下面使用对象调用get（）方法来获取年月日字段
public int get?(int field)
complete()方法处理，该过程是与日历系统相关的。field - 给定的日历字段。ArrayIndexOutOfBoundsException - 如果指定的字段超出范围（ field < 0 || field >= FIELD_COUNT ）。set(int,int) ， complete()package com.Test01;
import java.util.Calendar;
public class CalendarDemo {
public static void main(String[] args) {
//获取对象
Calendar c = Calendar.getInstance();
System.out.println(c);
// public int get?(int field)
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH)+1;
int date = c.get(Calendar.DATE);
System.out.println(year+"年"+month+"月"+date+"日");
}
}
package com.Test01;

public static void main(String[] args) {
//获取对象
Calendar c = Calendar.getInstance();
System.out.println(c);
// public int get?(int field)
c.add(Calendar.YEAR,2);
c.add(Calendar.MONTH,-1);
c.set(2050,11,25);
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH)+1;
int date = c.get(Calendar.DATE);
System.out.println(year+"年"+month+"月"+date+"日");
}
}
字段格式：Calendar.YEAR or MONTH or DATE;
