Calendar类学习，自己写了个日历查询小程序，供大家学习参考

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.Scanner;

public class visualCalendar {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
	    System.out.println("请输入您要查询的日期,格式：2015-05-14");
        Scanner can= new Scanner(System.in);
         String  temp= can.next();
		  try {
				//String转换成Date
			DateFormat  format= new  SimpleDateFormat("yyyy-MM-dd");
			Date date=format.parse( temp);
			//使用日历类
			Calendar  calendar=new GregorianCalendar();
			//把日期设置为Calendar型
		    calendar.setTime(date);
		    
		    calendar.set(Calendar.DATE, 1);
		    
		    calendar.get(Calendar.DAY_OF_WEEK);
          int maxdate =calendar.getActualMaximum(Calendar.DATE);
     
			System.out.println("日\t一\t二\t三\t四\t五\t六");
			for(int i=1;i<calendar.get(Calendar.DAY_OF_WEEK);i++){
				System.out.print("\t");
			}
			
			
			for(int i=1;i<=maxdate;i++){
			
			
				System.out.print(i+"\t");
				int  w=calendar.get(Calendar.DAY_OF_WEEK);
				if(w==Calendar.SATURDAY){
					System.out.print("\n");
				}
				calendar.add(Calendar.DATE, 1);
			}
		} catch (ParseException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
