是不是这样啊 只是感觉有点麻烦 
Calendar calendar=Calendar.getInstance();
for(int i=1;i<14;i++){
calendar.set(Calendar.DAY_OF_MONTH, i);
if(calendar.get(Calendar.DAY_OF_WEEK)==Calendar.MONDAY){
System.out.println(calendar.get(Calendar.YEAR)+"-"+(calendar.get(Calendar.MONTH)+1)+"-"+calendar.get(Calendar.DATE));
break;
}

}

Calendar calendar=Calendar.getInstance();
int days=calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
int n=0;
for(int i=1;i<=days;i++){
calendar.set(Calendar.DAY_OF_MONTH, i);
if(calendar.get(Calendar.DAY_OF_WEEK)==Calendar.MONDAY){
System.out.println(calendar.get(Calendar.YEAR)+"-"+(calendar.get(Calendar.MONTH)+1)+"-"+calendar.get(Calendar.DATE));
n++;
}
}
System.out.println(n);
