Question

I wrote a function in Java and I want this function to return multiple values. Except use of array and structure, is there a way to return multiple values?

My code:

String query40 = "SELECT Good_Name,Quantity,Price from Tbl1 where Good_ID="+x;
Cursor c = db.rawQuery(query, null);
if (c!= null && c.moveToFirst()) 
{
  GoodNameShow = c.getString(0);
  QuantityShow = c.getLong(1);
  GoodUnitPriceShow = c.getLong(2);
  return GoodNameShow,QuantityShow ,GoodUnitPriceShow ;
}

Answer 1

In Java, when you want a function to return multiple values, you must

• embed those values in an object you return
• or change an object that is passed to your function

In your case, you clearly need to define a class Show which could have fields name, quantity and price :

public class Show {
    private String name;
    private int price;
    // add other fields, constructor and accessors
}

then change your function to

 public  Show  test(){
      ...
      return new Show(GoodNameShow,QuantityShow ,GoodUnitPriceShow) ;
