java编写一个学生类测试类

以下是一个简单的Java学生类和测试类的示例：

学生类：

public class Student {
    private String name;
    private int age;
    private String major;

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

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public String getMajor() {
        return major;
    }
}

测试类：

public class TestStudent {
    public static void main(String[] args) {
        Student student1 = new Student("Alice", 20, "Computer Science");
        Student student2 = new Student("Bob", 21, "Business");

        System.out.println(student1.getName() + " is " + student1.getAge() + " years old and majors in " + student1.getMajor());
        System.out.println(student2.getName() + " is " + student2.getAge() + " years old and majors in " + student2.getMajor());
    }
}

输出结果：

Alice is 20 years old and majors in Computer Science
Bob is 21 years old and majors in Business
