How to assign values to an array by using an array passed in a constructor?

Question

I am trying to assign the values to the array products[] using the array arr[] which is passed in the constructor. When I compile the code I get the error

Shop.java:10: error: not a statement
products[]=arr.clone();
^ Shop.java:10: error: ';' expected
products[]=arr.clone();

How can I resolve the error and assign the arr[] values to the products[]

  import java.util.Scanner;
  public class Shop{
    private String shopName;
    private String shopAddress;
    private String products[];

    public Shop(String name,String add, String[] arr){
        shopName=name;
        shopAddress=add;
        products[]=arr.clone();
    }
}

I haven't given all the code, but assume

arr[]={"apple","orange","mango","banana"}

You should use products variable without [], because [] belongs to String to make it a String array, and your variable is products:

class Shop{
     private String shopName;
     private String shopAddress;
     private String products[]; // to avoid confusion I'd use String[] products;

 public Shop(String name,String add, String[] arr){
     shopName=name;
     shopAddress=add;
     products = arr.clone();
 }
}

In the code your variable's name is "products". No need for [] after products.

try

  products = arr.clone();
