Incompatible types : Int cannot be converted to “class” data type

I’m trying to insert value to a List using loop for, but this list data type is a class which have constructor in it. Here is my code :

List<Edge> edge= Arrays.asList();
    for(int i=0;i<M;i++){
        System.out.println("insert first vertex that connected to edge : ");
        x=key.nextInt();
        System.out.println("insert second vertex that connected to edge : ");
        y=key.nextInt();
        edge.add(x,y);
    }

And the error message on line edge.add(x,y) it says :

Incompatible data types : int cannot be converted to Edge

Here is the Edge Class :

public class Edge{
    int source, destination;
    public Edge(int source, int destination){
        this.source=source;
        this.destination=destination;
    }
}

What should i change? Thank you.

Answer

Changing edge.add(x,y) to edge.add(new Edge(x,y)) should help. The list edge expects an Object of class Edge, while two ints are being passed, causing the error.
