Question

Right now I have two .java files.
The Main.java:

public class Main {
    static int integer = 15;
    NeedInteger need = new NeedInteger();
}

and the NeedInteger.java

public class NeedInteger {
    System.out.println(integer);
}

This is of course very simplified, but is there any way I can accomplish this?

Answer 1

As many have answered, the correct method is to pass the value in to the constructor of the new class.

If for some reason you cannot do that, then you can use a public static accessor method in Main to access the value (this would be slightly better than just making the field public).

E.g.

public class Main
{
  private static int integer = 15;

  public static int getInteger()
  {
    return integer;
  }
}

public class NeedInteger
{
  public NeedInteger()
  {
    int integer = Main.getInteger();
  }
}
