Passing values from main class to other classes in Java

Passing values from main class to other classes in Java

I'm on a project that requires passing values from main class to other
classes. All of the classes are correctly working when they have their
main functions. However, my project should have only one main class that
calls other functions in other classes.
An example for main and another class is below. I want to scan the input
through main class and pass it to parse class. Current implementation
gives two error which are:
Exception in thread "main" java.lang.NullPointerException
at url.checker.Parse.GetInput(Parse.java:16)
at url.checker.Main.main(Main.java:14)
Java Result: 1
**Given input: -url=google.com,-time=5,-email=asdfg@hotmail.com**
Main.java:
package url.checker;
import java.util.Scanner;
public class Main {
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.println("Enter the parameters as '-url=' , '-time=' ,
'-email='.");
Parse.s = in.nextLine();
Parse.GetInput(Parse.s);
}
}
Parse.java:
package url.checker;
import java.util.Scanner;
public class Parse
{
static String s;
static String result[];
public static void GetInput(String s)
{
int i;
for(i=0;i<3;i++)
{
if (s.startsWith("-url="))
result[0] = s.substring(5, s.length());
else if (s.startsWith("-time="))
result[1] = s.substring(6, s.length());
else if (s.startsWith("-email="))
result[2] = s.substring(7, s.length());
else
System.out.println("You didn't give any input.");
}
}
}
Thank you very much for your help.
