    Default REQUEST : Making a Basic program which creates two method and calls them in main method

    Write a program which adds or subtract two number
    here are condition:-
    1. make a method which will add two no.
    2. make a method which subtract the two no.
    3. ask user if they wanna add or subtract and then call the method needed as per need
    i am deeply confused and will really appreciate anyone who will make this basic script from which i can observe my mistake
    here is my code for reference if you need but it is not working
    import java.util.Scanner;
    public class sum {
    	static Scanner input = new Scanner(System.in);
    	public static double addition(double s1 ,double s2 ) {
    		double sum1 = s1 + s2;
    		return sum1;
    	}
        public static double subtraction(double s1, double s2) {
    double sum1 = s1-s2;
    return sum1;
    }
        public static void main(String args[])
    {
    	double n1, n2, sum;
    	System.out.println("welcome do you want to add or divide");
    	String s = input.next();
    	if (s.equalsIgnoreCase("add") || (s.equalsIgnoreCase("addition")))
    			{
    		System.out.println("enter the two numbers");
    		n1 = input.nextDouble();
    		n2 = input.nextDouble();
    		 sum = addition(n1, n2);
    		System.out.println(sum);
    	}
    	else if (s.equalsIgnoreCase("minus") || (s.equalsIgnoreCase("subtraction")))
    	{
    		System.out.println("enter the two numbers");
    		n1 = input.nextDouble();
    		n2 = input.nextDouble();
    		 sum = subtraction(n1, n2);
    		System.out.println(sum);
    	}
     
    }
    }

    Please explain.
    If there are error messages, copy the full text and paste it here.
    If the output is not what you want, copy and paste the output here and show what the desired output is.
    If you don't understand my answer, don't ignore it, ask a question.

    Except for the problem that you prompt to add or divide and not add or subtract, the program works fine for me. What problem are you supposedly having?
