java中Calendar类提供了月份计算方法的,直接通过Month方法进行计算得出月份差,之后算出年份的差乘以12,之后的和就是月份差。
public void monthSpace() throws ParseException {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String str1 = "2012-02-01";
String str2 = "2012-02-2";
Calendar bef = Calendar.getInstance();
Calendar aft = Calendar.getInstance();
bef.setTime(sdf.parse(str1));
aft.setTime(sdf.parse(str2));
int result = aft.get(Calendar.MONTH) - bef.get(Calendar.MONTH);
int month = (aft.get(Calendar.YEAR) - bef.get(Calendar.YEAR))*12;
System.out.println(month+result );
}
