Thread: Help with logic to find the day number of the year

Hello, I need help with figuring out the logic to print the day number of the year. The directions for my homework are: Write a program that prints the day number of the year, given the date is in the form: month day year. For example, if the input is 1 1 05, the day number is 1; if the input is 12 25 05, the day number is 359. The program should check for a leap year . I have a basic outline of the program but i am having trouble with figuring out the logic to display the day number of the year given the date. This is what i have so far

import javax.swing.JOptionPane;
 
public class Practice4
{
	public static void main(String[] args)
	{
	    String monthStr;
	    String dayStr;
	    int inputMonth;
	    int inputDay;
	    String yearStr2;
	    String dayStr2;
    	int inputyear2;
        int inputDay2;
 
    	String[] Months = {"January", "February", "March", "April", "May",
            			   "June", "July", "August", "September", "October", "November",
            			   "December"};
 
    	int[] Days = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
 
    	monthStr = JOptionPane.showInputDialog(null, "Enter the Month: ");
    	inputMonth = Integer.parseInt(monthStr);
 
    	dayStr = JOptionPane.showInputDialog(null, "Enter the Day: ");
    	inputDay = Integer.parseInt(dayStr);
 
    	yearStr2 = JOptionPane.showInputDialog(null, "Enter the year: ");
    	inputyear2 = Integer.parseInt(yearStr2);
 
    	JOptionPane.showMessageDialog(null, );//To display the day number of the year
 
    	public static int dayNumber(int dayCount)//Method for logic to find day number
    	{
			for( )//Need help figuring out logic to print day number of the year
        	{
          	boolean isLeapYear = (year % 4 == 0 && year % 100 != 0)||(year % 400 == 0); //accounting for leap year(probably doesnt go here)
        	}
 
    	}
	}
}

Norm, I dont have anything as of yet... I think I need to assign the date to a number then keep a running count until December 31st. I am unsure of how to just single out the month and day from the year though.

Right I could use the Scanner class and use nextInt method 3 times and assign them to a variable. I will definitely do that. The program needs to read those numbers and keep a running total of the day of the year it is and account for a leap year if it is inputted by the user.

What do you mean by high level?... I have not worked out the "details" do I make some sort of loop? maybe a for loop or should i use the switch method? and if i use a for loop how would I get a counter to count the days from what the user inputs?
