我想首先说我是Java的新手，这也是我第一次在这个网站上提问。在试图弄清楚如何在方法中打破这个小程序3天后，我还没有能够这样做。有人可以帮我吗？
我一直在阅读，看起来我违反了单一责任原则。任何意见都会受到欢迎。
public class RateSystem {
double employeeSalary;
public int salaryRate(String employeePosition) {
if (employeePosition.equalsIgnoreCase("1")) {
return 40;
} else if (employeePosition.equalsIgnoreCase("2")) {
return 30;
} else
employeePosition.equalsIgnoreCase("3");
return 50;
}
}
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Employee position please...");
System.out.println("Press 1 for IT " + "\n" + "Press 2 for Tech" +
"\n" + "Press 3 for engineer");
String ePosition = input.nextLine();
RateSystem raul = new RateSystem();
int getPay = raul.salaryRate(ePosition);
System.out.println("How many hours did he work for the week?...");
int weekHours = input.nextInt();
int totalPay = 0;
if (weekHours <= 40) {
totalPay = getPay * weekHours;
System.out.println("Employee salary is " + totalPay);
} else {
int overTimeHours = weekHours - 40;
int extra$$PerOverTime = overTimeHours * getPay +(overTimeHours * getPay/2);
totalPay = getPay * (weekHours - overTimeHours);
System.out.println("The employee accumulated 40 hours equivalent to $"+
totalPay + " plus $" + extra$$PerOverTime + " overtime hours, a total of $"+(extra$$PerOverTime + totalPay));
}
}
}

如果我们查看main()，它会执行多项任务：
初学者的表现如何
答案 1 :(得分：0)
我看到可以添加以下内容。
1）为员工创建工资，为什么不创建和Employee类，并在其中封装详细信息，如＆＃34; employeePosition＆＃34;。因此，您可以在以后添加更多内容并在其中设置setter，您将有机会更改员工的setter逻辑。
2）您可以创建一个Calculator类并创建接受单个Employee或Employees列表的方法，并计算他们的工资率。
3）您还可以添加打印相关课程。因此，您可以为单个或员工列表生成不同的打印，或者可能类似于表格格式。
答案 2 :(得分：0)
我在您的代码中确定了以下方法。
1）showMainMenu - ＆gt;负责向用户显示菜单
2）readMenuSelection - ＆gt;在这里，您将阅读主菜单中选择的任何用户。应该用int值而不是string来读取它。
3）对于菜单中的每个选择，将有单独的方法，如payForIT（），payForTech（）和payForEngineer（）

要遵循单一责任原则，您必须为程序中的每个常见任务创建方法。这有助于不重复代码并有助于在一个地方修改代码。
我已经创建了单独的方法来构建字符串和打印字符串，因为在代码中经常使用它：
package com.stackoverflow.main;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
println("Employee position please...");
println(buildString("Press 1 for IT ", "\n", "Press 2 for Tech", "\n", "Press 3 for engineer"));
String ePosition = input.nextLine();
RateSystem raul = new RateSystem();
int getPay = raul.salaryRate(ePosition);
println("How many hours did he work for the week?...");
int weekHours = input.nextInt();
int totalPay = 0;
if (weekHours <= 40) {
totalPay = getPay * weekHours;
println(buildString("Employee salary is ", String.valueOf(totalPay)));
} else {
int overTimeHours = weekHours - 40;
int extra$$PerOverTime = overTimeHours * getPay + (overTimeHours * getPay / 2);
totalPay = getPay * (weekHours - overTimeHours);
println(buildString("The employee accumulated 40 hours equivalent to $", String.valueOf(totalPay),
" plus $", String.valueOf(extra$$PerOverTime), " overtime hours, a total of $",
String.valueOf((extra$$PerOverTime + totalPay))));
}
}
private static String buildString(String... strings) {
StringBuilder builder = new StringBuilder();
for (String string : strings) {
builder.append(string);
}
return builder.toString();
}
private static void println(String s) {
System.out.println(s);
}
}
班级RateSystem：
package com.stackoverflow.main;
public class RateSystem {
double employeeSalary;
public int salaryRate(String employeePosition) {
if (equalsIgnoreCase(employeePosition, "1")) {
return 40;
} else if (equalsIgnoreCase(employeePosition, "2")) {
return 30;
} else if (equalsIgnoreCase(employeePosition, "3"))
return 50;
return 0;
}
private boolean equalsIgnoreCase(String arg1, String arg2) {
return arg1.equalsIgnoreCase(arg2);
}
}
