Answer 1

Use Arrays.toString(products) to convert the array contents to a String

https://docs.oracle.com/javase/7/docs/api/java/util/Arrays.html#toString(java.lang.Object[])

Answer 2

One way of solving this is to add a toString() method to you Product class. If your Product has two attributes, title and price the toString() could be something like

 public String toString(){ 
   return title=" + getTitle() + ", price=" + getPrice()
 }  

Many IDEs has support for generating toString() methods. See fx https://www.jetbrains.com/help/idea/generate-tostring-dialog.html
