public class TestEmployee {//测试类
public static void main(String[] args) {

输出

class YG implements ComparableYG{//员工类,实现比较接口
String name;//姓名
int gz;//工资
public YG(String name, int gz) {

}

一：将员工姓名、工资封装成一个对象
public class Staff {
private String name;
private int salary;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getSalary() {
return salary;
}
public void setSalary(int salary) {
this.salary = salary;
}
public Staff(String name, int salary) {
super();
this.name = name;
this.salary = salary;
}
}
二：初始化一个数组，算平均工资
public class Average {
public static void main(String[] args) {
Staff staffs[] = {new Staff("zhangsan", 1000), new Staff("lisi", 1100), new Staff("wangwu", 1200)};
int sum = 0;
for(Staff staff : staffs) {
sum = sum + staff.getSalary();
}
System.out.println("员工人数：" + staffs.length + " 总工资：" + sum + " 平均工资：" + sum / staffs.length);
}
}
abstract class Person{
private String name;

}
public abstract double counting();

}
public double getBasicWage(){

}

this.allowance = allowance;
}
public double getAllowance(){

}
public double counting(){

}
}

manage.setBasicWage(1000d);

System.out.println(manage.getName()+"工资为:"+manage.counting());

Teacher teacher1 = new Teacher("赵六","讲师");
teacher1.setHours(60);
System.out.println(teacher1.getName()+"工资为:"+teacher1.counting
());
}
}
看下吧,有什么不足的请指出来
