BusData data=new BusData();

in Search.java is probably empty hence nullpointer with data.JourneyArray[position]

I think you need to add a method in Main.java to retrieve the field 'data' from other classes.

Main.java

...
public static BusData getData() {
    return data;
}

Search.java

//BusData data=new BusData();
BusData data = new Main().getData();

I didn't give you the full solution...

you need to create a constructor in Main.java and run your Main.main() method before you use getData() otherwise the field 'data' still won't have any values in it

[coopc]

So do I add this to the Main.java:

	BusData datas;
	public Main()
	{
		datas=null;
	}
	public void setData(BusData  datas)
	{
		this.datas=datas;
	}
	public BusData  getData() 
	{
		return datas;
	}

and then add this in Search.java:

BusData data = new Main().getData();

I tried that and i still have the same error

datas = null? no, you're supposed to run your whole method so that you fill up data with actual values.

public class MyClass {
  private BusData data;

  MyClass() {
      main();
  }

  public static void main() {
      data = new BusData();
      for(int i=0; i<someObject.length; i++) {
           data += someObject[i].value();
      }
  }

  public BusData getData() {
    return data;
  }
}
