    Default Need some advice URGENT! thanks!!

    hey everyone,
    i need to know whats missing to do to be able to
    initialise my program such that i can have this possible run

    heres the code:
    import java.util.*;
     
    public class Resistance {
     
    	static Scanner input = new Scanner(System.in).useDelimiter("\r\n");
     
        public static void main(String[] args) {
        	double r1 = 0, r2 = 0, r3 = 0, rTotal = 0, rTotalpara = 0;
            int choice;
            int choice2;
            int loop = 0;
            while(loop < 10)
            {
            System.out.println("          Resistance Calculation            ");
        	System.out.println("          ======================            ");
            System.out.println("1> Resistance in Series  ");
            System.out.println("2> Resistance in Parallel");
            System.out.println("3> Exit                  ");
            System.out.println("=========================");

    That's not really how this works. People hesitate to click external links. And did you seriously just take a picture of your homework assignment?

    If you want help, ask a specific question. What is your program doing? What do you expect it to do? What happens when you step through it with a debugger?
