The main method – queues

The main method creates two orders, and the priority of the orders is set to 2 and 1. In the following code, the queue will first process the order with the higher number on the priority value:

// main method
func main() {
 var queue Queue
 queue = make(Queue,0)
 var order1 *Order = &Order{}
 var priority1 int = 2
 var quantity1 int = 20
 var product1 string = "Computer"
 var customerName1 string = "Greg White"
 order1.New(priority1,quantity1,product1, customerName1)
 var order2 *Order = &Order{}
 var priority2 int = 1
 var quantity2 int = 10
 var product2 string = "Monitor"
 var customerName2 string = "John Smith"
 order2.New(priority2,quantity2,product2, customerName2)
 queue.Add(order1)

 queue.Add(order2)
var i int
for i=0; i< len(queue); i++ {
fmt.Println(queue[i])
}
}

Run the following commands to execute the queue.go file:

go run queue.go

After executing the preceding command, we get the following output:
