How can I use an object outside of it's declared scope?

Question

For example, if I have a class Student and an student object inside of it with the value of 5, also some getters and setters

public class Student {
    int age;

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
    public static void run() {
        Student stud = new Student();
        stud.setAge(5);
    }
}

And I have another class called getStudent

public class GetStudent {
    int studAge = stud.getAge;
}

Now this, obviously, gives me an error. Is there any way to access the stud object and it's methods outside of it's class?

如果您总是只想通过public static void run()方法访问 Student 对象，请查看单例设计模式。
