[Tecnología Java Core (Volumen I)]: vscode compila y ejecuta manualmente clases heredadas

• Referencia-P160 ~ P161

• Hay tres clases principales: una clase de prueba (ManagerTest), una subclase (Manager) y una clase principal (Empleado)

• Precauciones:
  -1 usando javac -d . *.javaprecompilado
  

  La estructura del directorio
  
  es la siguiente: En este momento, la estructura del directorio se generará de la siguiente manera:
  

• Correr tras java com.inheritance.ManagerTest
  

• Adjunta el código de varias clases

// com.inheritance.Manager.java
package com.inheritance;

public class Manager extends Employee{
    
    
  private double bonus;

  public Manager(String name, double salary, int year, int month, int day) {
    
    
    super(name, salary, year, month, day);
    bonus = 0;
  }

  public double getSalary() {
    
    
    double baseSalary = super.getSalary();
    return baseSalary + bonus;
  }

  public void setBonus(double b) {
    
    
    bonus = b;
  }
}

// com.inheritance.Employee.java
package com.inheritance;

import java.time.*;

public class Employee {
    
    
  private String name;

  public void raiseSalary(double byPercent) {
    
    
    double raise = salary * byPercent / 100;
    salary += raise;
