    this.num = num;
}

public String getName() {
    return name;
}

}

public float getAward() {
    return award;
}

public void setAward(float award) {

}

public float getSalary(float basic_salary, float award){
    return basic_salary+award;
}
@Override
public String toString() {
    return "Employee [num=" + num + ", name=" + name + ", position=" + position + ", date=" + date
            + ", salary=" + getSalary(basic_salary , award) + "]";
}

}
//测试
package com.njupt.www;

public class Test {

public static void main(String[] args) {
    Employee employee = new Employee(1001,"李雷","经理","2016-04-15",8000,2000);
    System.out.println(employee.toString());


}
