Java中判断两个日期是否在同一个月

    
	public boolean isMonth(Date date1, Date date2) {
		Calendar calendar1 = Calendar.getInstance();
		calendar1.setTime(date1);
		Calendar calendar2 = Calendar.getInstance();
		calendar2.setTime(date2);
		int year1 = calendar1.get(Calendar.YEAR);
		int year2 = calendar2.get(Calendar.YEAR);
		int month1 = calendar1.get(Calendar.MONTH);
		int month2 = calendar2.get(Calendar.MONTH);
		System.out.println(year1 + "  " + month1);
		System.out.println(year2 + "  " + month2);
		return calendar1.get(Calendar.YEAR) == calendar2.get(Calendar.YEAR) && calendar1.get(Calendar.MONTH) == calendar2.get(Calendar.MONTH);

	}
