Java method to get the time year month and day

This article illustrates how Java gets the year, month, and day. Share with you for your reference. The specific implementation method is as follows:

package com.date.demo; 
import java.text.ParseException; 
import java.text.SimpleDateFormat; 
import java.util.Calendar; 
import java.util.Date; 
public class DateDemo { 
  public static void main(String args[]) { 
    System.out.println("--------------- Gets the date of the current time -----------------"); 
    getMonthDay(); 
    System.out.println("--------------- Gets the year, month and day of the custom time -----------------"); 
    getMonthDay2Set(); 
  } 
   
  private static void getMonthDay2Set() { 
    String dateStr = "2013-11-10 18:45:39"; 
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
    Calendar cal = Calendar.getInstance(); 
    Date dt = null; 
    try { 
      dt = sdf.parse(dateStr); 
      cal.setTime(dt); 
    } catch (ParseException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
    } 
    int year = cal.get(Calendar.YEAR); 
    int month = cal.get(Calendar.MONTH) + 1; 
    int day = cal.get(Calendar.DAY_OF_MONTH); 
    int hour = cal.get(Calendar.HOUR_OF_DAY); 
    int minute = cal.get(Calendar.MINUTE); 
    int second = cal.get(Calendar.SECOND); 
    System.out.println("=== years ===" + year); 
    System.out.println("=== month ===" + month); 
    System.out.println("=== day ===" + day); 
    System.out.println("=== when ===" + hour); 
    System.out.println("=== points ===" + minute); 
    System.out.println("=== seconds ===" + second); 
  } 
   
  private static void getMonthDay() { 
    Calendar cal = Calendar.getInstance(); 
    int year = cal.get(Calendar.YEAR); 
    int month = cal.get(Calendar.MONTH) + 1; 
    int day = cal.get(Calendar.DAY_OF_MONTH); 
    int hour = cal.get(Calendar.HOUR_OF_DAY); 
    int minute = cal.get(Calendar.MINUTE); 
    int second = cal.get(Calendar.SECOND); 
    System.out.println("=== years ===" + year); 
    System.out.println("=== month ===" + month); 
    System.out.println("=== day ===" + day); 
    System.out.println("=== when ===" + hour); 
    System.out.println("=== points ===" + minute); 
    System.out.println("=== seconds ===" + second); 
  } 
}
