用最笨的方法实现java控制台日历打印

如果想用户自定义输入日期查询，可以通过Calendar的set方法和Scanner方法设置

Calendar类简单使用：https://blog.csdn.net/weixin_43670802/article/details/89953759

package test1.three;import java.text.SimpleDateFormat;
import java.util.Calendar;public class MyCalendar {
public static void printCalendar(){//本月时长，打印变量,当前日期
int days=0,n=1,div=0;SimpleDateFormat format=new SimpleDateFormat("yyyy年MM月");
Calendar now=Calendar.getInstance();
//-------------------------------------------------
//得到当前日期
div=now.get(Calendar.DAY_OF_MONTH);
//-------------------------------------------------
//得到本月天数
now.add(Calendar.MONTH,1);
now.set(Calendar.DAY_OF_MONTH,1);
now.add(Calendar.DAY_OF_MONTH,-1);
days=now.get(Calendar.DAY_OF_MONTH);
//-------------------------------------------------
//当前月份日历显示
System.out.println("傻瓜式日历："+format.format(now.getTime()));
System.out.println("--------------------------------------------------");
//-------------------------------------------------
//设置为月初
now.set(Calendar.DAY_OF_MONTH,1);
//-------------------------------------------------
//表头
String[] week={"日","一","二","三","四","五","六"};
//-------------------------------------------------
//打印表头
for(int i=0;i<week.length;i++){System.out.print(""+week[i]);
}
//换行
System.out.print("\n");
//-------------------------------------------------
//打印第一行
for(int i=1;i<now.get(Calendar.DAY_OF_WEEK);i++){
System.out.print("");
}
for(int j=0;j<=7-now.get(Calendar.DAY_OF_WEEK);j++){
//判断是否超出本月期限
if(n<=days){
//判断是否是当前日
if(n==div)
System.out.print("["+(n++)+"]");
else
System.out.print(n++);
}
System.out.print("");
}
System.out.print("\n");//-------------------------------------------------
//打印其余部分
for(int i=0;i<days/7+1;i++){
//7列
for(int j=0;j<7;j++){
//判断是否超出本月期限
if(n<=days){
//判断是否是当前日
if(n==div)
System.out.print("["+(n++)+"]");
else
System.out.print(n++);
}//间距
System.out.print("");
}
//换行
System.out.print("\n");
}
//-------------------------------------------------}}
