사용자 입력을 다른 클래스의 생성자에 전달하는 방법은 무엇입니까?

Question

교수님은 "numberOfDaysInPeriod"및 "SharePointsOnFirstDay"필드가있는 클래스 "SharePattern"을 디자인해야한다고 말했습니다.

클래스에는이 두 필드의 값을 설정하는 생성자가 있어야합니다.

다른 클래스에서 그는 다른 클래스의 메인에서 사용자 입력을 얻으려고 말했다. 그러면 생성자는 무엇이 될까요?

public static void main(String[] args) { 
    // TODO Auto-generated method stub 
    Scanner more = new Scanner(System.in); 
    System.out.print("Number of days in the period: "); 
    int input1 = more.nextInt(); 
    while(input1 < 10 || input1 > 20) 
    { 
     System.out.println("The number of days that is entered must not be less than 10 and more than 20. The number of days doesn't meet the required criteria, enter it again"); 
     System.out.print("Number of days in the period: "); 
     input1 = more.nextInt(); 
    } 

    System.out.print("Share points on the first day: "); 
    int input2 = more.nextInt(); 
    int half = input1/2; 
    more.close(); 


    SharePattern sp = new SharePattern(input1, input2, half); 
    sp.findFinalDaySharePoints(input1, input2, half); 
} 
}
