5.getJavaScore() < min) {
            min = s5.getJavaScore();
        }

        System.out.println("最高成绩：" + max);
        System.out.println("最低成绩：" + min);
    }
}

### 回答2：
根据类Student的定义，我们可以创建五个该类的对象来表示五个学生的信息。为了计算Java语言成绩的平均值、最大值和最小值，我们需要在类Student中定义成绩相关的属性和方法。

首先，我们可以定义类Student如下：

class Student {
  String name;  // 学生姓名
  int javaScore;  // Java语言成绩

  // 构造方法
  public Student(String name, int javaScore) {
    this.name = name;
    this.javaScore = javaScore;
  }

  // 返回学生姓名
  public String getName() {
    return this.name;
  }
  
  // 返回Java语言成绩
  public int getJavaScore() {
    return this.javaScore;
  }
}

然后，我们可以创建五个该类的对象，并输出每个学生的信息：

public static void main(String[] args) {
  // 创建五个Student对象
  Student student1 = new Student("小明", 80);
  Student student2 = new Student("小红", 90);
  Student student3 = new Student("小刚", 75);
  Student student4 = new Student("小李", 85);
  Student student5 = new Student("小张", 95);

  // 输出每个学生的信息
  System.out.println("学生1：" + student1.getName() + "，Java成绩：" + student1.getJavaScore());
  System.out.println("学生2：" + student2.getName() + "，Java成绩：" + student2.getJavaScore());
  System.out.println("学生3：" + student3.getName() + "，Java成绩：" + student3.getJavaScore());
  System.out.println("学生4：" + student4.getName() + "，Java成绩：" + student4.getJavaScore());
  System.out.println("学生5：" + student5.getName() + "，Java成绩：" + student5.getJavaScore());
}

接下来，我们需要计算这五个学生Java语言成绩的平均值、最大值和最小值。我们可以在main方法中添加以下代码来实现：

// 计算平均值、最大值和最小值
int totalScore = student1.getJavaScore() + student2.getJavaScore() + student3.getJavaScore()
                + student4.getJavaScore() + student5.getJavaScore();
double averageScore = totalScore / 5.0;
int maxScore = Math.max(Math.max(student1.getJavaScore(), student2.getJavaScore()),
                        Math.max(student3.getJavaScore(), student4.getJavaScore()));
maxScore = Math.max(maxScore, student5.getJavaScore());
int minScore = Math.min(Math.min(student1.getJavaScore(), student2.getJavaScore()),
                        Math.min(student3.getJavaScore(), student4.getJavaScore()));
minScore = Math.min(minScore, student5.getJavaScore());

// 输出平均值、最大值和最小值
System.out.println("平均值：" + averageScore);
System.out.println("最大值：" + maxScore);
System.out.println("最小值：" + minScore);

最后，运行程序就可以输出每个学生的信息以及Java语言成绩的平均值、最大值和最小值。

根据类 Student 的定义，创建五个该类的对象，可以这样做：

# 定义 Student 类
class Student:
    def __init__(self, name, java_score):
        self.name = name
        self.java_score = java_score

# 创建五个 Student 对象
student1 = Student("张三", 80)
student2 = Student("李四", 90)
student3 = Student("王五", 85)
student4 = Student("赵六", 95)
student5 = Student("钱七", 88)

# 输出每个学生的信息
print("学生1：", student1.name, " Java 语言成绩：", student1.java_score)
print("学生2：", student2.name, " Java 语言成绩：", student2.java_score)
print("学生3：", student3.name, " Java 语言成绩：", student3.java_score)
print("学生4：", student4.name, " Java 语言成绩：", student4.java_score)
print("学生5：", student5.name, " Java 语言成绩：", student5.java_score)

# 计算并输出五个学生 Java 语言成绩的平均值
average_score = (student1.java_score + student2.java_score + student3.java_score + student4.java_score + student5.java_score) / 5
print("平均成绩：", average_score)

# 计算并输出五个学生 Java 语言成绩的最大值和最小值
max_score = max(student1.java_score, student2.java_score, student3.java_score, student4.java_score, student5.java_score)
min_score = min(student1.java_score, student2.java_score, student3.java_score, student4.java_score, student5.java_score)
print("最大成绩：", max_score)
print("最小成绩：", min_score)

以上代码根据类 Student 的定义创建了五个学生对象，并输出了每个学生的信息。然后计算并输出了这五个学生 Java 语言成绩的平均值、最大值和最小值。
