如何用JAVA写日历?

按照你的要求编写的Java日历验证程序如下

UI.java

import?java.util.Scanner;

public?class?UI?{

static?Scanner?sc=new?Scanner(System.in);

public?static?int?askInt(String?s){

System.out.print(s);

return?sc.nextInt();

public?static?void?println(String?s){

System.out.println(s);

EE.java

public?class?EE?{

public?void?validateDateCore(){

int?year?=UI.askInt("Enter?the?year:?");

int?month=UI.askInt("Enter?the?month:?");

int?day=UI.askInt("Enter?the?day:?");

if(year?1){

UI.println("The?year?is?not?a?valid?number.");

UI.println("The?month?is?not?a?valid?number.");

int?monthDay=0;

switch(month){

case?1:

case?10:

}else{

if(day1?||?daymonthDay){

UI.println("The?day?is?not?a?valid?number.");

UI.println("It?is?"+day+"/"+month+"/"+year+".");

new?EE().validateDateCore();

运行结果
