-java繼承思想的實(shí)現(xiàn)

package java_object.week2;

員工類

public class Employee {
private String name;
private int age;
private double salary = 2000;

public Employee(String name, int age, double salary) {
    this.name = name;
    this.age = age;
    this.salary = salary;
}
public Employee(){}
public double getSalary(){
    return salary;
}

}

經(jīng)理類

public class Msnsger extends Employee {
private double bonus;
public void setBonus(double bonus){
this.bonus = bonus;
}
}

測試類

public class Test {
public static void main(String[] args) {
Msnsger msnsger = new Msnsger();
double sal = msnsger.getSalary();
System.out.println("繼承的薪水為:"+sal);
}
}

-因?yàn)閱T工有的屬性經(jīng)理也有，所以使用繼承可以避免重復(fù)代碼的出現(xiàn)
