Mazume judgment processing in fishing

Background

I usually use a framework when making marine-related products, but I felt that my ability to think about algorithms and basic skills was definitely weakened because of the convenience, so I also used it for self-improvement and reflection. I started making simple things.

Subject

A simple program that notifies you when you can catch fish

・ Check the current time to determine if it is a fishing time zone

・ The status is as follows 6: 00-8: 00 → Morning mazume (because phytoplankton rises to the surface for photosynthesis) 8: 00-17: 00 → Daytime (basic activity is sparse, sometimes you can catch) 17: 00-19: 00 → Evening Mazume (Large fish activate in search of small fish) 18: 00-6: 00 → Night (fish start moving. You can also aim for large fish)

sample

mazumeAlert.java

import java.util.*;
import java.text.SimpleDateFormat;

class mazumeAlert {

	public static void main(String[] args){
		
		String display_result = "";		
		Calendar cTime = Calendar.getInstance();
		
		SimpleDateFormat sdf = new SimpleDateFormat("H");	
		int current_hour = Integer.parseInt(sdf.format(cTime.getTime()));
		
		if(current_hour >= 6 && current_hour < 8){
			display_result = OceanStatus.MORNING.getStatus();
		}
		
		if(current_hour >= 8 && current_hour < 17){
			display_result = OceanStatus.NOON.getStatus();
		}
		
		if(current_hour >= 17 && current_hour < 19){
			display_result = OceanStatus.SUNSET.getStatus();
		}
		
		if((current_hour >= 19 && current_hour <= 23) 
		|| (current_hour >= 0 && current_hour < 6)){
			display_result = OceanStatus.NIGHT.getStatus();
		}
		
		System.out.println(display_result);
	}

	enum OceanStatus {
		MORNING("Morning mazume:Time to catch"),
		NOON("Daytime: Reasonable time zone"),
		SUNSET("Evening Mazume: Fishing time"),
		NIGHT("You can catch all night");

		private final String status;

		private OceanStatus(String status) {
		this.status = status;
		}

		public String getStatus() {
			return this.status;
		}
	}
}

Afterword

It's not a big deal because it's a practice of looking back, but I would like to continue to accumulate logic that can be used steadily every day.
