Question

In Java, how do I include a scanner when using methods? Example, method for the perimeter of x and y values.
This is my code:

import java.util.Scanner;

class test {

public static void main(String[] args) {
Scanner type = new Scanner(System.in); // scanner
double x, y, answer;
System.out.println("Enter value for x; ");
x = type.nextDouble();
System.out.println("Enter value for y; ");
y = type.nextDouble();

}

public void perimeter(double x, double y){ //perimeter method
double ans = x + y;
System.out.println("The perimeter is "+ans);
}

}

Answer 1

What do you mean? Once you have read the values in you can simply pass the values to your methods and do what you need.

Answer 2

looks like it should work:
String str = "9.72 8.75"; // the input string
Scanner type = new Scanner(str);
double x = type.nextDouble();
double y = type.nextDouble();
< do something with x and y....>

Answer 3

you want to enter both x and y on one line...enter x and y: 9.85 10.74

Answer 4

ah.... if perimeter is being called from main, it must be declared static -
public static void perimeter(double x, double y){
<stuff>
}
now call perimeter from main:
< get x and y >
perimeter(x,y); // last statement in main
}

(I hope i've run out of things to say now....) (and that it works....) (and i have understood...)
