M：模型

public class Student {
   private String rollNo;
   private String name;
   public String getRollNo() {
      return rollNo;
   }
   public void setRollNo(String rollNo) {

   }
   public String getName() {
      return name;
   }
   public void setName(String name) {
      this.name = name;
   }
}

V:视图

public class StudentView {
   public void printStudentDetails(String studentName, String studentRollNo){
      System.out.println("Student: ");
      System.out.println("Name: " + studentName);
      System.out.println("Roll No: " + studentRollNo);
   }
}

C:控制器

public class StudentController {

   public StudentController(Student model, StudentView view){
      this.model = model;
      this.view = view;
   }
 
   public void setStudentName(String name){

   }
 
   public String getStudentName(){
      return model.getName();    
   }
 
   public void setStudentRollNo(String rollNo){
      model.setRollNo(rollNo);      
   }
 
   public String getStudentRollNo(){
      return model.getRollNo();     
   }
 
   public void updateView(){           
      view.printStudentDetails(model.getName(), model.getRollNo());
   }
