鹿寨網(wǎng)站制作公司哪家好，找創(chuàng)新互聯(lián)！從網(wǎng)頁(yè)設(shè)計(jì)、網(wǎng)站建設(shè)、微信開發(fā)、APP開發(fā)、成都響應(yīng)式網(wǎng)站建設(shè)等網(wǎng)站項(xiàng)目制作，到程序開發(fā)，運(yùn)營(yíng)維護(hù)。創(chuàng)新互聯(lián)從2013年開始到現(xiàn)在10年的時(shí)間，我們擁有了豐富的建站經(jīng)驗(yàn)和運(yùn)維經(jīng)驗(yàn)，來保證我們的工作的順利進(jìn)行。專注于網(wǎng)站建設(shè)就選創(chuàng)新互聯(lián)。
import java.util.Calendar;
public class TestDate {
public static final String[] weeks = { "日", "一", "二", "三", "四", "五", "六" };
public static void main(String[] args) {
Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR,2011);//2011年
c.set(Calendar.MONTH,0);//java中Calendar類，月從0開始， 0代表一月
c.set(Calendar.DATE,1);//1號(hào)
int day = c.get(Calendar.DAY_OF_WEEK);//獲致是本周的第幾天地, 1代表星期天...7代表星期六
System.out.println(new SimpleDateFormat( "yyyy-MM-dd ").format(c.getTime()));
System.out.println("星期" + weeks[day-1]);
}
}
把以上測(cè)試代碼寫作一個(gè)方法 方法的參數(shù)名為年月日， 即可。當(dāng)然Calendar 還有很多功能，比如一周的第幾天，一年的第幾個(gè)月……
用JAVA編寫一個(gè)萬年歷
import java.io.*;

for(i=x;ix+y;i++)
a[i]=i-x+1;
for(i=x;ix+y;i++)
{
if ((i%7==0)(i0))
System.out.print("\n");
if (a[i]10)
System.out.print(" "+a[i]);
else System.out.print(" "+a[i]);
}
System.out.println("\n");
}

編寫 萬年歷java代碼例如1900年一月一日是星期一。

System.out.println("輸入年月(年和月用非數(shù)字隔開:如2015.1)(什么都不輸入直接退出)");
String?line?=?scanner.nextLine().trim();
if("".equals(line))

if(!line.matches(reg))
