本文提供了一个简单的Java程序，用于计算两个日期之间的天数差，并将其转换为年、月、日的形式展示。该程序通过字符串操作和基本的数学计算实现日期间的距离计算。

public

class CalcDate { /** * @param args * @author wuyaowen * function calculate distance of two date given * such as 2009.03.05 ~ 2005.09.07 */ public int calcDate(String dateBegin, String dateEnd){ int distance = 0; // 时间之间的天数

String db = dateBegin; // 开始日期

String de = dateEnd; // 结束日期

int strby = 0; // substring of begin date year 开始日期的年份
int strbm = 0; // 开始日期的月份
int strbd = 0; // 开始日期的日子
int strey = 0; int strem = 0; int stred = 0;

// 类型转换

strby = Integer.parseInt(db.substring(0, 4));

strbm = Integer.parseInt(db.substring(5, 7));

strbd = Integer.parseInt(db.substring(8, 10));

strey = Integer.parseInt(de.substring(0, 4));

strem = Integer.parseInt(de.substring(5, 7));

stred = Integer.parseInt(de.substring(8, 10));

if(stred < strbd){

stred = stred + 30;

strem = strem -1;

}

if(strem < strbm){

strem = strem + 12;

strey = strey -1;

}

distance = (strey - strby)*365 + (strem - strbm)*30 + stred - strbd;

return distance;

}

public static void main(String[] args) { // TODO Auto-generated method stub

CalcDate cd =

new CalcDate(); int dates = cd.calcDate("2005-09-07", "2009-03-05");

System.

out.print(dates/365 + " years " + dates%365/30 + " months " + dates%365%30 + " dates");

/**

debugging int test = 1287%365/30; System.out.print("/n" + test); //test subString() String str = "C12natown"; String subStr = str.substring(1, 3); System.out.println(Integer.parseInt(subStr)-1);

}

// End of main()

}
