Question

我想问一下我的java代码，如何将int值从方法返回到main（），以便从main（）显示为print，这里是我写的代码，但无法从main（）打印：

    package salaryemp;

import java.util.Scanner;

public class SalaryEmp {
int hour_rate, normal, overt, t_normal, t_overt, all_t, otpr;


SalaryEmp(int x,int z, int r){
hour_rate =  x;
normal = z;
overt = r;
}

void Weekcount(){
otpr = (hour_rate/2)+hour_rate;
t_normal = normal*hour_rate;
t_overt = overt*otpr;
all_t = (t_normal + t_overt);  

//Dont want print from this method, i want print from main()
//System.out.println("Your salary for this week is RM: " + t_normal );
//System.out.println("Your salary for this week is RM: " + t_overt );
//System.out.println("Your salary for this week is RM: " + all_t );   

}


public static void main(String[] args) {

       Scanner input = new Scanner(System.in);
       int hourrate, tworkingh, tovertt;
       System.out.print("Insert hourly rate RM: ");
       hourrate = input.nextInt();
       System.out.print("Insert Total working hour : ");
       tworkingh = input.nextInt();
       System.out.print("Insert Total overtime hour : ");
       tovertt = input.nextInt();
       SalaryEmp s1 = new SalaryEmp(hourrate, tworkingh, tovertt);

       s1.Weekcount();

       //*Print result here

   }
}

我希望java中的新手，可以帮我提供一些示例或建议

只需将Weekcount()返回类型设为int

即可

int Weekcount()
{
  otpr = (hour_rate/2)+hour_rate;
  t_normal = normal*hour_rate;
  t_overt = overt*otpr;
  return (t_normal + t_overt); 
 }

并从main()这样调用它。

   int weekCount = s1.Weekcount();
   System.out.println(weekCount);
