看下吧,有什么不足的请指出来
代码一
public double earnings()
{double a=50000.456;
return a;
}
代码二
public double earnings()
{double b=2000;
return 12*b;}
代码三
public double earnings()
{double c=500;
return 52*c;}
代码四
我也正在思考中

JAVA计算工人工资，参考例子如下：
import java.util.Scanner;
public class Demo00 {
//定义一个三维数组，用于记录每个部门、分支、绩效工资
private static final float[][][] SALARY_OF_PER_HOUR = {
{{10.75f,12.50f,14.50f},{11.75f,14.50f,17.50f}},
{{13.00f,16.00f,18.50f},{15.00f,18.50f,22.00f}},
{{16.75f,18.50f,20.50f},{19.25f,25.00f,30.00f}}
};
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
//输入姓名
System.out.println("请输入姓名：");
String name = sc.nextLine();
//输入部门并验证
System.out.println("请输入部门: A,B,C");
char dept = sc.nextLine().charAt(0);
if(dept'A'||dept'C')
{
System.out.println("输入有误，系统将退出");
System.exit(0);
}
//输入分支机构并验证
System.out.println("请输入分支机构: 1,2");
char div = sc.nextLine().charAt(0);
if(div'1'||div'2')
{
System.out.println("输入有误，系统将退出");
System.exit(0);
}
//输入薪绩表并验证
System.out.println("请输入薪绩表: a,b,c");
char sal = sc.nextLine().charAt(0);
if(sal'a'||sal'c')
{
System.out.println("输入有误，系统将退出");
System.exit(0);
}
//输入小时数
System.out.println("请输入本周工作时间（整小时数）：");
int hours = sc.nextInt();
float salary = 0;
//每个小时的薪水
float salaryPerHour = SALARY_OF_PER_HOUR[dept-'A'][div-'1'][sal-'a'];
//分别计算40小时内和超过40小时的薪水
if(hours=40)
{
salary += salaryPerHour*hours;
}
else
{
salary += salaryPerHour*hours+(hours-40)*1.5*salaryPerHour;
}
//输出结果
System.out.println("姓名:\t"+name+"\n部门:\t"+dept+"\n分支机构:\t"+div
+"\n薪绩表:\t"+sal+"\n工作时间:\t"+hours+"\n薪水:\t"+salary);
}
}

用抽象类写最基本的工资计算方法，然后每个不同计算的员工继承这个，使用多态性实例话，大概是这样吧！
