Java在多个类之间传递数据

Question

可以在多个类之间传递数据吗

class Original{
   private int x;

   public void setX(int x){
      this.x = x;
   }
}
//
class Setter{
   Original original = new Original();

   original.setX(5);
}
//
class Consumer{
   //use the value "5" here which came from Original->Setter
}

我试图实现的是“一个类设置某个类的值，另一个类访问它”

Answer 1

class Original{
    private int x;
    public void setX(int x){
        this.x = x;
    }
    public int getX(){
        return x;
   }
}
class Setter {
    private Original original;
    Setter (Original o) {
        original = o;
    }
    public void set(int x){
        original.setX(x);
    }
}
class Getter {
    private Original original;
    Getter (Original o) {
        original = o;
    }
    public int get(){
        return original.getX();
    }
}
public class MyProgram {
    public static void main (String args[]) {
        Original original = new Original();
        Setter setter = new Setter (original);
        Getter getter = new Getter (original);
        setter.set(5);
        getter.get();
    }
}
