舉例：

public class Employee {

private String name;

private double salary = 15000.00;

private Date birthDate;

public Employee(String n, Date Dob) {

name = n;

birthDate = Dob;

}

public Employee(String n) {

this (n,null);

}

}

public class Manager extends Employee {

private String department;

public Manager(String n, String d) {

super(n);

department = d;

}

}

結論：

子類可以繼承父類所有的屬性和方法（包括Private私有屬性和方法），不過子類不可以直接訪問到父類的Private屬性和方法。
