Get time units hours and minutes from Date in String format -

This tutorial shows how to get time units hours and minutes from Date in String format using java.text.SimpleDateFormat class. SimpleDateFormat class allows us to format date to text and to parse text to date.

Example: Time units hours and minutes from Date

package com.sneppets.example;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.time.LocalDate;
import java.time.ZoneId;
import java.util.Date;

public class HoursMinutesFromDateExample {
	
	public static void main (String[] args) {
		
		String startDateTime = "2020-02-10T10:15:00";
		SimpleDateFormat sdfdatetime = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
		SimpleDateFormat sdfHH = new SimpleDateFormat("HH");		
		SimpleDateFormat sdfmm = new SimpleDateFormat("mm");	
		
		Date date;
		try {
			date = sdfdatetime.parse(startDateTime);
			LocalDate startDateLocal = date.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
			System.out.println("Start Date : "+ startDateLocal);
			
			int startHour = Integer.parseInt(sdfHH.format(date));
			System.out.println("Start Hour : " + startHour);
			
			int startMinute = Integer.parseInt(sdfmm.format(date));
			System.out.println("Start Minute : " + startMinute);
			
		} catch (ParseException e) {

			e.printStackTrace();
		}	
	}

}

Output

Start Date : 2020-10-02
Start Hour : 10
