Parameter/Argument Method Passing Question

[nvibest]

Hello,
I have a method:

  	public Cube(String id, String faceValues){
		this.id = id;
		id.toUpperCase();
		for (int i =0; i <6; i++){
			faces[i]=faceValues.charAt(i);
		}
		faceIndex = 0;
		rnd = new Random(0);

	}

What I'm trying to do is obtain input from the user and set their input as the 'String id' parameter in the above Cube(String id, String faceValues) method:

 import java.util.Scanner;
public class CubeTester {
	//Instance variables
	private Cube c1;
	private Cube c2;
	private Cube c3;
	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		//Constructor 
		Cube c1 = new Cube();
		Cube c2 = new Cube();
		Cube c3 = new Cube();
		//Ask for String id
		System.out.println("Enter cube id: ");
		scan.next(); // I want to set this as String id in the Cube method
		//Then ask for the String faceValue 
		System.out.println("Enter 6 letters for faces of the cube: ");
		scan.next(); //I want to set this a the String faceValue in the Cube method
	}
}

Any help would be greatly appreciated.

Thanks,

n

First, you have a constructor, not a method.

Second, every time you call scan.next() it reads from system.in. so if you do something like

int i = 0;
String[] values = new String[6];
while(i < 6) {
values[i] = scan.next();
i++;
}

You'll get a string[] with the 6 entries from System.in Then you can initialize the cubes likes this:

Cube c1 = new Cube(values[0],values[1]);
Cube c2 = new Cube(values[2],values[3]);
Cube c3 = new Cube(values[4],values[5]);

Ah, thank you. I've modified my code to understand a little better:

import java.util.Scanner;
public class CubeTester {
	//Instance variables
	private Cube c1;
	private Cube c2;
	private Cube c3;
	public static void main(String[] args) {
		//Constructor 
		Cube c1 = new Cube();
		Cube c2 = new Cube();
		Cube c3 = new Cube();
		
		
	}
	
		private Cube createCube (Scanner keyboard){
			System.out.println();

			System.out.println("Enter cube id: "); //Ask for String id
			String id = keyboard.next(); // I want to set this as String id in the Cube method
			System.out.println("Enter 6 letters for faces of the cube: "); //Then ask for the String faceValue 
			String faceVal = keyboard.next(); //I want to set this a the String faceValue in the Cube method
			return c1;
		}
