Thread: What is the issue with my code

Hello,

I am trying to learn Java and ran into a problem with my code that I can seem to figure out. On line 17 it says this method must return a result type int. any guides would be appreciated.

 import java.util.Scanner;
 
public class Sticker {
 
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		//Variables
		System.out.print("Enter a value for wc: ");
		int wc = scan.nextInt();
		System.out.print("Enter a value for hc: ");
		int hc = scan.nextInt();
		System.out.print("Enter a value for ws: ");
		int ws = scan.nextInt();
		System.out.print("Enter a value for hs: ");
		int hs = scan.nextInt();
	}
		public static int solve(int wc, int hc, int ws, int hs) {
			if (wc -ws < 2)
				return(1);
		else 
			if (hc - hs <=2)
				return(0);
 
 
 
		}
}

The compiler requires that the value method return an int value for ALL possible conditions. The current code only returns values inside of if statements.
What if those if statements are not true?
There needs to be a return statement for when the if statements are not true.

why i'm not outputting my results? Any Ideas?

Same problem as before. There is a way for none of the if statements to be true. If they are all false, nothing is printed.
Add a print statement at the end of the method that prints out the values being tested in the if statements so you can see why the if statements are not true,
