Apps How do you pass variables between classes?

[deenybird]

What intents do I use to pass a variable to another class? And also which intent do I use to receive it?
thanks

Why per Intents?
You can pass variables by creating an objekt of another class...
Like here:

public class Main {

static Test t = new Test();
public static void main(String[] args){
t.Set(3);
System.out.println(t.Get());
}

}

extra file:

class Test{
private int i;
public int Get(){
return i;
}
public void Set( int a ){
this.i = a;
}
}

I hope that helps

BTW: There is no main in android, so just do this without an main...
in any class you wish...

check out this I had a question on this, and posted the Idea I had, so if it comes to be its a good idea, or you try it out, let me know what you think, hopefully by tomorrow someone'll tell me if i have an obvious flaw in this idea

To pass variables between classes you use getters and setters.

Examples

class Rectangle {
  int x;
  int y;
  int width;
  int height;

  public int getX() {
    return this.x;
  }

  public int getY() {
    return this.y;
  }

  public int setX(int x) {
    this.x = x;
  }

  public int setY(int y) {
    this.y = y;
  }

  // etc etc
}

// In another class you'd have:

Rectangle r1;

r1.setX(50);

int example = r1.getX();
