ArrayList contains and equals

This is my Hole Class

class Hole { public int a; public int b; Hole(int a, int b) { this.a = a; this.b = b; }

So i adding an ArrayList that contain several several hole

public void checkPathLoop(int x, int y) { //rough code ArrayList leftFlowInnerHole = new ArrayList<>(); //left holes rules leftFlowInnerHole.add(new Hole(0, 1)); leftFlowInnerHole.add(new Hole(1, 5)); leftFlowInnerHole.add(new Hole(5, 4)); leftFlowInnerHole.add(new Hole(0, 4));

when i add

Hole userInputHole = new Hole(0,1); System.out.print(leftFlowInnerHole.contain(userInputHole));

it always return false !! it suppose to return true.

Is there anything i miss ??

Thank you in advance
