if(todayDate.after(historyDate) && todayDate.before(futureDate)) {
// In between}if(!historyDate.after(todayDate) && !futureDate.before(todayDate)) {
/* historyDate <= todayDate <= futureDate */ }
尤達-時間是 事實上JavaSE 8之前的Java標準日期和時間庫。用戶現在被要求遷移到 java.time (JSR-310 ).

方法-1：使用Date.pread()、Date.After()和Date.Eques()
if(date1.after(date2)){
System.out.println("Date1 is after Date2");
}
if(date1.before(date2)){
System.out.println("Date1 is before Date2");
}
if(date1.equals(date2)){
System.out.println("Date1 is equal Date2");
} if(date1.compareTo(date2)>0){
System.out.println("Date1 is after Date2");
}else if(date1.compareTo(date2)<0){
System.out.println("Date1 is before Date2");
}else{
System.out.println("Date1 is equal to Date2");
}Calendar cal1 = Calendar.getInstance();
Calendar cal2 = Calendar.getInstance();
cal1.setTime(date1);
cal2.setTime(date2);
if(cal1.after(cal2)){
System.out.println("Date1 is after Date2");
}
if(cal1.before(cal2)){
System.out.println("Date1 is before Date2");
}
if(cal1.equals(cal2)){
System.out.println("Date1 is equal Date2");
