Question

日历从星期一开始，并返回1到int星期几，我的代码应该这样做。我想不通当你把一个分号你if语句的结束下一步该怎么做下一个，因为所有我试过了，我得到了错误

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"); 
    } 
}

它创建一个行身上，然后你的括号不依赖于if（这也是为什么，大概是else没有为你工作。） - 我想你想要的东西一样，

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"); 
}
