Question

日曆從星期一開始，並返回1到int星期幾，我的代碼應該這樣做。我想不通當你把一個分號你if語句的結束下一步該怎麼做下一個，因爲所有我試過了，我得到了錯誤

import java.applet.Applet; 
import java.util.*; 
import java.awt.*; 

public class Dates2Applet extends Applet 
{ 
    public static void main(String[] args) 
    { 
    Calendar c = Calendar.getInstance(); 
    int wDay = c.get (Calendar.DAY_OF_WEEK); 

    if(Calendar.MONDAY == c.getFirstDayOfWeek()); 
    { 
     System.out.println("Monday is the first day of the week"); 
    } 

    if(Calendar.MONDAY == c.get(Calendar.DAY_OF_WEEK)); 
    { 
     System.out.println("Monday close books"); 
    } 

    if(Calendar.DAY_OF_WEEK == c.get(Calendar.DAY_OF_WEEK)); 
    { 
     System.out.println("Normal week day"); 
    } 

    if(Calendar.SATURDAY ==0 || Calendar.SUNDAY ==0); 
    { 
     System.out.println("Match Day"); 
    } 
}

它創建一個行身上，然後你的括號不依賴於if（這也是爲什麼，大概是else沒有爲你工作。） - 我想你想要的東西一樣，

if(Calendar.MONDAY == c.getFirstDayOfWeek()) { 
    System.out.println("Monday is the first day of the week"); 
} 
if(Calendar.MONDAY == c.get(Calendar.DAY_OF_WEEK)) { 
    System.out.println("Monday close books"); 
} else if(Calendar.DAY_OF_WEEK == c.get(Calendar.DAY_OF_WEEK)) { 
    System.out.println("Normal week day"); 
} else if(Calendar.SATURDAY ==0 || Calendar.SUNDAY ==0) { 
    System.out.println("Match Day"); 
}
