实现思路：

　　通过Calendar类的before来判断两个日期是否符合前一个日期小于后一个日期。

　　实现：

1         Calendar c1 = Calendar.getInstance(); 2         Calendar c2 = Calendar.getInstance(); 3         c1.set(2014, 9, 30); 4         c2.setTime(new Date()); 5         System.out.println(c1.get(Calendar.YEAR)+" "+c1.get(Calendar.MONTH)); 6         while (c1.before(c2)) { 7             int m = c1.get(Calendar.MONTH)+1; 8             System.out.println(c1.get(Calendar.YEAR)+" "+(c1.get(Calendar.MONTH)+1)); 9             c1.add(Calendar.MONTH,1);10         }11         System.out.println(c1.get(Calendar.YEAR)+" "+(c1.get(Calendar.MONTH)+1));
