While 루프는 내 멀티 클래스 프로그램에서 한 번만 실행됩니다.

Question

모든 백 엔드 "계산"내 while 루프를 수행하는 클래스 중 하나는 한 번만 실행되는 것 같습니다. 내 코드는 모두 작동하는 것처럼 보이고 심지어 출력도 나오지만 while 루프가 한 번만 실행 된 후에야 출력됩니다. 클래스의 모든 입력은 다른 클래스에서 가져온 것이고 출력은 입력을받는 것과 동일한 클래스로 인쇄됩니다. 추가 도움을 주시면 감사하겠습니다.

calculating class code: 

package clock; 

public class basic { 

    static displayFrame outputs = new displayFrame(); 

    public static String output; 

    public static String findDate(int year, int month, int day, int hour, int timeToAdd){ 

     double yearD = year; 
     double leapYear = yearD/4; 
     int daysInMonth = 0; 
     int daysInYear = 365; 
     int casePick = 0; 
     int x = 0; 

    //Making sure that the number added isn't negative, ones for other inputs MAY come... 
    while(x == 0) 
    { 
    if(Math.abs(timeToAdd) != timeToAdd){ 
     continue; 
    }else{

이 어떤 도움이 크게 감사합니다, 감사합니다!

Answer 1

break을 switch 성명 외부로 호출 할 때마다 즉시 while 루프를 종료합니다.

루프의 시작 부분으로 이동하려면 continue을 대신 사용하십시오.
