Java – read multiple scanner inputs
•
Java
What I want to do is have multiple inputs with different variables Each variable is part of a different equation I'm looking for a way to do this, and I think I have an idea I just want to know if it's legal and if there's a better way to do it
import java.util.*; public class Example{ public static void main(String args[]){ Scanner dd = new Scanner(system.in); System.out.println("Enter number."); int a = dd.nextInt(); System.out.println("Enter number."); int b = dd.nextInt(); System.out.println("Enter number."); int c = dd.nextInt(); } }
Solution
If each input asks the same question, use the for loop and the input array:
Scanner dd = new Scanner(system.in); int[] vars = new int[3]; for(int i = 0; i < vars.length; i++) { System.out.println("Enter next var: "); vars[i] = dd.nextInt(); }
Or, as chip suggests, you can parse the input from one line:
Scanner in = new Scanner(system.in); int[] vars = new int[3]; System.out.println("Enter "+vars.length+" vars: "); for(int i = 0; i < vars.length; i++) vars[i] = in.nextInt();
You're on the right track. What work have you done It's just a better, more flexible way of doing things
